The Entire World

It is surprising how in a crowded, noisy environment you can still create your small world. This is one of the most amazing changes that have been made by headphones. Small devices with a big impact on the world are the only way to describe headphones. In the past, the only way to listen to music was through devices that allowed everyone to listen to music at the same time. With the introduction of headphones, you don’t have to bother everyone with your music; you can create your space and enjoy listening to what you like directly to your ears.

How headphones have changed over time

Early headphones were mainly used for communication purposes. The birth of headphones in early 19th century was purely for communication and professional uses. It is strange how the creator of headphones Nathaniel Baldwin didn’t have the musical concept in mind. The uses of headphones at this time were purely for professional uses by people in the army and also church coordination.

Discovery of stereo phones for music was a big break in the mid-19th century, the whole perspective of headphones changed from professional use and they were given a musical touch. The musical evolution changed the concept of headphones, and this gave birth to the stereo phone technology to cater for musical fanatics. This was when headphones specifically for music were created, but they were expensive.

Light weight portable headphones were discovered in the 1980s there was a big break after everything went mobile. The headphones now become lighter, and you could see youngsters carrying them around. The growth of the pop culture at this time might have had a huge impact on how people wanted to listen to their music and this made headphones grow more. The sound quality becomes better at this time.

Modern fashion statement headphones are now common to bring out personality and social standards. The headphones that we have now are bringing the fashion statement in mind. The unique design and the big brand names like Beat by Dre are bringing a new perspective on the way we view headphones. The technological advancement is sound quality is now improving due to latest technological innovations.

Benefits of headphones in the modern world

Good sound quality and faithfulness is one of the main benefits of headphones. We all agree listening to music through headphones feels good compared to listening through loudspeakers. The reason for this is quite listening simply. Music from headphones has no interference from external forces and especially if you are listening to music through quality headphones.

The concentration at work is now better with headphones. With the use of headphones, it is now possible to get peace of mind and keep up concentration whilst working. It is surprising how music takes us to a new world where we can be able to reflect and focus on the work we are doing. This is the reason why you will find people working in jobs that need a high level of concentration using headphones all the time.

Peace of mind and calming stress is a major reason why many people use headphones. Music is therapeutic, and it works wonders in relieving stress and restoring peace of mind. Listening to music through external speakers is good for entertainment but not necessarily for healing. There is something special about listening to music through headphones because it brings calmness and brings back peace of mind.

Privacy is one thing that many people seek in the crowded and noisy world. If you want to maintain privacy, then you can easily escape in your headphones and get the privacy that you need. People around you will understand that you need privacy and allow you to have your solitude.

Who uses headphones?

The uses of headphones are now limitless, and they go beyond just for the sake of entertainment and communication purposes.

Music lovers get lost in their headphones for hours listening to music without interrupting the rest of the world with the type of music that they love. Using headphones, music lovers can get the sound effect that they want from the headphones through sound effect settings.

Transcribers who translate audio content into text need headphones to be able to listen to what they are typing. This is one of the most common professional use of headphones. Other people like pilots, recording artists and also the military use headphones in their job.

A giant solar storm nearly triggered a nuclear war in 1967

We all know how important radio communications are and at a time before the internet and even digital communications, governments relied on RF communications that were susceptible to the suns solar storms, if you add that to the cold war nuclear tensions then we could all be living in holes now.

Cold War history is rife with close calls that nearly led to nuclear holocaust.

In September 1983, for example, sunlight reflecting off a patch of clouds fooled a Soviet missile-warning system into detecting the launch of five US intercontinental ballistic missiles that never were. A wary colonel in a bunker ignored the alarm on a 50/50 hunch.

Two months later, US forces staged “Able Archer 83” — a massive nuclear-strike drill on the doorstep of the USSR. Soviet commanders panicked at the show of force and nearly bathed America in thermonuclear energy. Once again, an act of human doubt saved the planet.

Now scientists have one more hair-raising event to add to the books: The “Great Storm” of May 1967.

“The storm made its initial mark with a colossal solar radio burst causing radio interference … and near-simultaneous disruptions of dayside radio communication,” a group of atmospheric scientists and military weather service personnel wrote in a new study, published August 9 in the journalSpace Weather.

