Damage to the primary auditory cortex results in ____.
difficulty in responding to sequences of sounds
Tinnitus may be ____.
due to a phenomenon like the phantom limb

frequency
The ____ of a sound is the number of compressions per second.
frequency
The fact that the refractory period limits the firing rate of a neuron is problematic for which of the following?
frequency theory only
Perception of a low tone is to ____ as perception of a high tone is to ____.
frequency theory; place theory
Vibrations in the fluid of the cochlea causes ____.
hair cells to displace
A sound shadow refers to ____.
how much louder a high-frequency sound is for the ear closest to the sound
Which of the following is true for nerve deafness?
it can result from damage to the cochlea
What is the perception of the intensity of a sound wave called?
loudness
What sound characteristics can be compared between the two ears to locate the source of the sound?
loudness and timing
In the auditory system, hair cells are specialized receptors that respond to ____.
mechanical displacement
Conductive deafness is also known as ____.
middle ear deafness
Why is it important for sound vibrations to be amplified as they pass through the ear?
much force is needed to create waves in fluid
What kind of deafness is the result of damage to the cochlea or the hair cells?
nerve
What kind of deafness is the result of damage to the cochlea or the hair cells?
nerve
Where are the auditory receptor cells located?
on the basilar membrane
The tympanic membrane connects to three tiny bones that transmit the vibrations to the ____.
oval window
Humans localize low frequencies by ____ differences and high frequencies by ____ differences.
phase; loudness
The structure that we commonly refer to as the ear (on the outside of the head) is formally known as the ____.
pinna
What occurs to a tone as the frequency increases?
pitch gets higher
Timing differences can be used most accurately for localizing ____.
sudden-onset sounds
To what lobe of the cerebral cortex is auditory information sent?
temporal
Most auditory information is sent to which hemisphere of the brain?
the contralateral side
Three small bones connect the tympanic membrane to the oval window. What is the function of these bones?
they convert airwaves into waves of greater pressure
The eardrum is also known as the ____.
tympanic membrane
The current view of how we perceive high frequencies is based on ____.
where along the basilar membrane neurons fire most rapidly
According to the frequency theory, the ____.
basilar membrane vibrates in synchrony with a sound, producing action potentials at the same frequency
How do sound waves ultimately result in the production of receptor potentials?
hair cells in the cochlea vibrate, causing ion channels to open in their membrane
