ultrasonic dog whistle

Posted on Feb 6, 2014

It`s well known that many animals are particularly sensitive to high-frequency sounds that humans can`t hear. Many commercial pest repellers based on this principle are available, most of them operating in the range of 30 to 50 kHz. My aim was, however, to design a slightly different and somewhat more powerful audio frequency/ultrasonic sound generator that could be used to train dogs. Just imagine the possibilities - you could make your pet think twice before barking again in the middle of the night or even subdue hostile dogs (and I guess burglars would love that!)..
