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.

 

TETRA isn’t just hearing protection, it’s hearing perfection.

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.

Alpha shield review

I am very pleased with the performance and would have no hesitation recommending it to fellow waterfowlers and sportsman that shoot shotguns a lot, very comfortable and reduces gun blast noise Similar to clapping your hands!

Great hearing pro. and enhancement!

I had the Sport Ears molded inside the ear models for 6 years. I found them lacking in volume and very fragile. I purchased the Tetra Hearing Custom 3 weeks ago and they are fantastic. Highly recommend, worth the $. I hope the Tetra repairs lives up to the product should I require in future,

arrest hearing loss

long time upland/waterfowl hunter hoping to stop hearing erosion. These hearing devices definitely reduce shotgun blast as advertised. I can hear the geese coming before I can see them so that makes them a winner for me. Regular conversation and noises are altered in their tone a bit. Kinda tinny is the best description I can come up with.

My first time using the product

Took these out to the range before waterfowl season starts, very impressed with the blocking of sound from the shot. Very interested to see the results when I throw calling into the mix, so far feel and comfort seem to be great, not sure there is an official off button so I take the batteries out after usage.
