Exam 10: Sound and the Ears

The cochlea is located in the:

Type I auditory nerve fibers:

Which term can BEST be defined as a frequency representation based on a match between the frequencies of incoming sound waves and the firing rates of auditory nerve fibers?

Auditory transduction occurs when inner hair cells release:

Presbycusis is NOT caused by:

The _____ is a small bone in the inner ear that transmits sound energy from the tympanic membrane to the incus.

A _____ is NOT an external component of a cochlear implant.

In the context of hair-cell death, which statement is TRUE of excitotoxicity?

How does the basilar membrane determine the place code for frequency representation?

_____ is one of the MOST important physical dimensions of sound.

Why do people often chew gum to maintain their hearing and minimize physical discomfort during an airplane takeoff?

In the context of auditory perception, inner hair cells are connected to:

The amplitude for pain threshold is _____ dB SPL.

Giselle sings in a B-flat note, while her brother plays his trumpet in the same note. The pitch and loudness in both of these cases are the same. The difference in sound quality between these two sounds is called:

If a 15,000-Hz tone enters the inner ear, the peak of the traveling wave in the basilar membrane will be:

A high-fidelity loudspeaker creates sound when a diaphragm in the shape of a flattened cone vibrates back and forth. The forward movement creates waves of compression, and the backward movement creates rarefaction. These movements create a complete sound pressure cycle. If the tone goes through 1,000 cycles per second, what is the frequency of the sound being produced?
