This is why dogs can hear sounds that are pitched too high for the human ear, such as a dog whistle, and why they sometimes start howling at sirens minutes before we can hear them. Today, a dogs hearing capabilities can be tested without the dog having to do a thing. This sensitivity to higher-pitched sounds likely explains several phenomena involving dogs.

"One area being actively looked at is whether you get hearing damage from not just intensity of sound but sound dose. "But the bad news is that the physiology mechanisms that give us this amazing ability are very fragile, so loud noise exposure, or certain types of brief loud sounds, like explosions, can irreversibly damage those inner hair cells of the ear. Neuronal representations of distance in human auditory cortex. A sounds frequency is measured by the number of vibrations it creates per second.
