Deer-Whistle Ineffective, Says Bioacoustics Researcher - November 18, 2002
"We tested them strictly from an acoustical point of view," explains Scheifele. He found that the whistles typically produce a signal either at a frequency of 3 kilohertz (kHz) or 12 kHz. Both, as it turns out, are problematic.
The hearing range of white-tailed deer, the most common species in the United States, is between 2 kHz and 6 kHz, so the animal is not capable of hearing the 12 kHz signal.
Although deer may be able to hear the 3 kHz signal, it is only 3 decibels louder than the road noise created by the car, so the signal is buried. Scheifele points out that the situation would be worse with additional traffic in the area or if the wind was blowing.
But, on the other hand, I stick a pickle up my butt to keep rhinoceroses away. "Well, that's just stupid" you say, "there are no wild rhinoceroses in North America.
"That just shows how well it works" says I.

have two of them under the nose of the bike.. have had many deer on the side of the road stop, lift their head and watch me ride by... haven't had any incidents other than that.... don't know if they are working or if it's my GUARDIAN ANGEL

I've been experiencing the same thing for about 2 1/2 years now.
). They do work and they are not a joke. Well worth the few bucks.
Deer whisles do work , but probably not how you think. They, or the ones I've experienced, freeze the Deer. Not scare them away. So, if they're attached correctly (they have to be a certaint distance from each other) the deer will freeze, allowing (MAYBE) you to stop or steer around and through them. I say THEM, because where one is, there's ALWAYS more around. I sure wouldn't really rely on them, and around here with MULE DEER (BIG SUCKERS) I ride very very carefully in the early mornings and late afternoons
