Offering workers hearing protection options

Much Like Protecting your sight or looking after your health, your hearing should also be protected, this article tackles hearing protection within the workplace and what type of earplugs are best, Enjoy.

OSHA regulations dictate we offer a “variety” of hearing protectors to noise-exposed workers. What is best practice for providing a variety while keeping inventory to a minimum?

Per CFR 1910.95(i)(3), “Employees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors provided by the employer.” But does “variety of suitable hearing protectors” mean two or 10, earplugs or earmuffs, different colors or different sizes?

The wrong approach is to choose a variety based on factors that have no effect on protecting hearing, including the published noise reduction rating. Some safety managers offer several different large foam earplugs that are yellow, green and orange â€" mistakenly assuming they meet the “variety” requirement and not realizing that a significant portion of their workforce will never achieve an adequate fit with a large foam earplug. In those cases, their supposed “variety” actually limits the number of workers adequately protected.

This bad assumption is often codified into company safety policies that require a minimum NRR: “Approved hearing protectors must have an NRR of at least 32 decibels,” or similar criteria. By definition, that typically means a large foam earplug. Despite the higher NRR based on 10 laboratory test subjects, workers with smaller ear canals will never achieve an adequate fit with those large foam earplugs to stop noise-induced hearing loss.



What are the factors that affect good fit of an earplug?



  • Size: Like a cork in a bottle, an earplug that is too large or too small will never achieve an acoustic seal to protect hearing. Offering a variety of sizes significantly improves the percentage of employees obtaining a good fit.


  • Shape: Ear canal openings may appear round, oval or slit. A foam earplug often fills an oval or slit opening better than pre-molded earplugs.


  • Ease of insertion: Some workers have difficulty rolling or inserting foam earplugs due to lack of mobility. For these workers, an earplug with a stem may be easier to insert.




Based on thousands of fit tests administered to workers in the field, the following four earplug styles provide a selection that would adequately protect nearly every worker:



  • Large foam earplug


  • Smaller foam earplug


  • Large reusable earplug


  • Smaller reusable earplug




The good news is that offering a variety does not necessarily increase cost. Buying 1,000 earplugs of one style or 250 earplugs of four different styles is fairly equivalent in cost. But the bigger variety significantly increases the probability that more workers will be adequately protected.

Many worksites adjust their inventory based on results of their fit-testing of hearing protectors. By reviewing which earplugs repeatedly provide the best fit, these companies identify the gaps or duplications in their offering and can adjust accordingly. Sometimes, this means adding a smaller-size earplug, but many times companies find they can remove some less-effective earplugs from their inventory. It’s not necessary to carry a dozen different earplug styles.

Finally, any offering of hearing protection needs a hands-on training component. How can a workers determine whether their ear canal is large or small, round or oval? It’s impossible to view your own ear canal opening in a mirror. A quick glance by a safety trainer can be of tremendous benefit in helping workers select the right earplug the first time.

Those New Tracks You’re Listening to Are About to Sound Much Better

SO you’re walking down the street and suddenly the music kicks in, you drop to the ground and pull your earphones out of your ears! “what just happened” you think, then you realise the un-pause on the mp3 has just kicked in and you forgot to turn it down. Well people this will be a problem of the past with these earphones, Now all I need them to do is make coffee. VERY IMPORTAN You can find the original article here

What’s been your favorite set this weekend? Or the best new track you’ve shared with all of your friends? Well take that track and imagine listening to it in exactly the way your ears want you to.

Meet the Even earphones, who tune themselves to each person’s particular hearing. At just under $100, they customize the sounds they play to suit your own audio needs. They use their own EarPrint technology that measures how you hear different frequencies, then sets the earphones to play back sound specifically for each ear. As a result, the headphones give you a profile tuned to your own ear (each ear with its own profile).



One of the biggest things that originally drew me to the earphones was the fact that they are not a pre-order campaign â€" they have physical earbuds available now. The company, who launched in in June, has sold out batches twice thus far and are continuing to take orders on their website. Luckily, I was able to get my hands on a pair to try out as well.

