tunnel through which air vibrations travel from the environment to the tympanic membrane
snail-shaped, liquid-filled structure that contains the structures of the inner ear
Tympanic membrane (eardrum)

pattern of pressure changes in a medium
number of cycles per second that the pressure changes repeat
size of pressure change
unit for designating the frequency of a tone
first harmonic of a complex tone
component of a complex tone that has frequencies that are multiples of the fundamental frequency
quality of sound, ranging from soft to loud
Indicates the sound pressure level (SPL) at threshold for frequencies across the audible spectrum
auditory response area
space that defines the frequencies and sound pressure levels over which hearing functions
quality of sound, ranging from low to high
increase in pitch that occurs as frequency is increased
perceptual similarity of notes separated by one or more octaves
quality that distinguishes between two tones that sound different even though they are the same
first ossicle in the middle ear
second ossicle in the middle ear
group of neurons in the cochlea that contain cilia
last ossicle in the middle ear
sheath that stretches the length of the cochlea and controls the cochlear partition's vibrations
fine hair that protrudes from inner or outer hair cell of the auditory system
structure causing ion channels to open or close
vibration in which the peak travels from the base of the membrane to its apex
prevalence at which a neuron in the auditory system has its lowest threshold
expansion and contraction of the outer hair cells in response to sound
medial geniculate nucleus
auditory thalamus component which transfers input from inferior colliculus to auditory cortex
auditory receiving area (A1)
primary receiving space for hearing located in the temporal lobe
form of sensorineural hearing loss that occurs as a function of age
noise-induced hearing loss
form of sensorineural deafness that occurs when loud sounds cause degeneration of the hair cells
hidden hearing loss
deafness that occurs at high sound levels, even though the person's thresholds are normal
plot of hearing loss versus frequency
device in which electrodes are inserted into the cochlea to create hearing
As the pair of tones increase in loudness, our perception of the difference between them:
a. Gets more pronounced (they appear more different).
What does perception of changes in loudness across these pairs suggest about our ability to perceive loudness?
a. We are more sensitive to changes in loudness at high intensities (dBs).
What does the audibility curve suggest about our hearing?
a. That we are differentially sensitive to tones of varying frequencies.
What does the audibility curve suggest about our perception of tones 1 and 7?
a. A higher intensity is needed to perceive tone 1 than is needed to perceive tone 7.
Tone height refers to the fact that:
a. Pitch perception increases as frequency of the tone increases.
Two (different) tones that share the same chroma:
a. Are separated by one (or more) octave(s), and therefore sound very similar.
Removing harmonics from the tone has what effect on your perception of the sound?
a. Pitch stays the same, but timbre changes.
Two (different) tones that have the same loudness, pitch, and duration, yet sound different:
a. Have a different timbre.
What is the nature of the relationship between harmonics and timbre?
a. Adding harmonics to a tone gives it a richer timbre.
Why does it sound so bizarre to hear this melody when each tone is played backwards?
a. Because we are used to hearing a buildup of sound with each new tone, followed by a decrease in sound.
Look at the sound "envelopes" for each tone in the diagram. For the "forward" version, what is the period of large intensity at the beginning of each tone?
a. The attack of the tone.
Ian is in a band, and has taken the time to learn the ins and outs of the sound system. For example, he knows that when the diaphragm of a loudspeaker moves back in, a process called _____ occurs.
Ed is measuring the frequency of sounds in units. What are these units called?
Ellie is conducting auditory research on pure tones. She is measuring the repetition rate of the tones. What is another term for what Ellie is measuring?
b. fundamental frequency
Maelynn is an audiologist. She knows that we are most sensitive to sounds at frequencies between 2,000 and _____ Hz, which is also the range for understanding speech.
The aspect of auditory sensation whose variation is associated with musical melodies is _____.
Riley and Aaron are in an orchestra. Riley plays the flute and Aaron plays the oboe. To warm up, they play the same note at the same loudness, pitch, and duration. Yet the audience can still distinguish between the two, due to the difference in _____.
Erica is studying the structure of the middle ear and its role in sound perception, specifically the three smallest bones in the body known as the _____.
Pat is studying how a sound's frequency determines the timing of electrical signals. He finds that auditory nerve fibers fire in synchrony with the rising and falling pressure of the pure tone. Pat is studying _____.
b. phase locking
Matthew is conducting a study on the basilar membrane. He finds that the base is tuned to high frequencies and the apex is tuned to low frequencies, and that the best frequency varies continuously along the basilar membrane between these extremes. Matthew's research supports which theory?
b. place theory
Doug likes to listen to his music at top volume through his earphones. He is likely to incur hair cell damage over time, otherwise known as _____.
