Hearing protection devices (HPDs) help to reduce the amount of sound energy being transmitted into inner ear and protect ear against hazardous noise. Hearing protection device prevents people from occupational hearing loss due to operational or presence of noisy equipment such as stone saws and rock drills in the work place. It also prevents from non-occupational hearing loss due to recreational activities, loud music and fire arms. Hearing protection devices are of many types such as earplugs, earmuffs, hearing band, canal caps and uniform attenuation earmuffs. A good hearing protection device has various characteristics such as good seal, comfortable to wear and leads to effective communication. Shape and size of hearing protection device varies according to individual’s comfort, size of ear canal and environmental conditions. Hearing protection devices are used while working in industries such as gold mines, manufacturing sites, construction, forestry and pharmaceuticals. In addition, working in military can also cause hearing loss as some weapons are so loud that can cause immediate total loss of hearing. Therefore, hearing protection devices are required to protect a person from hazardous noise exposure. Hearing protection device helps to reduce tinnitus-ringing in the ears. They can also prevent person from fatigue and irritability.
North America has the largest market for hearing protection devices followed by Europe. This is due to technological advancement, increasing awareness about noise pollution hazards and high disposable income in the region. Asia is expected to show high growth rate in the hearing protection devices market in next few years due to increasing prevalence of hearing problems and rising government initiatives in this field. Technological advancement, passing of health and safety regulations, rising noise pollution level and growing demand for user comfort devices are some of the key factors driving the growth for global hearing protection devices market. In addition, their easy use, low cost and increasing consumer health awareness about noise hazards are driving the hearing protection devices market. However, manufacturing with lesser noise and off-shore manufacturing are some of the major factors restraining the growth for global hearing protection devices market. Ongoing innovation in hearing protection devices would develop opportunity for growth of global hearing protection device market. Rising number of mergers and acquisitions among companies and increasing focus on style, fashion and aesthetic appeal are some the major trends that have been observed in global hearing protection devices market. Some of the major companies operating in the global hearing protection devices market are Honeywell International Inc., 3M, ADCO Hearing Products, GN ReSound, Centurion Safety Products Ltd, Amplifon, Delta Plus, Elvex Corporation, Hellberg Safety AB, Moldex-Metric AG & Co. KG., Siemens Audiology Solutions and Sonomax Hearing Healthcare, Inc. As this article shows, Hearing protection devices are an important part of a lot of peoples working lives, protecting peoples hearing is a very important part of health and safety legislation.

The use of 2 way radios on a construction site is the best way to achieve efficiency by saving time, increasing productivity, and enhancing workers’ safety. A Two way radio device allows workers on a construction site to communicate with each other instantly. The radio is incredibly instrumental where the site manager has to communicate to hundreds of workers spread across a large contraction site. On a construction site, workers are always moving around carrying heavy loads and operating machinery. The working environment requires heavy-duty communication devices such as the 2 way radio models. The radio ought to have the same specifications as the radio military personal. These features include shock resistant, water, and dust resistant to guarantee durability for up to 10-15 years. These specifications ensure that the device can operate in harsh environments without spoiling.
