Silent Dog Whistle
You probably can’t hear a dog whistle because the frequency is too high. Dogs hear higher freqencies better than people do. That’s why dog whistles seem to be silent. High frequency sounds usual travel further than voices.
Dog trainers use dog whistles to get a dog’s attention. Some think different breeds react to different high frequecies. Smaller dogs are more sensitive to higher frequencies.
These dog whistle MP3 files can be used to train yor pet. Download them and make dog whistle ringtones for your cell phone. Or use them as the startup sound or mail notification sound in your computer to fool your pet. (Think prank!)
Thanks to Rick Sowers for the inspiration to do this musical scale and Heidemarie Traylor for suggesting longer samples.
