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.

They work

I've used them 6-7 times, ranging from 1 hour to 4 hours of continuous wear. So far I like them a lot. Time will tell how the battery holder will hold up. That is my only concern as of now.

Going back to basics

They all fall out my ears all the time. No matter what size I use. Every 5 minutes I have to readjust. I just recently lost one because it fell out my ear hunting.

Should be required for all hunters

Unbelievable, I could hear and “key” protect my hearing while in use. Wish I could have had a pair sooner.

Worth every penny!

Experience was great however halfway through my hunt they wanted to pop out of my ears. If you’re not careful they can fall out and you won’t feel it. I strongly recommend using the lanyard! They come with one and mine was missing when I first got it. A quick email later and they sent me it right away! Not only a great product but great customer service as well. I’m a profesional hunting guide and I’d love to work with Tetra and endorse their product to my clients!

Alpha shield 90’s

Great product from start to finish. Asked several questions on the home page and received immediate and pertinent info on product. Quick and easy purchase and received the product within 5 days of order. Would highly recommend alpha shields to any waterfowl hunter looking to invest in a pair of hearing protection.
