Chapter 10 Vocabulary

Front 1

conductive hearing loss

Back 1

results when something interferes with transmission

Front 2

sensorineural mechanism

Back 2

the inner ear and auditory nerve together

(sensori = hair cells)

Front 3

Immittance

Back 3

a measure of how easily a system can be set into vibration by a driving force

Front 4

impedance

Back 4

describes how a system opposes the flow of energy through it, and measured in ohms

Front 5

admittance

Back 5

refers to how easily energy is transmitted through a system and is measured in millimeters

Front 6

acoustic admittance meter

Back 6

immitance is measured and displayed

Front 7

tympanometer

Back 7

(acoustic admittance meter) capable of three clinical tests: tympanometry, static acoustic middle ear admittance, and acoustic reflexes

Front 8

tympanometry

Back 8

generates a graph called a tympanogram

Front 9

tympanogram

Back 9

plot of changes in middle ear admittance as air pressure is systematically varied in the external ear canal

Front 10

static acoustic middle ear admittance

Back 10

the admittance of the middle ear at a specified ear canal pressure value

Front 11

acoustic reflex testing

Back 11

acoustic reflex threshold testing and acoustic reflex decay testing

Front 12

acoustic reflex threshold

Back 12

bilateral

an acoustic signal of sufficient intensity presented to either ear will cause the stapedius muscles to contract in both ears

Front 13

acoustic reflex decay test

Back 13

the acoustic stimulus is presented for 10 seconds at a level 10 dB above the threshold level and the change in reflex magnitude is monitored.

Front 14

auditory brain stem response test

Back 14

a measure of neuroelectric potentials that occur within about 10msec after auditory stimulation

Front 15

specific language impairment

Back 15

a disorder in which children show a significant problem with language despite having normal hearing, normal nonverbal intelligence, and no known neurological problems

Front 16

temporal processing problem

Back 16

difficulty processing rapid acoustic signals
