Audiology Final Exam (CDO 331 CMU)
ACTUAL QUESTIONS AND CORRECT
ANSWERS
Conductive Hearing Loss - CORRECT ANSWERS Audiogram- gap between bone
(normal) and air conduction



Tympanometry- Type B Typically



Acousitc Reflex- Ipsy in ear is absent; contra both absent



OAES- usually no OAEs



ABR- typically good ABR's just make sound loud enough



Sensorineural Hearing Loss (Cochlear) - CORRECT ANSWERS Audiogram- bone and air
conduction are close together (10dB or less), neither are normal



Tympanometry- normal



Acousitc Reflex- Ips with HL is absent, contra presented with sound w/HL is absent



OAES- Abnormal/Absent



ABR- Typical

, Sensorineural Hearing Loss (Retrocochlear) - CORRECT ANSWERS Audiogram-
variable; either normal results or sensorineural loss



Tympanometry- normal



Acoustic Reflex- variable; abnormal if in the path tested, normal if not in test path



OAES- normal



ABR- variable; abnormal if in the path tested, normal if not in test path



Anotia - CORRECT ANSWERS The complete absence of a pinna



Microtia - CORRECT ANSWERS A small sized, or not completely developed pinna



Atresia - CORRECT ANSWERS When part or all of the ear canal does not form.

This would cause a conductive hearing loss



Stenosis - CORRECT ANSWERS The narrowing of the ear canal, which causes
conductive hearing loss



External Otitis - CORRECT ANSWERS Bacterial infection (sometimes it may be a fungal
infection) of the ear canal.

Also known as Swimmer's Ear.

This could cause conductive hearing loss.
