Did you know?
In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane). The compression and rarefaction of these waves set this thin membrane in motion, causing sympathetic vibration through the middle ear bones (the ossicles: malleus, incus, and stapes), the basilar fluid in the cochlea, and the hairs within it, called stereocilia. These hairs line the cochlea from base to apex, and the part stimulated and the intensity of stimulation give… Web18 rows · Sound is measured in decibels (dB).

Web8 Jul 2016 · So, for example, from the human audiogram you can see that people hear pretty well at 1,000Hz; here, the threshold of hearing is a scant 2 decibels. For rats, however, the threshold is more like 24dB. That means that a 20dB sound at 1,000Hz would be easily audible to you but would be entirely inaudible to the rodent.
