The alternating increases and decreases in sound pressure are called these.
What are condensation and rarefaction?
The middle ear overcomes this mismatch between air and cochlear fluid.
What is the impedance mismatch?
The gelatinous structure that makes contact with the hair cell stereocilia
What is the tectorial membrane?
Audiologists help prevent, diagnose, and treat this common communication disorder.
What is hearing loss?
X axis on the audiogram
What is frequency?
The smallest pressure detectable by the auditory system.
What is 20 micropascals?
The structure responsible for equalizing pressure and maximizing TM mobility.
What is the Eustachian tube?
This type of hearing loss results from damage to the cochlea.
What is sensorineural hearing loss?
Cranial nerve that innervates the vestibular system
What is the 8th cranial nerve?
The perceptual correlate of frequency.
What is pitch?
The three bones of the middle ear are collectively known as this.
What are the ossicles?

What is macula?
What is the sensorineural?
The reflex that protects the inner ear from loud sounds.
What is the acoustic reflex?
How the inner ear or cochlea is organized (i.e. the basal end of the cochlea corresponds to high frequencies)
What is tonotopically?
The sensory structure in the semicircular canals
What is the crista ampullaris?
65 dB HL (degree)
What is moderately severe?
This auditory effect occurs when sound waves interact and cancel each other due to differences in phase.
