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.

As promised

They do the job.  Amazing how well they amplify and suppress at the same time.  My only complaint is the tiny batteries are recommended to be removed after each use and my thumbs and fingers cannot grip them;  I can only extract them with needle-nose pliers.  But that’s a small issue. I bought tiny pliers and added them to the kit.

Perfect earplugs

I have only used them once so far on a crow hunt but they are amazing. Never used hearing protection for hunting but I'm glad I bought a pair helps protect the ears and they really are amazing. Only thing is I wish they had a on/off button instead of having to take the battery out to turn them off. ONLY DOWN FALL

Release the software

Received them programmed based on hearing test I took. Put them in. Couldn't understand others in the blind. Wouldn't it be cool if you released the software and I could program them myself? iHear Medical does this. I was told to send them back in so adjustments could be made. Meanwhile the 30 day return window is getting smaller, I don't have them for the hunting season, and they would probably be sent back to me without much improvement, if any. Hard pass. Just let me program them myself.

It did good as far as hearing birds and quieting down the gun shots but it hurts your ears. I tried changing out the ear inserts but still pretty painful to wear. By the end of the day i could hardly move my ear to get them out. Was hoping after a week of hunting my ears would get used to them but it hurt about the same every day.
