Assessment of Hearing

Question 1

audiometer

Answer 1

machine that generates and amplifies pure tones for air conduction hearing testing

Question 2

Pure tone Audiometry

Answer 2

pure tone hearing test used to determine hearing thresholds at different frequencies (conductive hearing)

Question 3

Bone conduction testing

Answer 3

tests sensitivity to the sensorineural portion of hearing a bone vibrator is placed on the forehead or behind the test ear, sound strikes the bones of the skull, bones vibrate thus stimulate the fluid in both inner ears

Question 4

Masking

Answer 4

• noise is sent through a headphone at a level that is strong enough to mask the tone heard in the opposite ear in bone conduction
• noise is presented to the non-test ear when it is markedly better than test ear to prevent inaccurate test data

Question 5

Speech Audiometry

Answer 5

measures how well a person can understand 50% of the words presented at the lowest/softest level of hearing when presented with spondee words

Question 6

spondee words

Answer 6

used during speech audiometry, these words are two-syllable words with equal stress on each syllable ex. baseball, hotdog, cowboy, birthday

Question 7

word discrimination/recognition test

Answer 7

establishes how well a patient discriminates between words by having them correctly repeat monosyllabic words like cap, day etc

Question 8

Acoustic Immitance

Answer 8

refers to the transfer of acoustic energy that takes. place when a sound stimulus reaches the external ear canal and strikes the TM

Question 9

impedance

Answer 9

resistance to the flow of sound energy
