Question

You have been hired to invent a whistle to call a trained pet dog back to its owner. This whistle must be heard by the dog, but not by humans. Predict the range of frequencies you could use for your whistle. What is the name of sound given for such frequencies?​

Answer 1

The upper limit of the human hearing range is about 20 kilohertz (kHz) for children, declining to 15–17 kHz for middle-age adults.[2] The top end of a dog's hearing range is about 45 kHz, while a cat's is 64 kHz.[3][4] It is thought that the wild ancestors of cats and dogs evolved this higher hearing range in order to hear high-frequency sounds made by their preferred prey, small rodents.[3] The frequency of most dog whistles is within the range of 23 to 54 kHz,[5] so they are above the range of human hearing, although some are adjustable down into the audible range.