Hours later, high frequency communications dropped out near US military installations in and near the Arctic — one of the closest places to station nuclear weapons and launch them at a Cold War-era Soviet Union.

“Such an intense, never-before-observed solar radio burst was interpreted as jamming,” the study authors wrote. “Cold War military commanders viewed full scale jamming of surveillance sensors as a potential act of war.”

A ‘Great Storm’

Earth’s magnetic field protects life on the planet by corralling the sun’s high-energy particles toward the planet’s polar regions.

If the sun happens to launch a cloud of solar particles directly toward Earth during a violent outburst, called a coronal mass ejection, it can trigger powerful geomagnetic storms.

This not only leads to beautiful auroras, but can also scramble wireless communications and disrupt radar systems.

While The Washington Post wrote up a story about the storm as “City Gets Rare Look at Northern Lights,” top US military commanders sounded the alarms in secret.

The Air Weather Service (AWS) — a relatively new branch of the Air Force — had warned military leadership about the possibility of a solar storm, but US commanders believed the Soviet forces were jamming NORAD systems designed to detect threatening planes and missiles.

As the Strategic Air Command warmed up the engines of bombers and taxied toward the runway, the decision to go airborne may have been kicked all the way up to the “highest levels of government,” possibly involving President Lyndon B. Johnson.

“Just in time, military space weather forecasters conveyed information about the solar storm’s potential to disrupt radar and radio communications,” according to a press release from the American Geophysical Union. “The planes remained on the ground and the U.S. avoided a potential nuclear weapon exchange with the Soviet Union.”

And this all happened at the peak of nuclear armament — when a record 31,255 nuclear weapons were deployed around the world. (Today there are roughly 7,200 nuclear armaments at hand.)

“Had it not been for the fact that we had invested very early on in solar and geomagnetic storm observations and forecasting, the impact [of the storm] likely would have been much greater,” study leader and UCAR atmospheric scientist Delores Knipp said in the release.

After the near miss, the researchers say the military learned to listen to its space weather forecasters, improve its abilities to see another looming “Great Storm,” and avert the first and perhaps final global nuclear exchange.

What is the Best two way Radio For Very Long Range

When choosing the best two way radio, it is important to note that doesn’t matter which brand you pick. Whether you pick kenwood, Motorola, Icom, Hytera or any other brand, you should know that they all feature the same technology. Well, you might have noticed that most consumer radios tend to advertise a range that’s up to 30 miles. Truth is, the consumer FRS/GMRS radios don’t even provide anything close to the advertised maximum range; the range that a two way radio advertises is normally the range that a radio can get in the ideal condition. The ideal condition is clear line of sight like from the mountain top to the valley below; without any interference or obstructions.

Two way radios generally operate within VHF (that is Very High Frequency; 130 to 174MHzz) and UHF (that is, Ultra High Frequency; 420 – 470 MHz)) wave bands. Unlike the frequencies that are below 2MHz, the waves in these particularly higher frequencies travel in a straight line (also known as line of sight signal), and generally can’t travel beyond your horizon. This basically means that distance to your horizon, is the actual maximum range for your two way radio; that is without the use of any additional equipment to boost the signals.

VHF waves (about 5 feet wide), are generally longer than the UHF waves, and they’re most commonly used for long range/distance communication. If VHF waves and UHF waves were both transmitted in ideal conditions without any barriers, the VHF waves would travel nearly twice as far; as a general rule, the lower the wave frequency, the greater the distances it can travel.

Key to transmitting the radio waves for a long distance along the VHF waves is keeping the receiver and the transmitting radio above all possible obstructions or interfering objects. The VHF frequencies (because of the length of their waves), cannot transmit through some objects like walls, dense forests and hills. Typically, the transmissions which are sent along VHF waves are received and also sent high above earth’s surface. VHF 2 way radios normally work better when there is a clear line of sight between the receiver and the sender. VHF 2 way radios are commonly used in marine and aviation communications where signals get sent across the open water bodies or between the ground and the sky. Television and FM radios also use the VHF frequencies where the signals are sent and also received high at the top of towers which are spaced all over the towns, cities and counties. VHF band walkie talkies are also perfect for landscaping, open fields, golf courses and also for outdoors security situations where there is less obstruction.

