Protect and hear at the range.

Competitive and recreational shooters need quality hearing protection to maximize enjoyment and safety. Shooters also need to clearly hear their surroundings, shooting partners, instructors, and students. TETRA products were designed by hearing doctors and lifelong shooting enthusiasts to provide you with the most premium hearing experience on the range. With our industry first, patent-pending Specialized Target Optimization (STO), unsafe sound levels are reduced, but voices are accentuated for maximum audibility and clarity. TETRA AlphaShield products offer the most comfortable and best sound experience available for shooters.

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 environment. WIth our AlphaShield Range products, STO provides clear voices for your shooting partners and range officers, while maintaining natural levels of sounds for the environment around you.
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, 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.


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.
