Week 6 Flashcards
Before electroacoustical & electrophysiological tests, what were popular way for audiologists to seperate sensory from neural hearing losses?
Behavioral measures
What are behavioral measures?
such tests as those to determine how long a patient could perceive a sustained tone
-the test that balanced the perception of a tone’s loudness between the ears
3 measures made on acoustic immitance meters
- Static acoustic compliance
- Typanometry
- Acoustic Reflex
Static acoustic compliance or admittance
the mobility of the eardrum in response to a given value of air pressure in the EAC
A measurement of middle-ear pressure, determined by the mobility of the tympanic membrane as a function of various amounts of positive and negative air pressure in the EAC
Tympanometry
Acoustic reflex is
the contraction of the middle-ear muscles
What is C1?
the first measurement, made with the tympanic membrane loaded with +200 daPa of pressure
