SILENT DOG WHISTLES
Ultrasonic training whistle.
Please note;
All "silent" training whistles are very high frequency, but the most are not completely silent to the human ear.
At the very least, when you blow on the whistle, you can hear the sound made by the air being forced through the metal tubing.
