Safe Use of Portable Music Players and Headphones
... Headphones that fit over or on the ear are a better choice than ear buds. Over-ear headphones put the source of the sound farther away from your inner ears. This extra space can protect your eardrums from the strain and subsequent damage caused from listening to noise directed straight into the ear ...

and the outer hair cells
... It is inside the organ of corti that we find the hair cells. These are nothing to do with hairs on your head. They are the receptors involved in changing the sound pressure wave into a nerve signal. Hair cells get their name from the hair like projections at their top which are known as 'cilia'. The ...

Tympanoplasty Mastoidectomy
... Tympanoplasty is a procedure where the ear drum is rebuilt using a graft. This can be done to close a hole in the ear drum, or as part of a more extensive procedure including mastoid surgery. Mastoidectomy is a procedure done to evaluate and clean out the bone behind the ear. The mastoid is a honeyc ...

The Human Ear - AP Psychology
... Changes in pitch are caused by differences in the frequency at which a sound wave vibrates. • On a graph, the more waves per second results in a higher tone, and the less waves per second results in a lower tone. • Pitch is measured in Hertz (Hz) – how many times a wave repeats per second • Min = 20 ...
