Exam 9: Sound and the Ears

Georg von Békésy demonstrated how a place code for frequency resulted from movement of the basilar membrane due to differences in along its length.

Shearing force occurs on the stereocilia of because of movements of the basilar and tectorial membranes.

The auditory canal is part of the

Discuss the roles of outer hair cells and inner hair cells in the process of sound transduction.

The ossicles are found in the

Many high-fidelity musical components have a button labeled "loudness." Pushing this button amplifies low-frequency sounds.From a psychophysical standpoint,why should loudness only be pushed when listening to music at low amplitudes?

A pure tone results from air pressure changes over time that fit a mathematical formula called

The audibility curve shows that auditory sensitivity is maximal for

The organ of Corti

The three physical dimensions of sound are

For frequencies between 4,000 and 8,000 Hz,audiograms indicate that

The basilar membrane is at its base than at its apex.

The audibility curve shows that auditory threshold is minimal for

______________ is the physical unit of measurement that is logarithmically related to sound pressure mea- sured in micropascals.

Fourier analysis is a mathematical procedure for decomposing a waveform into a collec- tion of .

The organ of Corti has three critical components called the inner hair cells,

The text describes the as a "relief valve" at the base of the tympanic canal.

Shearing force occurs on the stereocilia of the inner hair cells because of movement of the
