1
Q

what form of energy is used in the cochlea?

A

hydrodynamic energy and electrochemical energy as it goes up the auditory nerve

2
Q

• disorder characterized by a sudden unilateral hearing loss, tinnitus, vertigo

A

Meniere’s disease

3
Q

The use of summing or averaging computers to observe the very small electrical responses to sound front eh cochlea, brain stem, and cortex

A

auditory evoked potentials

4
Q

difference between speech recognition and word recognition

A

speech recognition measured in decibels and word recognition measured in percentage

5
Q

speech recognition threshold uses

A

spondi words

6
Q

word recognition uses only _____

A

one syllable word

7
Q

a rapid test to detect auditory processing disorders?

A

Screening test for auditory processing disorders

8
Q

What is an acoustic neuroma?

A

a benign tumor involving the nerve sheath of the auditory nerve

9
Q

Ototoxic medication most frequently affect low or high frequencies?

A

high frequencies because they are closer to opening of cochlea

10
Q

What is the purpose of bone conduction audiometry?

A

Tests function of inner ear it tests the cochlea

11
Q

The are at the base of the brain at the junction of the cerebellum, medulla and pons?

A

cerebellopontine angle

12
Q

Two syllable term with equal stress on both words

A

spondee

13
Q

What is an air bone gap?

A

Difference between air conduction and bone conduction

Find that bone conduction is better than air conduction

14
Q

What is presbycusis?

A

Loss of hearing due to aging process

15
Q

Why is it impossible for bone conduction to be worse than air conduction?

A

Air conduction is testing the whole system

Bone conduction shouldn’t be any worse than the entire system

16
Q

What is the term binaural mean?

A

listening with both ears to either the same or different stimuli

17
Q

what is done to determine that the equipment is functioning according to specifications?

A

calibration

18
Q

a patient who signals that a tone was hard when no tone was presented is given what type of response?

A

False positive

19
Q

Why should diagnostic testing be conducted in a sound booth

A

To keep the background noise from making it look like a hearing loss

20
Q

What type of hearing loss is considered a medical emergency?

A

sudden hearing loss

21
Q

The graph on which a hearing test is plotted

A

audiogram

22
Q

Name three symptoms of an acoustic neuroma

A

vertigo
tenitus
unilateral hearingloss sensorineural

23
Q

The lowest level at which a person knows a person is talking

A

speech detection threshold/speech awareness threshold

24
Q

What is vestibule?

A

Cavity of inner ear containing the organs of equilibrium and giving access to the cochlea

25
Q

Cross hearing occurs by air conduction or bone conduction?

A

Both

26
Q

The loss of energy of a sound introduced by one ear and heard by the other

A

Interaural attenuation

27
Q

What is auditory neuropathy spectrum disorder?

A

normal outer hair cell function in cochlea, but the responses on the VIIIth nerve that carries electrical signals to the brain fail to occur in synchrony.

28
Q

What types of words are used for measuring the speech recognition threshold?

A

One syllable word Phonetically balance

29
Q

What does the term monaural mean?

A

one ear

A

4000 Hz

33
Q

What is the difference between an SAT and an SRT?

A

SRT is speech recognition

sat is speech awareness

34
