How do human hearing thresholds compare to those of other animals?


The healthy human ear (children/young adults) can hear sounds from 50Hz anywhere up to 20KHz although there is little that is useful above 8KHz and the human voice rarely exceeds 4.5kHz.

The hearing ability of a dog is dependent on its breed and age. However, the range of hearing is approximately 40 Hz to 60,000 Hz, which is much greater than that of humans. As with humans, some dog breeds become deaf with age, such as the German Shepherd and Miniature Poodle.

Bats require very sensitive hearing to compensate for their lack of visual stimuli, particularly in a hunting situation, and for navigation. Their hearing range is between 20 Hz and 120,000 Hz. They locate their prey by means of echolocation. A bat will produce a very loud, short sound and assess the echo when it bounces back.

Mice have large ears in comparison to their bodies. Mice hear higher frequencies than humans; their frequency range is 1 kHz to 70 kHz or 90 kHz. They do not hear the lower frequencies that we can; they communicate using high frequency noises some of which are inaudible by humans. The distress call of a young mouse can be produced at 40 kHz.

So, how well do humans hear compared to the animals above… not very is the answer.
