Audiology Flashcards
Conductive Hearing Loss
Sounds cannot get through outer and middle ear
Sensorineural Hearing Loss
Inner ear damage/problems with nerve pathways
Normal Hearing
-10 - 15 dB
Slight Hearing Loss
16 - 25 dB
Mild Hearing Loss
26 - 40 dB
Moderate Hearing Loss
41 - 55 dB
Moderate - Severe Hearing Loss
56 - 70 dB
Severe Hearing Loss
71 - 90 dB
Profound Hearing Loss
91+ dB
Flat Configuration
AC Thresholds within 20 dB of each other
Rising Configuration
AC thresholds for low frequencies at least 20 dB poorer than for high frequencies
Sloping Configuration
AC thresholds for high frequencies at least 20 dB poorer than for low frequencies
Precipitous Configuration
High frequency thresholds worsen by at least 20 dB per octave
Tympanometry
Measurement of eardrum immittance as a function of air pressure in the ear canal
Tympanometry Procedure
A soft rubber tip is inserted into the ear canal, changing the pressure in the ear canal
