Which type of hearing loss results from damage to the outer or middle ear, preventing adequate sound transmission to the cochlea?
Answer: Conductive hearing loss
Conductive hearing loss occurs when a mechanical problem in the outer or middle ear reduces the transmission of sound energy to the inner ear.
On an audiogram, the air-bone gap indicates which finding?
Answer: Conductive component to the hearing loss
An air-bone gap, where bone conduction thresholds are better than air conduction thresholds, indicates a conductive component to the hearing loss.
Otoacoustic emissions (OAEs) measure the function of which structure?
Answer: Outer hair cells of the cochlea
OAEs are sounds generated by the outer hair cells of the cochlea and are measured to assess cochlear (outer hair cell) integrity.
Which audiological test assesses the integrity of the auditory brainstem pathway by measuring electrical responses to sound?
Answer: Auditory brainstem response (ABR)
The ABR records electrical responses from the auditory nerve and brainstem to click or tone-burst stimuli, assessing neural pathway integrity.
Presbycusis is defined as age-related hearing loss and typically presents as which audiometric pattern?
Answer: High-frequency sensorineural hearing loss
Presbycusis typically causes a bilateral, symmetric, high-frequency sensorineural hearing loss due to cochlear hair cell degeneration with age.
Tympanometry assesses the function and compliance of which structure?
Answer: Tympanic membrane and middle ear system
Tympanometry measures tympanic membrane compliance and middle ear pressure to assess middle ear function and pathology.