A construction manager may need to reach out to workers on a crane, up a sky-scrapper, management office, and security personnel on site using a single network. The Two way radio enables construction workers to communicate over all these possible barriers and achieve clarity and reliability in communication. Whether, it is rainy or windy, the Two way radio will deliver top-notch communication efficiency. The noisy construction environment does not affect the clarity of the 2 way radios. The Two way radio helps improve the safety of workers while on a site . The radio can make emergency calls in explosive environments such as places with combustible dust or even flammable gas. The radio has an emergency alert features that sends instant distress calls, even when a worker is unconscious. For instance, Man Down features sends an automatic alert if a worker falls or the device stays in a horizontal position for a long time. There is also the Lone man function that ensures any worker isolated, in case of an emergency, has special communication options. During emergencies the radio adjusts its system by interrupting group conversations to allow the distress call to go through to the control centre. Such a function is critical to a situation where a worker is alone and in trouble. Using the 2 way radio guarantees a reduction in both operation cost and delays. Radio communication ensures that construction managers can pass urgent messages quickly to the different departments working on a site. If there are any changes in the course of the day, the manager does not have to call for a meeting or wait until close of business to communicate. The 2 way radio offers the perfect speed to communicate changes during construction work. The technology also saves on the cost of paying cellular charges if the company is using a mobile network to communicate on the site. Most radios comes equipped with GPS tracking that aid both security and efficiency. Site managers are able to locate the position of all workers using the communication device. Making it possible to track the movement of vehicles on site and the position of equipment such as forklifts, backhoes, and excavators. The GPS tracking functions also helps construction managers to improve on-site security by identifying where their equipment is. Since most construction workers will use a Two way radio device, communication is sure to improve deliveries to and from the construction site. In case of a vehicle breaking down, the control room can receive the messages and arrange for support without wasting time. The flexible nature of the 2 way radio network accommodates construction sites of different sizes. Whether it is a large construction company, a medium sized company, or a small contractor the 2 way network delivers. A big construction company can enjoy the increased calling ability using a single network. If multiple sites use the device, it is possible to have an integrated system that shares the same network but does not allow for interferences. The small contraction company can use a few radios on the single network and cut on cost. Therefore, it is possible to employ the services of the communication devices in different circumstances. Construction managers today are aware of the need for good communication in their sites. An efficient communication network ensures that everyday work is stress-free for the managers and the supervisors. Philosopher Albert Camus once wrote, “What I know most surely about morality and the duty of man I owe to sport”. It is hard to find a more fitting epitaph for Verne Gagne, beloved wrestling champion and influential promoter, who passed away in April of this year.
Verne, who was 89 years old, had been suffering from Alzheimer’s disease and living in a health care facility in Minnesota. However, it would be wrong to dwell on the saddening end of a life as successful and pioneering as that of Verne Gagne, a man who helped to shape the landscape of professional wrestling forever. At varying times during his life, Gagne was an NFL pro footballer (with both the Green Bay Packers and the Chicago Bears), an alternate for the USA’s Olympic wrestling team, a multi-time amateur wrestling champion, a US marine, a World Champion professional wrestler, a hugely successful promoter and a devoted husband and father. He trained, or helped to train, many of the biggest and most successful names in professional wrestling history, including future World Champions Ric Flair, Ricky ‘The Dragon’ Steamboat, The Iron Sheik, Bob Backlund, Dick The Bruiser, Sgt. Slaughter, Blackjack Mulligan and ‘Mr. Perfect’ Curt Hennig (father of current WWE wrestler Curtis Axel), as well as industry legends such as ‘Cowboy’ Bill Watts, Larry ‘The Axe’ Hennig (father of Curt), Blackjack Lanza, Baron Von Raschke, Jimmy Valiant, Ken Patera, Ole Anderson, Jim Brunzell and, of course, his own son, Greg Gagne. Verne Gagne’s story begins on a little farm near Corcoran, Minnesota. He was born in 1926, into a very different world than the one we live in today. As a child, Verne would sit on his grandfather’s lap and listen to wrestling on the radio, as there was no television. As Greg Gagne recalled in the WWE’s 2006 ‘Spectacular Legacy of the AWA’ DVD, it was during one such session that Verne announced his intentions to become a professional wrestler. Gagne’s amateur wrestling accomplishments speak for themselves, Verne was named the Northwest AAU Champion in 1942, Minnesota High School Champion in 1943 and ‘Big Ten’ Champion in 1944, 1947, 1948 and 1949. He was also crowned National AAU Champion in 1948 and 1949 and was selected for 1948’s US Olympic Team (although