I’m pretty picky about the gadgets I use for audio, as I’m constantly listening to music â€" digging for new sets on Soundcloud, reviewing new tracks, jamming out in my own world. Being able to plug in and listen to my own music is what allows me to focus and, as a result, I’m very specific about the type of earphones or headphones I use. That being said, I was overly ecstatic when I was handed a pair of Even earphones to try out.

First, their appearance: the cords are a high-quality string that have a smooth look and feel. The buds look sleek, with a simple black-and-white color scheme â€" one black, one white, with the EarPrint device hanging at the middle of the cord, meant to dangle at your chest. They don’t tangle easily, which makes them easier to carry without having to worry about dealing with knots. They’re the type of earphones I wouldn’t mind wearing out in public.



Next: the sound test. This is where we meet “Sarah,” the soothing female voice that guides you through a number of sounds to test where your hearing level is at. This test was very straightforward â€" Sarah literally starts by saying “Hi, this is really easy” â€" and felt very conversational as she talked you through each noise. Five pieces of music are played for each ear, and you’re required to hit the button once you hear the sound. Though the process takes a little bit longer than I’d like, it’s seamless.

Overall quality of the listening experience was great. I switched between my Bose over-ear headphones and the Even earphones to test the difference in sound quality and worked to try a few subgenres of electronic music to see how each would sound between both pairs. I started off by listening to Louis The Child’s set from Lollapalooza this year and instantly found that the vocals were much more emphasized than in my Bose headphones. Next, I moved on to Mikey Lion’s live set from Desert Hearts 2016 and loved the emphasis on the bass I was hearing â€" the Even earphones made it much more of an all-around experience. I then switched over to Troyboi’s tracks Do You? and O.G. to continue to test this bass theory and, again, Even delivered.

As my hearing is likely damaged based on the amount of festivals and shows I’ve attended over my lifetime, it was much appreciated that the earphones were able to pick up on the frequencies I have more trouble hearing to create the full experience tracks deserve. Interestingly enough, every time I switched back to my Bose headphones to compare, I had to turn the volume down because it came at full blast and was overwhelming â€" and, when I did, the clarity between vocals and bass was lost. All in all, these babies pack a punch with their sound quality when it comes to electronic music.

It’s refreshing that these earphones don’t require using an app, since that seems so commonplace nowadays. All of the information that goes into your profile is saved in the little box hanging onto the string, so you can plug them into any device â€" phone, laptop, iPod, whatever you want â€" and still have your own profile saved. I found this extremely helpful, as it meant that I don’t have to re-adjust my volume based on what device I’m using. Beyond that, it’s a refreshing change from listening to sets with friends and having to change the volume based on everyone’s sensitivities. It makes listening much simpler and, quite frankly, electronic music better. How could you say no to a custom-made, surround-sound system in your own ears?

To get you started, here a few sets, old and new, you may enjoy listening to in the earphones (ok, to be fair, these are sets that I would want to hear in them):

Motorola Solutions’ digital two-way radio technology enhances mission-critical communications at Munich airport

Motorola solutions are a company well known for their robust two way radios and for building world class communication structures. Improving on the current TETRA system with an IP dispatch console and piloting the WAVE system, that allows a phone app to connect to the radio system, for communicating of site. You can read more about what Motorola are doing for Munich below and you can find the original article here.

Motorola Solutions has received an order to implement a comprehensive update and extension of its existing TETRA digital two-way radio system at Munich Airport.

The newly modernized communications infrastructure ensures greater connectivity, interoperability and collaboration between various business and operational functions at Germany’s second largest airport. Motorola Solutions will also provide services for ensuring smooth operations.



Within the framework of the TETRA radio network refresh, Motorola Solutions is equipping the airport with a new MCC 7500 IP Dispatch Console. The comprehensive, scalable solution enhances the IP architecture to ensure optimum call set up and availability. It will also allow Munich Airport to expand its communications infrastructure in the future without interrupting existing services. As well as this, Motorola Solutions will implement two TETRA base stations for improved TETRA radio coverage in the terminal buildings.