Though VHF can travel much farther, it doesn’t mean it is the better option. Reason is because of the differences between how the VHF and the UHF signals tend to react around buildings or structures. As you will find out below, UHF signals are shorter than VHF, and this is very important when you’re in or around buildings.

UHF doesn’t travel as far as the VHF, but has higher bandwidth occupation. One major advantage of UHF over the VHF, is that the antenna can actually be much smaller when its’ used on the higher frequencies. Sometimes, a base antenna might be needed for radios using VHF frequency, but a small antenna on a radio can be comfortably used for the UHF frequency. Moreover, there are a lot more frequencies which are available when using UHF; this can be very useful in the areas which have a high population density.

The UHF radio waves are much shorter than the VHF radio waves (measuring at about one and half feet); the short length of UHF radio waves typically decreases distances at which the signals can get transmitted. This means that the line of sight between the receiver and the sender is much shorter in length with UHF waves. That being so, you should know that transmission of the UHF waves is usually high enough such that it can penetrate through the building walls and the urban outdoor settings. This is the reason why UHF 2 way radios usually work best for those who intend to use them in and around buildings and urban areas. A UHF walkie talkie with adequate power and a good sized antenna can reach further into the building, and push through steel, wood, concrete and earth. If you intend to use your two way radios exclusively indoors, or maybe indoors and at times outdoors, the the UHF is definitely the best choice. To explain this, let us use an example; assume you’re trying to communicate with someone on the other side of the building and in between there’s a metal wall which has a 3 foot opening. Basically, radio waves can’t pass through metal. However, the UHF wavelength which is about 1 1/2 ft wide, will easily pass through the opening. In contrast, the VHF signal will bounce back since it’s wider than the opening. This shows you that UHF is much better when it comes to navigating through smaller spaces within buildings to reach its’ destination.

When it comes to power, many people tend to think that the power output increases the range, but actually the difference in the range between, say a 25W fixed VHF, and a 5W handheld, is because the fixed mounts the antenna being taller, thus can see farther. When you are trying to increase the range, increasing the height of your antenna is far more effective than increasing the power. Increased power will generally let you push through the static and such other radio traffic much better, but only within a range that’s dictated by the height of the antenna.

In regards to obstacles, there are a lot of things which affect the signal strength of the radio waves. Therefore, it’s important to consider the environment you intend to use your 2 way radios, and the actual range you need. Naturally, a football stadium will have much less obstructions as compared to a dense forest.

In conclusion, I would like to say that it is never about the radio you purchase, but the frequency, antenna and environment it will be used in. If your 2 way radio is going to be used mainly outdoors, where you will have a clear line of sight, then the VHF is the ideal choice, however, if the 2 way radio is going to be used in and around buildings, in urban areas, or in heavily wooded places, then the UHF is the best option.

GPS Tracking: The Way It Works

GPS (Global Positioning System) is a network of 24 satellites placed in orbit for navigation purposes. It was invented in 1960 and positioned by the US Department of Defense for military work but later released to the public as well. GPS navigation system works 24 hours a day anywhere in the world, and is free to use. The system sends signals to navigation devices to calculate the exact location, time and speed of a vehicle, person, aircraft or water equipment. Today it’s used widely by drivers, trucking companies, and shipping firms to track their cargo and know the best route to use.

How GPS Tracking Works

There are at least four satellites available anywhere one stands on earth. All the satellites circle the earth two times a day and send signals to various areas. Any GPS receiver including mobile phones takes this signal information and calculates the user’s location.

How this method works involves calculating the difference between when the signal was sent and when it was received. This difference tells the receiver how far the satellite is, and the distance comparison of several satellites within the same area confirms the location on the electronic map.

The more satellites found within a receiver’s location, the easier it is to calculate speed, distance, and destination. At least three satellites are needed to calculate position, but a fourth satellite makes it possible to tell the speed, direction and estimated time when you are on the move.

Personal Tracking

Mobile GPS technology has made it possible to track people wherever they are. Today any phone can be tracked by the police or mobile service providers. Other mobile devices that help with tracking include jewellery such as watches, bracelets and even chips embedded in the skin.

