In case there is any confusion, let’s set the record straight: duck hunting with unprotected ears causes hearing loss. As hearing doctors at TETRA, we see what years of waterfowl hunting does to our patients. Recent studies show that people with hearing loss are more likely to develop dementia, Alzheimers and other chronic health problems.* Hearing loss impacts overall health and wellness, and ruins the hunting experience.

So why do 86% of hunters NOT use hearing protection? Previous products have distorted the sound of the call, either over-amplified everything or blocked out your surroundings, and just weren’t comfortable. We solved those problems with the TETRA Shield Series. Using our patent-pending Specialized Target Optimization (STO) voices and calling are clear and natural while AlphaShield Compression reduces loud sounds to safe levels.

AlphaShield is a small, extremely comfortable, one-size-fits-all solution. AlphaShield provides great comfort and great protection without the need for an ear impression.

Our Technology

Specialized Target Optimization

Our hearing devices feature patent-pending Specialized Target Optimization™ (STO). STO is the world’s first hearing technology that isolates and enhances the exact frequencies needed to improve hearing for your specific hunting environment. With STO, voices are clear, calling sounds natural, wood duck squeals, whistling wings, and mallard drakes are all easily audible.

TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment it’s needed. For more sustained loud inputs, like loud calling, AlphaShield Compression® limits the overall output to a safe level, then returns to normal amplification once the loud input has stopped. Never miss a sound you want to hear, and protect your hearing for life.

ClearComm™  is our proprietary algorithm that accentuates human speech while minimizing noises and distractions that occur outside of the frequency range of human voices. ClearComm is useful for better understanding speech and whispers of hunting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

Research

Hearing and the Brain

Research at Johns Hopkins University suggests that more hearing loss increases the risk of dementia. In one study, people with hearing loss were 24% more likely to have Alzheimer’s.* 

With hearing loss, our brains have to work much harder to make sense of what is being said, and even harder to filter out speech from unwanted background noise. Simply trying to understand conversations requires more mental energy and concentration. 

If basic conversations take up most of our mental energy, there is less opportunity for our brains to sort out and store other information. 

At TETRA, our goal is to minimize hearing loss for hunters and shooters, because research shows if we reduce hearing loss, we can also reduce the chance of getting dementia and Alzheimer’s.

Best I have used

I suffer from tinnitus and have tried a number of different electronic hearing protections for hunting. I can say with certainty these are the best. I took them to Spain on a driven partridge hunt and even after 600 shells in two days I did not notice any increase in the ringing. Would recommend to anyone who takes hearing protection seriously

Can't say they were worth it

I gave them a full season before reviewing them. They do what they are supposed to but I'm not impressed with them. It's still pretty difficult to hear conversations in the blind and they are not nearly as comfortable as I would have hoped. I had to take them out and give my ears a break about every half hour. They do not cancel wind noise which is a pain as well. For the price, I am not impressed with the warranty either. They get two stars because my ears don't ring when I get done with a hunt. Which I could have accomplished with a pair of foam plugs.

Comfortable.

I've been hard of hearing for many years now due to shooting without hearing protection many years. I now wear hearing aids around my wife and others. They are not like natural ears but help me stay connected. The electronic ear muffs that are out there are not comfortable and "hot" during warm seasons. Tetra has now helped me find something comfortable that will boost my hearing of the geese in the distance and locating what direction they are coming. The shots from duck blind partners are of no consequence. A big "thumbs up"!

In desperate need of these

As with others, years of hunting w/o regular protection, along with a few to many concerts, has lead to excessive hearing loss. Long story short, after trying other lower cost options I decided to bite the bullet and spend the money on these. They are comfortable enough for hours of use and they added a tether by request and it is a needed upgrade. I was very happy other than the voices of other hunters very well, but ambient noises were enhanced and no issues with calling with them in. I’m in the process of sending them back for reprogramming and hoping that will help. These are a good purchase and worth the money (assuming reprograming will fix my issue). I’m not sure that I had my volume set correctly so my issues may simply have been user error on my end. I will update my review if possible, but as of now I still recommend them… but buy theses, or something else, before you have hearing loss and you will be better off in the long run. You simply can’t understand how important hearing protection is when you are young and bulletproof but it will catch up with you sooner than you think.
