Audiology and Speech Disorders — Flashcards

Flashcard 51: Wave IV of BERA is produced by the _____

Answer: Superior olivary complex

Flashcard 52: _____ is an objective test used widely to assess middle ear function, particularly in children

Answer: Impedance audiometry

Flashcard 53: In Electrocochleography, the _____ potential measures the electrical activity in distal part of auditory nerve

Answer: Action

Flashcard 54: Stapedial reflex is activated at a sound level of _____dB over the threshold of patient's hearing

Answer: 70-100

Flashcard 55: The symbol "]" in Pure Tone Audiometry (PTA) indicates:

Answer: Masked Bone Conduction (Left)

Extra: Standard PTA Symbols: - Right Ear (Red): AC = O, BC (unmasked) = <, BC (masked) = [ - Left Ear (Blue): AC = X, BC (unmasked) = >, BC (masked) = ]

Flashcard 56: _____ test is done to rule out malingering in hearing

Answer: Stengers

Flashcard 57: _____ is an objective test that records electrical activity occurring in the auditory pathway.

Answer: BERA

Flashcard 58: Which instrument is used to measure middle ear compliance and pressure?

Answer: Tympanometer

Extra: Tympanometry is an objective test of middle-ear function (acoustic immitance). It measures the mobility of the tympanic membrane and the conduction bones by creating variations of air pressure in the ear canal. Common results include Type A (normal), Type B (flat - fluid/perforation), and Type C (negative pressure - ET dysfunction).

Flashcard 59: Recruitment is tested by _____ test

Answer: ABLB (Alternate Binaural Loudness Balance)

Flashcard 60: In a Downsloping/descending audiogram- _____ frequencies affected first

Answer: higher
