 Hearing Man hears sounds when any vibrating object pushes air molecules at a rate between 15 and 15,000 vibrations per second. Sound waves are turned into nerve impulses inside the cochlea. |
Smell Odors come from molecules of gas that have been released into the air from many different substances. These molecules stimulate receptor cells deep inside the nose. |