Smartphones are also equipped with built-in GPS system that can provide the user with direction and navigation instructions. Most of these phones can tell you exactly where you are, including streets and attraction figures. They can alert you if you are going the wrong direction and give you the correct navigation.

Asset Tracking

It is so easy to track your cargo when it’s on the go. A tracking device or chip can be placed on the assets to know exactly where they are, the direction they are heading and when movement stops. Animal tracking devices are also commonly used to locate where cattle and wildlife are all the time.

Aircraft Trackers

GPS aircraft tracking is essential for both private and commercial planes. Though the primary agenda is safety and convenience, GPS works differently on the aircraft as compared to how it’s used in cars. Aircraft tracking enables traffic controllers to know the position of the plane and keep it safe when flying.

GPS also help the supervisors know when the plane will arrive and find it in the case of an accident. However, the greatest use of GPS tracker in aircraft is to ensure the pilot follows a particular path predetermined by the aircraft controller.

Vehicle Tracking

A GPS-enabled tracking device is placed on a vehicle to transmit data through cellular or satellite networks. This device will send the data to a chosen application such as NetTrack for the user to read. The tracking updates and information such as location, speed, direction and stop come in real-time.

GPS tracking system for vehicles enables people to track their cars when they are stolen, keep a tab on your business tracks and know where your child is with the car. It’s an easy and convenient way to keep track of vehicles, be it trucks, small vehicles or fleet of buses.

GPS and Two-Way Radio Integration

Two way radios are great devices used by campers, police force, and emergency dispatch for safety, tracking, and communication. However, they have shortcomings such as lack of real-time transmission, slow updates and being unreliable. Two way radio with GPS makers such as Garmin has integrated their systems with GPS capabilities. The GPS will help to know where someone is at all times even when the device is off, update locations in real time and store data for future use. It’s also handy in case of emergencies to get help and aid search activities.

UK Law

In the United States and most of the other developed countries, the use of GPS tracker by government authorities is limited. They must have a search warrant. Otherwise, any data found will not be admissible in court.

However, UK Law has no specific legislation on GPS trackers. The United Kingdom does recognize that some information is personal data, but it allows government surveillance without permission.

What 2 way Radio Channel Do I Need To Use

You may get confused about various types of walkie talkies on sale in the UK, or not be certain what type of walkie talkies you require , and what you’re legally allowed to use in some other countries that you plan to visit, or in your part of the world. Firstly, it is important to have in mind that any type of walkie talkie will function in any part of the world.

A walkie talkie is used on a channel that has a frequency associated with the walkie talkie. In other words, if a channel has a frequency different from that of a walkie talkie, then the two will not work together.

License Free Walkie Talkies

There are 446 license-free frequencies that can be used for leisure radios such as, Motorola talkabout, Binatone and Cobra radios. However, there are eight PMR466 frequencies or PMR466 channels that can be used.

The spacing between each of these frequencies is 12.5 kHz. As the system name suggests, PMR446 frequencies are located around 446MHz and are in the UHF segment of the radio range.

Even though they are not necessarily authorized, PMR446 frequencies are harmonized for use across European countries.

High level use of PMR446 frequencies may result in some annoying problems. However, these can be reduced or rectified by changing the frequency of the PMR446. Other systems such as DCS codes and CTCSS tone can as well help in alleviating the problems.

In view of the possible high use of the frequencies and the PMR446’s unlicensed nature, the scheme is not appropriate for individuals who need to gain access to frequencies at specific times and locations or for life use.

These are simple, short-range walkie talkies that conform to the European Union-wide PMR446 standard and can be used by any person in the United Kingdom or European Union without a license. These types of radios are commonly sold in High-Street shops as well as in most radio outlets.

Commonly known as “PMR446s” radios that meet these standards usually have a power output of 0.5watts, meaning that their range is lower compared to the powerful business walkie talkies that are a licensed and which feature power outputs of 4-5 watts. All of them make use of the same eight channels and this causes problems sometimes if a given area has a lot of radio users using these channels.

