Overview:

How does it work?Dogs hear higher pitch sounds than people. That''s why dog whistles seem to be silent. Dogs hear the high frequency sounds that we can''t. High frequency sounds usually travel further than voices and can be heard further away. These high frequency sounds have the effect of immediately getting a dog''s attention. Dog whistles are typically used as part of a training routine designed to train your dog to do tricks or for behavior modification. A pure tone is much easier for a dog to distinguish compared to verbal commands. Different sound patterns can be used to trigger different responses. For example, two short bursts could mean "stop" and one long burst could mean "lie down".For general info on dog whistles, the following is a useful Wikipedia link: http://en.wikipedia.org/wiki/Dog_whistleFeatures-3 Whistle-Variable frequency tone generator-2 different waveform - sine and square wave.
