The deer hearing is not the problem. They can hear an oncoming car or bike with loud pipes or motor just fine, at least as well as we can. It's their vision that's not great, as they have virtually no depth perception and are prone to run right out in front of something because they can't tell how fast it's moving or the direction. Not sure how a sound device is going to fix that.
Some of my riding friends run electronic deer whistles on their bikes and get a false (in my opinion) sense of security from it, and run 70 mph on highways where the thick trees come right up to the road. I can't help but think it might be making them more, not less, susceptible to a catastrophic event with a deer.
It would be awesome if these things work, but I'm having a hard time imaging them on the 5,000 miles of road in just my state alone, which is thick with deer from stem to stern.
