For years, manufacturers have expected hunters to take a “one-device-fits-all” approach to hearing protection and enhancement. As hunters ourselves, we know that doesn’t work. The sounds we need to hear on the range or in a duck blind are completely different from those in the turkey woods or deer stand. No two hunts are alike, and your hearing protection shouldn’t be, either. Whether your passion is calling in mallards, flushing upland birds, smashing clay targets, running and gunning a big ‘ol tom, or waiting patiently for a trophy buck, TETRA is dedicated to protecting your hearing, while helping you “Hear The Hunt.” 


At TETRA, we used our patent-pending Specialized Target Optimization™ (STO) to isolate and enhance the exact frequencies hunters need to hear for a variety of pursuits: deer, elk, turkey, waterfowl, range, and upland. We took those frequencies and created custom programs to enhance the sounds you most need/want to hear - like duck calls, gobbles, and voices - and protect you from those you don’t. Now, with our multi-pursuit device, you can get all the custom programming in one convenient device, and changing between programs is as easy as one simple tap.

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

  • Extremely comfortable to wear all day

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, and the sounds of the game you are pursuing are all easily audible.

Tetra AlphaShield Multi-Pursuit

6 Pursuit-based programs in one device

  • Waterfowl Boost
  • Turkey Boost
  • Upland Boost
  • Deer Boost
  • Elk Boost
  • Clearcomm

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 Multi-Pursuit exceeds expectations

I purchased the Alpha Shield Multi-Pursuit before my September Sharptail grouse hunting trip to MT. I wore them for seven days of hunting and they are the most comfortable hearing devices I have ever used. They really reduced the gun noise and enhanced my hearing as advertised. In October, I hunted pheasants in ND in an early winter storm-8 inches of snow, strong winds and temperatures in the teens. The Alpha Shield wind noise reduction worked well and it helped me pinpoint the roosters flushing in the cattails.

Very satisfied customer

Used skeet shooting before hunting season. Worked extremely well. Comfortable fit, blocked the noise from the shot but allowed normal conversation. Very satisfied with the product.
