<P> To human ears , a dog whistle makes only a quiet hissing sound . The advantage of the dog whistle is that it does n'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 . </P>