Licensed Walkie Talkies

Two Way Radio for Business

Licensed handheld walkie talkies can have a power output of 5 watts, but “license free” PMR446 walkie talkies can only have 0.5watt power output. Therefore, the licensed walkie talkies usually have a better signal penetration and better range in buildings.

A majority of businesses prefer using a licensed 2-way walkie talkie system because, in spite of the benefits of license free walkie talkies (PMR 446), they have some downsides (like lower power, a short range and interference) which make them less effective than licensed business radio systems.

Taxi as well as other transport companies, and large sites like factories or hospitals, and businesses situated in a number of different locations are excellent examples of circumstances where a licensed radio system may be a favored option.

These situations require more powerful radios as opposed to hand-held portable walkie talkies with low frequencies. If the system of your radio relies on vehicle-mounted radios or a base station, a licensed radio system is necessary.

Ofcom

If you want start using a radio system in your business, then you will have to get a license from Ofcom. In other words, Ofcom is a company that controls who can transmit on what frequency and where, to ensure that different users don’t interfere with each other.

Business radio system users range from factories and taxi companies, to industrial sites, hospitals, transport operators and care homes. To begin Ofcom’s licensing process there are a number of requirements that a business must first of all fulfil.

Ofcom license is especially important regarding official radio users like police, military, railways, air traffic control and emergency services, railways, etc. Radio systems that meet specific standards can be used without any license from Ofcom. For many walkie talkie users, license free radios will be okay. And if you are in need of a license, it isn’t that expensive or complicated to get one.

The UK simple license is a license issued by Ofcom and gives holders the right to use more powerful radios. It is effectively a license to use powerful radios any place in the UK, using give frequencies which are shared by anyone using this license. This license is easy and quick to apply for, costs about £75 per organization, and is valid for 5 years.

It is the only option for people who need to use their radio systems anywhere in the United Kingdom, and is ideal for most business radios users.

Geographic License

This license provides you with specific frequencies or frequency allocated just for your organization’s use within a given geographical area. The cost of the license varies from moderately cheap in most locations in the UK (about £100 annually), with the cost heightening in key cities, more so London, where the demand for radio frequencies is very high, going for up to more than £500 per year.

Radios that are designed to use dedicated frequencies such as this, should not be used outside of the licensed area, since the same frequency will possibly have been assigned to somebody else and you will therefore be causing interference to them.

UK Business Radio Suppliers License

This is a license for hire companies and radio equipment suppliers. It allows these companies to do short term radio hire via a set of frequencies allotted to radio hire companies. It also allows these companies to provide ‘demo’ radio systems to potential customers and to undertake repairs to radio systems.

When these companies hire out their radio equipment, it’s hired using this license, so that the person hiring it does need to worry about licensing issues.

Summary

The importance of walkie talkies and radios in the UK and other parts of the world cannot be overlooked. Not only are these gadgets important in everyday communication, but they continue to play a very crucial role in the development of other communication tools. A lot of useful information about radios and walkie talkies has been highlighted in this article for the benefit of radio users and the public in general.

Motorola Solutions Transforms Body-Worn Cameras for TETRA Users

Back in December the UK government decided on who and what will drive the new generation of emergency service communications. The ESN (Emergency Services Network) was the result of months of tendering and negotiations. So they decided that EE would manage the network and Motorola would provide the hardware. This article is about the first wave of communication devices that Motorola are planning to use with the ESN.

New innovative solution combines body-worn video camera, radio speaker and microphone with cloud-based data storage and management to create a complete digital evidence management system

At Critical Communications World 2016 (May 31 to June 2 in Amsterdam), Motorola Solutions announces a new combination of body-worn video camera, radio speaker and microphone, along with new, cloud-based, digital evidence management software, which is able to collaborate with TETRA digital two-way radios. The new “Smart Interface” (Si) Si500 Video Speaker Microphone (VSM) is reducing the number of devices that weigh down public safety officers in the field today, while CommandCentral Vault digital evidence management software is providing unparalleled efficiency that saves time and resources.

Public safety agencies today face an increasing demand to capture, store, properly manage and share video evidence. While use of body-worn cameras has widespread and growing acceptance with public safety agencies and the citizens they protect, the massive amounts of data cameras create needs to be managed and stored, oftentimes incurring significant costs. With its new solution, Motorola Solutions tackles all of these challenges and offers an end-to-end solution that can be used with existing TETRA radio equipment. Public safety agencies are provided with a seamless experience from video capture in the field to back office storage and content management that helps them simplify workflows and reduce administrative overheads.