he didn’t compete). Gagne also won the NCAA Championship in 1949. As a promoter, Verne was famous for his emphasis on realistic, ‘scientific’ wrestling, a view that contrasted sharply with the then-WWF’s more cartoonish, family-orientated approach to the sport. After he turned pro, Verne Gagne became one of the first stars of the early TV era of wrestling, becoming the NWA (National Wrestling Alliance) Junior Heavyweight Champion in the process. In an era of more serious, credible and ‘straight-laced’ wrestling, Verne Gagne exhibited a special kind of charisma, which was backed up by his great work-rate and wholly believable matches. He was also among the first wrestlers to seek endorsements outside of the wrestling world, a move which paid off handsomely at the time and hinted at a high level of business acumen. Eventually, as Gagne’s popularity with wrestling audiences increased, he became frustrated at the NWA’s apparent unwillingness to allow him a run with the World’s Heavyweight Championship, at that time held by Lou Thesz. Later, when Pat O’Connor was World Champion, the NWA again refused Gagne a title run. Because of this, largely political, limitation, Gagne and his partner Wally Karbo purchased the Minneapolis territory and seceded from the NWA, taking several other territories with them and forming the bedrock of the American Wrestling Association (AWA) in the process. The AWA proved to be a successful venture and ran between 1960 and 1991. During that time, the company expanded outwards into traditional NWA territories, in a similar (albeit less aggressive) manner to the way that Vince McMahon Jr’s WWF would expand in the 1980’s. Vince Jr has even gone on record to say that if he hadn’t taken wrestling national when he did, Verne Gagne would have done so. Whilst still an active competitor, Verne drew criticisms in some quarters for constantly booking himself as the AWA World Champion, including one run that lasted from 1968 until late 1975 (he eventually lost the belt to Nick Bockwinkel). However, it should be noted that Verne was undeniably the promotion’s biggest star and that the company was effectively built around his star power. As AWA World Champion, Verne feuded with some of the all-time greats of pro wrestling, stars like Bockwinkel, Fritz Von Erich, Gene Kiniski and The Crusher. In the 1980’s, the AWA found itself going head-to-head with Vince McMahon’s WWF, a promotion which had been mainly built around the acquisition of Hulk Hogan, a man who had been the AWA’s biggest drawing card not long before. McMahon sought to dominate the wrestling industry by expanding his New York-based territory via cable television. Almost overnight, the AWA’s top talent abandoned Verne’s outfit for the greater exposure offered by McMahon’s WWF and the AWA suffered for a lack of credible main event stars. Despite this, Gagne’s AWA still offered a very different product to McMahon’s WWF. Where the WWF promoted bodybuilders and super heavyweight ‘big man’ bouts as its top attractions, the AWA was still offering classier, more traditional wrestling matches. Even under diminished circumstances, the AWA was still an important starting point for many wrestlers to polish their performances and ‘round out’ their ring work and personas. Over the years, Gagne’s promotion gave a start to many talents that are now regarded as legends within the wrestling industry, including WWE Hall of Famers Hulk Hogan, Shawn Michaels, ‘The American Dream’ Dusty Rhodes, ‘Superstar’ Billy Graham, Scott Hall, Jesse ‘The Body’ Ventura, The Road Warriors and even announcer ‘Mean’ Gene Okerlund, as well as many other stars including Big Van Vader, The Nasty Boys, ‘Mad Dog’ Vachon, Marty Jannetty and Rick ‘The Model’ Martel. The AWA hung on for as long as it could, but in the wake of the WWF onslaught and an ongoing legal dispute concerning some land he owned along Lake Minnetonka, Verne was effectively forced out of business, going bankrupt in 1991 and later selling his company (and its entire video library) to the WWF. Despite the ultimate demise of the AWA, Verne Gagne remained one of the most recognised, respected and beloved professional wrestlers of all time. In his 2013 book ‘The 50 Greatest Professional Wrestlers of All Time’, former ‘Wrestling at the Chase’ announcer Larry Matysik ranked Gagne at number 11, saying “As much as his ownership of the AWA leads to criticism that he was its champion, the reality of the promotion’s huge profitability for more than two decades demonstrates that the audience bought him as that champion. And AWA shows drew well even when Gagne was not working”. Gagne’s legacy as one of the greatest professional wrestlers of all time is already assured. By the time he retired, he was a 15-time World Champion (10 time AWA World Heavyweight Champion, 5 time Omaha World Championship), as well as a Champion in Japan. He was an inductee into the WWE Hall of Fame, as well as the WCW, Professional Wrestling and Wrestling Observer equivalents. In addition to his incredible in-ring exploits, Verne Gagne should also be remembered as one of the most successful wrestling promoters ever, as well as one of the best teachers the industry ever produced. For his talent, charisma and freewheeling entrepreneurial spirit, Verne will always be remembered as one of the very best. He was, to quote his son Greg, “a special man”. In simplest terms, the loop goes around your neck and the small earpiece goes inside of your ear. It is important, however, to ensure that the loop is well concealed, otherwise it can totally give the game away. Wear a high collared shirt or blouse in order to hide the loop around your neck.
