In researching that, I found a lot of expert opinions that a Deers hearing range is basically the same as a human being. In a nutshell, it was found conclusively that common Whitetail Deer hear sounds from 500 to 12,000 Hertz, and, at elevated volumes, sometimes as high as 16,000 Hertz, but never beyond that. Since the absolute top end of a Deers hearing range is the same as the advertised absolute low end of the frequencies generated by a Save-A-Life Deer Whistle, the chances of a Deer actually hearing and reacting to one of these devices is virtually non-existent.
