CHAPTER 19 ACOUSTICS AND THE EAR
... Several factors contribute to impedance matching in the middle ear. First, the area of the tympanic membrane is much larger than that of the membrane-covered opening to the inner ear (the oval window). This difference in size means that pressure that was originally distributed over a large area at t ...

... Frequency is the number of waves per unit time. For example a very low frequency means that the wave length is very long creating a lower pitch and a high frequency would have a very thin wave length, this creates a high pitched sound. If you look at a sign wave diagram Frequency applies to the X ex ...

... frequency, just like higher amplitude, means more energy. Wave speed is the speed at which a wave travels. The speed of a wave depends on the medium in which the wave is traveling. Sound waves travel fastest in solids, next fastest in liquids, and slowest in gases. Wave speed can be calculated by mu ...

... The relationship between the ear and sound waves to explain hearing is as follows: Sound waves are gathered by the outer ear which is shaped to help capture the sound waves (energy transferred in particles of air) and send them through the ear canal, which transfers them to the eardrum. The vibr ...
