Özet:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A dog whistle (also known as silent whistle or Galton's whistle) is a type of whistle used in the training of dogs and cats. It was invented by Francis Galton; the whistle was mentioned in his book Inquiries into Human Faculty and its Development. In his discussion (Galton 1883:26-27) of his experiments to test the range of frequencies that could be heard by various animals, he notes that cats have the most all-round sensitive hearing, being able from a considerable distance to hear notes too high in frequency for humans to hear, and small dogs can also hear these notes, while large dogs cannot.
