Document Summary
*eve-marie clapped hands* moved and changed the air pressure where she has clapped hands; you are changing the air pressure at a speciic locaion. These changes in air pressure are what we will receive at our ear. In outer ear the larger porion is the pinna which captures these changes in air pressure, move down the ear canal up to the tympanic membrane (ear drum) which will take in the changes in air pressure. Causes a cascade of movements in the ossicles which transmit the vibraion of the ear drum to the inner ear where the cochlea (most perinent part in audiion) will transmit this change in air pressure to a neural signal. The cochlea = snail shaped structure, unfolded you can see the basilar membrane in the middle (really important part for auditory percepion) There are hair cells associated with this membrane. Range from 20-20000 hz, range of the human ear normal hearing.
