Ok Guys something for you to sink your teeth into;

I’m an aerospace test engineer so for me this stuff comes naturally. As and off-season project I’m going to record in a sound studio the sound my bow makes at release without any string silencers. Then I plan to go through a test matrix putting different brand silencers at different locations on the Bus cables and String and attempt to tune the release noise. The question for all you experts out there is, what frequency range (not distance) can deer hear? And what’s your opinion about which bothers or makes them flinch/jump more, high frequency or low frequency?

Lrac,
Sounds like a great idea. I tested various stabilizers out last summer, using a digital sound meter. I was outside, though, not in a sound booth. Be sure to post your findings. I' ll do a little reading, and see if I can find the info on frequency for you.

My guess is that deer hear more prevalent in the lower frequency ranges. Some large animals like elephants communicate over serveral miles distance by using extremely low frequency sounds (lower than humans can hear). Most of the sounds the deer make are not the loud squeeling pig type sounds but lower freq type sounds like grunts and bleats, although some younguns tend to make higher pitched sounds.

I think your research should be directed into what types of sounds or at what most common frequencies are deer frightened/alerted. Then what types of movement do we as hunters do that creates sound in those frequency ranges and how can we minimize them.

If only I could build a bow that sounded like a doe bleat when it went off.

If you go to quiet-tune.com and select the " decibel tests" button, you will find the following information:

" After much research, we found a test that was done on the hearing range of the whitetail deer. This study was conducted at the College of Veterinary Medicine at Texas A&M University by Dr. Ken L. Risenhoover, Dr. Jon Hunter, Roy Jacobson, and Glenn Stout. Their test results showed that the whitetail deer has a peak hearing range of one (1) to eight (8) kilohertz in the forty (40) to eighty (80) decibel range.


Hope this helps.
