Clear communication and environmental awareness are an absolute necessity on the range. At TETRA, we’ve analyzed the most critical sounds for the competitive and recreational shooter and programmed those into each device. Using our proprietary Specialized Target Optimization™ technology, range commands, instructors, students, and voices of shooting partners are clear. Surrounding environmental sounds are natural, while maintaining appropriate hearing protection for the shooter.

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 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.

All of our products use advanced digital processing to instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer protection based on the fit of the device. 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 talking with shooting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

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.

Superior Comfort and safety!

Growing up shooting guns I always dreaded having to wear ear protection. As I got older I found myself using ear-pro less and less because of the problems with conventional ear-plugs all outdoorsmen know far too well. Tetra's astounding comfort is unlike any other ear-pro, making hunting and shooting safer and all around more enjoyable.

A change in hearing protection

I have been shooting guns for a long time and have tried many different hearing protections, and none have compared to how well these work. While you’re not shooting it sounds like your regular hearing with no static or wind noise, but it completely cancels out the gunshots. A truly great product for any person that hunts and shoots!


A shooters simple solution to hearing protection

I've been shooting a shotgun for as long as I can remember, and have had my ears rung while afield more times than I'd like to admit. I've always known I should do something about my own hearing protection, but have never taken it seriously. I spend a good amount of time in the duck blind, and I've never cared for the foam inserts - especially when calling ducks. The few times I did look into advanced hearing protection, the options available were as much as new shotgun or two! With the introduction of the Tetra line of hearing protection products to the outdoor & sport shooting markets, we as a community of outdoorsman now have a viable option to consider. I've used the AlphaShield Range during shooting season as well as in the field. Once you get acclimated to the 'new normal' of what things sound like with the protection in your ear, it's really quite enjoyable. It feels good to know you're taking care of yourself while not giving up any critical part of the outdoor experience. I personally know one of the founders of this company, and this brand of hearing protection is an avenue where his two passions collide. You can trust this company has done the research to provide the outdoorsman with a quality product at a fair sticker price. It's exciting to see Tetra change the way we as an outdoor community view hearing protection for ourselves and the next generation. Give the experience a try. You won't regret it!