The earpiece itself is usually flesh coloured (different shades and skin colours are available), but even if it isn’t, the earpiece is so small that people are unlikely to even notice it. The microphone needs to be positioned near to your mouth, but not so near that people can see it. Once again, a high collar will be of some service here, because you can place it underneath the collar line (spy earpiece microphones tend to be rather powerful for their size – but remember to test the whole setup first before you go into the field). If you happen to be wearing a tie, then so much the better, because the microphone can be easily clipped behind the tie (where it is very unlikely to be noticed). Next, take the loop (making sure that it is under your clothing) and ensure that you can easily access the battery, beeper button and any other attached gadgets. You can run the battery straight into your pocket, provided your shirt is long enough, or, if you’re feeling particularly clever, you could even cut a small hole inside of your jeans pocket and thread the beeper/battery through the inside of both your shirt and your jeans (this will also work for your phone). The hardest things to hide will be your attached cellphone or two-way radio. The cell can sit, quite happily, in your pocket (in fact, people generally expect you to be carrying one anyway), but the earpiece’s connection to the headphone socket must not be seen (keep it under your clothes, as discussed above). The two-way radio option is a little more difficult. Two-ways can be hidden on your belt (underneath loose-fitting garments), around your back (again, covered by clothing) or even strapped to your leg. It is definitely harder to hide a two-way, so it isn’t the ideal option for prolonged covert usage. Finally, we advise you to check the whole thing out in the mirror first. Make sure that outside influences such as wind, rain, pushy crowds or actions such as running to catch a train are not going to expose your subtle setup. If you think you are too exposed, try different permutations on the advice provided, until you find something that works for you. This is an extract from How to be Normal: A Guide for the Perplexed by Guy Browning. The extract was found on this website and centres around the bodyguard of the princess and the earpiece they use to communicate with a significant character.
MONDAYMarsha on reception is wearing a hat. That's unusual for three reasons. Firstly, she works indoors. Secondly, she normally takes very little interest in her appearance. Thirdly, it looks like the kind of hat you'd wear to a wedding or possibly the races. When I asked her why she was dressed up, she said it was a secret. I said if she wanted to keep a secret, it's probably best not to look like Dame Edna. She clearly didn't know who Dame Edna was so I lost the battle hands down and left her on reception applying her lipstick. She must have developed a peri-menopausal crush on a courier with a millinery fetish. TUESDAYSomething is definitely going on. David Eldridge, our operations director, normally wears a short-sleeved shirt with those weird buttoned sleeve turn-ups. I have no idea where you'd go to buy shirts like that unless there's some kind of Bureaucrat Surplus store somewhere. Today he's wearing exactly the same shirt obviously but with a bow tie. I managed to restrain my howls of laughter and asked him why he was looking so natty. He tapped his finger on his nose, which could have been an invitation to do a couple of lines of Charlie with him but probably meant that it was a secret. This was slightly galling as I am communications director of the company. We have several values around transparency and integrity, and I should know everything in the company down to a light cough in the mailroom. WEDNESDAYWe have an extraordinary board meeting today. I got in late because I was still trying to find out what the big secret is. There was one empty seat next to some woman I didn't recognise. I was about to sit down when this woman waved me away as if I was some kind of IT spod come to fix the projector! Just as I was about to fill in a P45 for her (which I keep on my person for just such an occasion) another young lady strode into the room and sat down in my seat. Once I'd repositioned myself, I suddenly recognised a member of the royal family. Not a big A-lister but definitely royal. While we were all staring at her, the other woman, who had some kind of communication device in her ear, stared at us. Close protection, no doubt. THURSDAYThe Princess is on work experience because the royal baby has shunted her off the civil list. I noticed when we were walking around that her bodyguard was receiving instructions through her earpiece, which she passed on to the Princess who then said something quite perceptive. I suddenly had one of my brilliant ideas. I popped down to the IT guys and had a chat with one of them who is a bit of an electronics buff. I bribed him with some brightly coloured cable and he hacked into the bodyguard's earpiece. We listened in to the instructions being given and, I wouldn't like to swear to this, but I'm pretty sure it was Her Maj on the other end. When the Princess was touring the marketing department and hearing all about digital marketing, we heard some choice language, which you wouldn't