Audiology and Hearing Sciences Flashcards

A Type B tympanogram with no peak indicates which middle ear condition?

Answer: Middle ear fluid (otitis media with effusion)

A Type B (flat) tympanogram indicates reduced tympanic membrane mobility, most commonly due to middle ear effusion.

The acoustic stapedial reflex is elicited by loud sounds and involves contraction of which muscle?

Answer: Stapedius muscle

The acoustic reflex involves reflexive contraction of the stapedius muscle in response to loud sounds, stiffening the ossicular chain.

Universal newborn hearing screening (UNHS) in the US uses which two primary technologies?

Answer: OAE and ABR

UNHS programs use OAE and/or ABR testing because both are objective, require no behavioral response, and can be performed on sleeping newborns.

Central auditory processing disorder (CAPD) is characterized by difficulty processing auditory information despite:

Answer: Normal peripheral hearing sensitivity

CAPD involves deficits in processing, interpreting, or using auditory information even when peripheral hearing thresholds are within normal limits.

Which term describes the perception of sound (ringing, buzzing, hissing) in the absence of an external sound source?

Answer: Tinnitus

Tinnitus is the subjective perception of sound without an external acoustic stimulus, often associated with cochlear damage.

Cochlear implants provide auditory stimulation by delivering electrical signals directly to which structure?

Answer: Spiral ganglion neurons of the auditory nerve

Cochlear implants bypass damaged hair cells and electrically stimulate the spiral ganglion neurons (auditory nerve fibers) to restore sound perception.