  • Creates greater engagement and transparency with communities. The system enables agencies to improve evidence sharing and more easily respond to content requests.

The way to communicate with a 2-Way Radio

It is a wise idea to consider learning how to use a two-way radio in communications. By so doing, one is able to improve their experience in using a radio in communication. Over the years, a number of rules have been put in place to ensure that radio communications proceed more efficiently. These rules can be generalized as the etiquette for using two-way radios. Here are a few radio etiquette that should be considered when using a two-way radio:

Radio Etiquette Rules

It is important to bear in mind that English is the internationally recognized radio language. Users should ensure that they speak English when communicating with a two-way radio. However, there are exceptional cases where a user might be licensed to use other languages in radio communications.

It is not good etiquette to speak and listen to the person on the receiving end without allowing them time to finish what they are saying. This means that it is important to take turns when communicating with a radio. This is unlike the normal phone communication.

It is not good to interrupt someone. Rather, it is important to listen without interrupting other people. However, the only exception where one is allowed to interrupt is when they have some emergency information they would like to convey.

It is advisable not to respond to calls that one is not sure about. In such situations, it is wise to wait for call signs that confirm whose call it is before making any response.

It is wise not to ever transmit military, confidential, sensitive or financial information via a radio call. This is because radio communications can be tapped and be heard by the wrong recipients. Unless one is sure that their conversation is properly secured with high level encryption software, sensitive information should never be 2wayradionline.co.uk .

One should always perform checks on their radio to confirm that they are working properly. One should ensure that their radio battery is fully charged and its power is on. The volumes should at all time high. This will allow one to follow the conversation without strain. Additionally, one should ensure that they are within a range that can receive radio signals.

It is prudent to remember and memorize call locations and signs of radio stations and persons that one regularly communicates with. This is because name calling is discouraged in radio communications. People use call signs that are unique to everybody.

One should at all time think before speaking. This implies that one should not just say anything that comes in their mind but should carefully decide what to say. Communications should always be kept clear and precise. Additionally, one should not use complex sentences. Similarly, one should consider dividing long messages into shorter, separate messages for easy understanding. Abbreviations should at all times be avoided unless the receiving end understands the message.

Conclusion

When using a radio in communication, one should ensure that the voice is clear. It is wise to speak slowly and avoid shouting for clarity purposes. Radio messages should be kept simple, precise, and to the point. This allows brevity and simplicity in the entire conversation. As stated earlier, it is advisable to avoid radio transmission of confidential information for security purposes.

Can Listening To Headphones Cause Ear Infections

Technology is improving each and every day, but these advancements have left many of us tightly trapped in the luxuries and comforts, imposing many side effects on our overall health. One such modern advancement in technology that’s affecting our health is the use of headphones. Today, many people use headphones without knowing the kind of negative health issues the devices can cause.

Well, although headphones are an ergonomic, convenient and quite useful hands free accessories, there are various health risks that are associated with their use. Experts believe that prolonged use of headphones can cause great damage to the ears. In addition, headphones cause ear infections, which contributes to hearing loss. Well, some of the risks that are associated with headphones have more to do with their use and maintenance, than with the headphones mechanics.

Ear infections are much more likely to occur amongst the headphone users who wear the devices for extended periods of time, and also amongst those who don’t take good care of their headphones. For example, headphone ear cushions need to be replaced every 2-3 months, and should be treated regularly with the right cleaning agent so as to avoid accumulation of germs and bacteria. Prolonged headphone use also causes aural hygiene issues, hearing loss along with ear canal infections. Recent scientific studies have revealed that wearing headphones for extended periods of time usually increase the humidity and the temperatures inside the ear canals, thereby increasing one’s susceptibility to ear infections. This shows that headphones cause ear infections.

Sharing of headphones is another way headphones cause ear infections. It is quite common for people to share their headphones with others. Sharing headphones with others is not a good idea since the bacteria from other people’s ears will travel to your very own ears and this will cause ear infections. Therefore, the next time you think of sharing your headphones, think again. Do not share your headphones with anyone, not even your friends or family.