normally expect from Prince Philip, let alone his missus. FRIDAYToday's board meeting started off with our bewigged CEO Lynton Spivey attempting to execute some kind of curtsey. Even the Princess, who's probably seen a lot of those in her time, couldn't help giggling. I just sat back and waited politely. During the meeting, the Princess began to come out with all sorts of brilliant incisive ideas about increasing my budget for Corporate Comms and that some kind of large yacht would be a great idea for hospitality. Spivey was nodding and curtseying and I could feel my job getting infinitely more pleasant. Suddenly, the bodyguard took her earpiece out and for some reason looked straight at me. In the ensuing silence, the Princess made a few of her own suggestions, which were all embarrassing tumbleweed moments. Her bodyguard then hustled her out of the room. Bang goes my knighthood. Here we Identify the features of two way communication using two way radio, A two way radio is basically a radio that can transmit and receive. Two way radios are simple, convenient and affordable way to stay in close contact with your colleagues, family and friends. Most companies use two way communication systems as a primary source of communication between their workers due to the ease, promptness and convenience offered by this communication system. The following are some of the key features of a two way radio system and their benefits;
900 MHz frequencies It is essential to point out that radios that operate within this frequency are capable of effectively communicating both indoors and outdoors. This means that they can be used in factories and other workplaces as well as outside when camping or hiking. Most cordless phones also use this frequency. However, the best thing about two way radios that use the 90 MHz frequencies can be used by both individuals and businesses without a problem. Adjustable gain Most two way radios come with an adjustable gain feature. This feature allows the user to adjust the sensitivity of the radio’s microphone. This feature is also useful along with the hands free operation feature because it reduces the possibility of unintended noises triggering transmission. It also enhances the ability of the radio to pick up quite voices. Auto channel change This feature enables all radios within your group to change to a new channel. This helps in preventing interference from other devices. For you to use this feature, everyone in your group must have two radios that support this feature. In case one channel is not so clear you can simply change and use the channel with little or no interference. Backlit display Most two-way communication devices including radios have a digital LCD display feature that displays useful information for instance your current channel. This feature enables you to turn on a lighted display which makes it easier for you to read the information on the screen especially in dark or poorly lit areas. Channels A channel is a frequency on which two individuals using two way radios can communicate. Typically, there are 14 FRS channels as well as 15 GMRS channels. Two way radios that support both FRS (family radio service) and GMRS (general mobile radio service) have the capability of supporting up to 22 channels. This makes it easy for people to communicate with each other using these radios. However, to effectively communicate, all radios in the group should be set to the same channel. Battery Two way radios are mobile devices. This means that they are designed for you to move around with them. As a result of this, these radios operate on battery power. Most radios work with standard alkaline AAA or AA batteries. Other models include rechargeable batteries. For those models that come with rechargeable batteries, it is essential for you to always fully charge the batteries before using the radio for effective communication. Call waiting feature Just like the regular mobile telephones, two way communication radios also have call waiting feature. If you are already on a call, this feature allows you to receive a notification that someone is attempting to reach you. The latest models will give you an option of immediately accepting the new incoming call or simply reject the call and calling back thereafter. Call tones Call tones allows the user to alert the other radio users in the group that he or she wants to talk. It is similar to a telephone’s ringing that indicates that someone wants to talk or someone is calling. Most radios allow the user to select from a variety of call tones. Intrinsically safe Also known as IS, intrinsically feature is a protection feature or technique used for safe operation of electronic devices in explosive environments. This concept was solely developed for safety measures specifically operation of process control instrumentation in unsafe areas. This means that two way communication radios can be safely used in hazardous areas without the fear of exploding or causing harm to the user. In summary, from the above features and benefits of two way communication radios it is clear to suggest that, these radios are convenient, affordable and safe modes of communication that can be used in workplaces as well as at home. They can also be used outdoors during camping, hiking or simply enjoying a shopping expedition in town. |
