No more dead batteries
By the staff of Trucks & Guns Magazine
How many times have you gone out to the range only to find that your battery powered hearing protection was left on and now has dead batteries? Not really the end of the world, but it is annoying. Well, what if there was a set of hearing protection that would allow you to hear normal volume tones like speech but block out high decibel (DB) sounds, without batteries? Guess what, there is and we are going to show you them right now. The Otis Technology Ear Shields block out gunfire and other high DB sound while still allowing low DB sound to enter the ears.
HOW IT WORKS
The Ear Shield uses sound reduction chambers to reduce DB levels without the use of electronics. Just like water and electricity, sound waves travel the path of least resistance. High DB sound waves get diverted through the sound reduction chambers while low DB sounds pass through easier. If you could see sound waves, high DB waves are larger and closer together so they get trapped and bounce around in the sound reduction chambers, reducing the overall DB levels. As you would expect low DBs are the opposite: longer, smaller waves that pass through the chambers easier, reducing their sound levels much less. The end result is that you can hear low DB sound almost unmodified and high DB sound are reduced to safe levels.
BEYOND NO BATTERIES
The Otis Technology Ear Shields have more advantages then just not requiring batteries. They are also much lighter in weight than standard ear muffs, allowing them to fit more comfortably for longer periods of time. On hot days they do not sit against your skin building up sweat, they fit out away from your face. This is also great for eye protection, no longer will you have your hearing protection pushing your glasses into the side of your head. The low profile design of the Ear Shields means that they will not interfere with cheek wells when shooting long rifles. They are adjustable to fit any size shooter, and they work great, available in two different DB reduction levels, 26 DB and 31 DB.
Compact, folds up small, more comfortable than large ear muffs and are under $25? You can’t go wrong. Our first thoughts were they felt fragile but the plastic they use is actually very durable. We have been using them exclusively and heavily for over six months now and have not had any issues. If they did break they are priced so well that picking up another set is not going to break the bank. They allow us to hear normal conversations without removing the ear muffs and reduce high DB sounds to a comfortable level with no electronics is great. We will be using these for a long time.
