How sensitive is the dog’s sense of hearing

A dog’s hearing is 16 times that of a human, and usually a human cannot easily hear bass sounds from 6 meters away, while a dog can hear bass sounds from 24 meters away. The hearing range of dogs is also wide, the human hearing range is generally 20,000 Hz, while the dog is 40,000 Hz or even higher, thus dogs can hear the calls of voles, bats, etc.. The dog flute, which is inaudible to human ears, is made according to this characteristic of dogs. At night, dogs remain highly alert even when sleeping and can distinguish various sounds within a radius of 1,000 meters. The canine ear can also determine the direction of the sound source, and the canine ear can turn with the direction of the sound. This feature enables police dogs and hunting dogs to accurately pick up the sound they hear to indicate the target for their owners, and to track and besiege prey at the master’s behest.
