CCC Audiology and Hearing Sciences 2 — Questions and Answers
Question 1: A Type B tympanogram with no peak indicates which middle ear condition?
- Normal middle ear function
- Eustachian tube dysfunction with negative pressure
- Middle ear fluid (otitis media with effusion) (Correct answer)
- Ossicular discontinuity
Correct 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.
Question 2: The acoustic stapedial reflex is elicited by loud sounds and involves contraction of which muscle?
- Tensor tympani
- Stapedius muscle (Correct answer)
- Tensor veli palatini
- Levator veli palatini
Correct answer: Stapedius muscle
The acoustic reflex involves reflexive contraction of the stapedius muscle in response to loud sounds, stiffening the ossicular chain.
Question 3: Universal newborn hearing screening (UNHS) in the US uses which two primary technologies?
- Pure tone audiometry and ABR
- OAE and ABR (Correct answer)
- Tympanometry and OAE
- Behavioral audiometry and OAE
Correct 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.
Question 4: Central auditory processing disorder (CAPD) is characterized by difficulty processing auditory information despite:
- Normal cognitive ability
- Normal peripheral hearing sensitivity (Correct answer)
- Normal language skills
- Normal reading ability
Correct answer: Normal peripheral hearing sensitivity
CAPD involves deficits in processing, interpreting, or using auditory information even when peripheral hearing thresholds are within normal limits.
Question 5: Which term describes the perception of sound (ringing, buzzing, hissing) in the absence of an external sound source?
- Hyperacusis
- Diplacusis
- Tinnitus (Correct answer)
- Auditory hallucinations
Correct answer: Tinnitus
Tinnitus is the subjective perception of sound without an external acoustic stimulus, often associated with cochlear damage.
Question 6: Cochlear implants provide auditory stimulation by delivering electrical signals directly to which structure?
- Outer hair cells
- Spiral ganglion neurons of the auditory nerve (Correct answer)
- Auditory brainstem
- Tympanic membrane
Correct 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.
