Psych 230 UIUC Units 5-9 Latest Exam
with All Complete Solutions 2025-2026
Set.
sound stimulus - Answer the periodic variations in air pressure traveling out from a source
sound waves - Answer waves of pressure changes in air caused by the vibrations of a source
medium of sound - Answer A material (solid, liquid, or gas, or combination of these) through
which a wave travels.
compression - Answer high pressure
rarefaction - Answer low pressure
cycles - Answer the amount of time between one peak of high pressure and the next
pure tones - Answer sound waves in which air pressure changes follow the basic sine wave
format
amplitude - Answer difference between the maximum sound and minimum sound pressures
loudness - Answer the perceptual experience of the amplitude or intensity of a sound
stimulus
decibel (dB) - Answer measures loudness
Frequency - Answer the number of cycles in a sound stimulus that occur in 1 second
pitch - Answer the subjective experience of frequency
Hertz (Hz) - Answer Unit of measurement for frequency
, Pinna - Answer outer ear; collects sound and funnels it into the auditory canal
external auditory canal - Answer Conducts sound to the tympanic membrane;
Amplifies specific sound frequencies
tympanic membrane - Answer eardrum; thin elastic sheet
Eustachian tube - Answer connects the middle ear to the pharynx; It equalizes air pressure
on both sides of the eardrum
tensor tympani and stapedius - Answer muscles attached to the malleus and stapes; tense in
the presence of loud noises; reduce vibrations
ossicles - Answer the bones in the middle ear that conduct sound mechanically; goal is to
amplify sounds
malleus, incus, stapes - Answer What are the three ossicles?
stapes - Answer Pushes against the oval window of the cochlea resulting in sound moving to
the inner ear
inner ear - Answer transduces sound into a neural signal
cochlea - Answer snail-shaped structure of the inner ear that houses the hair cells
3 liquid-filled chambers of cochlea - Answer tympanic canal
middle canal
vestibular canal
3 membranes of the cochlea - Answer Tectorial
Basilar
