what does a silent dog whistle sound like?
a quiet hissing sound
to human ears, a dog whistle makes only a quiet hissing sound. the advantage of the dog whistle is that it doesn't produce a loud irritating noise for humans that a normal whistle would produce, so it can be used to train or command animals without disturbing nearby people. some dog whistles have adjustable sliders for active control of the frequency produced. trainers may use the whistle simply to gather a dog's attention, or to inflict pain for the purpose of behaviour modification.

a dog whistle (also known as silent whistle or galton's whistle) is a type of whistle that emits sound in the ultrasonic range, which people cannot hear but some other animals can, including dogs and domestic cats, and is used in their training. it was invented in 1876 by francis galton and is mentioned in his book "inquiries into human faculty and its development", in which he describes experiments to test the range of frequencies that could be heard by various animals, such as a house cat.