Listening to music together is another way headphones cause ear infections. As romantic as it may seem, there are dire repercussions to sharing headphones. In the process of enjoying music together, you will end up transferring somebody else’s bacteria to your ears; this can lead to ear infections. Make sure you sanitize your headphones by thoroughly cleaning them with a clean tissue paper before plugging them in.

Apart from the germs and bacteria you get from borrowing or/and sharing headphones, you can also get germs and bacteria from not changing your very own headphone sponges. It’s recommended you change the rubber or sponge cover of your headphones every 2-3 months mainly because they tend to get covered with germs and bacteria over time.

Some other ways you can avoid ear infections caused by headphones is by always keeping your headphones clean, regularly replacing the old headphones and ear pads, avoiding sharing headphones or using the public headphones, and not sharing earbuds. Also, if your headphones have a sponge or a rubber cover, make sure you change them every 2 months. Finally, remember to give your ears some rest once every 15 minutes, and do not play the music way too loud, for this might contribute to hearing loss.

Extreme conditions no match for latest motorola solutions radio

We all know that Motorola produce the best two way radios and claim to be best in class, that can be backed up, by just using their products. This article (original can be found here) focuses on radios for the fire service, but as we all know they are well adapted for the police, ambulance and search and rescue teams.

Motorola Solutions (NYSE: MSI) continues its legacy of designing best-in-class digital radio solutions for firefighters and other professionals who face extreme conditions with the introduction of the APX 8000XE two-way radio and APX XE500 RSM. The newest entries into Motorola Solutions’ award-winning APX portfolio of Project 25  (P25) digital radios have been developed using the company’s well-established practice of hands-on research with firefighters and other first responders who need the most reliable mission-critical communications to do their jobs efficiently, effectively and safely every day.

The APX 8000XE features all-band functionality and is a rugged P25 two-way radio that can be used in either analog or digital mode across 700/800MHz, VHF and UHF bands. Time is of the essence for firefighters and they can be ready in moments by programming the radio remotely via Wi-Fi and radio management software to operate securely on different radio networks, allowing them to quickly help neighboring counties during large-scale emergencies.

Motorola Solutions works closely with firefighters and other radio users to find out exactly what they need and the APX 8000XE is the latest example of that thinking. It features the trusted ergonomics of the APX XE radio series, designed for easy operation in harsh conditions. The right-sized radio has a large top display, exaggerated controls for gloved hands and a dedicated push-to-talk button. It also provides best-in-class audio with a 1-watt speaker, three built-in microphones and automatic noise suppression for clarity in the loudest of environments.

“The APX 8000XE is an all-band rugged and submersible portable radio made for firefighters,” said Lieutenant David Hudik, Elgin, Illinois Fire Department. “With Wi-Fi access, we can reprogram the APX 8000XE on the fly when we are providing mutual aid assistance out-of-state.”

Most firefighters use a remote speaker microphone with their radios and the APX XE500 RSM is designed specifically for demanding environments, whether combating a fire or providing medical services at the scene of an accident.

– With five strategically placed microphones and automatic noise suppression, the APX XE500  provides clear communications when worn on either shoulder, center chest, or over the shoulder

– It can be submersed in 2 meters of water for up to 4 hours

– It withstands heat conditions of up to 500°F (260°C) for up to 5 minutes

– A channel knob automatically controls the channels of the user’s portable APX radio

“With the APX XE500 RSM, I can completely control my APX radio without having to hunt under my bunker coat for it,” said Lieutenant David Hudik, Elgin Fire Department. “With improved water porting, you can carry the APX XE500 upright or upside down for fast water drainage while maintaining clear voice communications.”

“Customer input is essential to our design and the Elgin Fire Department was right at our side as we tested the capabilities of the APX 8000XE and APX XE500 RSM,” said Claudia Rodriguez, vice president, Devices Product Management, Motorola Solutions. “The latest XE radio means firefighters will be able to talk with other first responders at the scene and across municipalities and regions. The new rugged RSM means they can communicate clearly in the loudest fireground environments, including blaring horns and wailing sirens.”