Alongside the improvements to the TETRA system, the airport has started a pilot project for the potential introduction of Motorola Solutions’ broadband push-to-talk (PTT) platform WAVE. The goal of the installation is to ensure that airport staff can communicate, no matter which device or infrastructure is being used. The powerful PTT solution WAVEâ„¢ Work Group Communications provides airport authorities with secure and reliable communications beyond TETRA radio â€" including broadband devices and networks â€" to enable greater workforce connectivity, interoperability and collaboration. WAVE connects the TETRA system used by administrative staff with service management employees who join the broadband platform via smartphones, computers, other radios or telephones, meaning that staff across the airport can communicate with one another from virtually any location.

“We have been working with Motorola Solutions’ TETRA two-way digital radio system since 2007,” said Michael Zaddach, head of the IT service division at Flughafen München GmbH. “The update of our TETRA infrastructure enables us to further improve our communications in airport operations and make our processes even more efficient.”

“We are collaborating closely with Munich Airport to provide a future-proof TETRA digital two-way radio network,” said Klaus-Dieter Drossel, sales director for key accounts, Motorola Solutions Germany GmbH. “We are also pleased that Munich Airport is testing our broadband push-to-talk platform WAVE, and we are certain that it will enable airport staff to work together more closely, no matter which device or network they use.”

Exactly what does earpiece mean

Almost all adults have used an earpiece at some point in their lives. An earpiece is actually a gadget placed on the ear and is usually used for listening to something. Millions of people normally use an earpiece for different reasons. In this article, we are going to explain in details different uses of an earpiece.

The first very common use of an ear piece is connection to a wireless radio. Wireless radios usually consist of earpiece cable that usually connects the radio to the user. This is very common especially in sports such as cricket where people usually follow the game from the radio. The earpiece is usually plugged either on a single ear or both ears.

Stethoscope is a type of earpiece that is mostly used by medical practitioners. This earpiece is a bit different from the normal ones and it needs to be carefully inserted into the ears so as to provide an excellent acoustic seal as well as make the user comfortable. This type of earpiece usually snaps firmly to the ends of the ear tube and requires special skills in order to safely remove them after use.



An Earpiece is also used as a hearing aid. This type of earpiece is either made from plastic that has been well molded to fit the exact shape of your ear or with a thin plastic dome known as open fitting that is usually fitted inside the ear. This type of earpiece is available in different categories and its suitability usually depends on the user degree of hearing loss. It has a microphone that fits behind the ear as well as an earpiece that perfectly fits on the ear. Custom made earpiece usually differs slightly from the normal earpiece in that it is usually made from a clear plastic known as NHS behind the ear hearing aids.

Did you know that an earpiece is usually used on 2 way radio? The radio earpiece is available in variety of styles. Some of the styles include D-ring, clear tube and over the ear. Earpieces for two way radios are usually used on many different radio brands including Kenwood, Motorola, Icom and Binatone. In addition to that, it is also used by bar staff, door supervisors and security staff.

Most people usually wonder how TV presenters communicate with the producers. Typically Presenters use an earpiece to receive instructions or information from the director. They can also receive messages from a device that plays a recorded script. A Presenter earpiece is available in two categories: wireless ear bug or tube earpiece. These types are usually very small and cannot be seen unless you look keenly for them. They are used by all type of presenters either in studio or out in the field as well as those in live broadcast and entertainment field.

Thousands of people use earpieces to listen to music on their phone IPod and mp3 players, They are also used to communicate on the phone. Typically, an earpiece usually fits both ears and the style that is commonly used is white. They are also used by sound engineers, musicians, audiophiles to listen to their own vocals, music, and stage instrumentation during live performance or when recording studio mixing. In most cases, the earpieces are usually customized to provide comfort and noise reduction from the surrounding to the user.

So the big question is, what is the difference between an earphone and an earpiece? The main differences between these two devices are; an earpiece a speaker is near or inside the ear while the earphone is a traducer that converts electric signals to sound and it is usually held near the ear. An earpiece has both its pros and cons. Some of the benefits of the earpiece include being lightweight and portable. It is also small in size and cannot be seen easily. Common disadvantages associated with earpieces include not being able to filter external noise properly and having problems receiving sound from them especially if there is a lot if background noise.
