Lesson 8 - Pure Tone Testing Flashcards
In Pure Tone testing, threshold means:
a. the lowest intensity the client here’s 50% of the time
b. the sound has a loudness zero dB in a 2 cc coupler
c. point at which the client reports the sound is most comfortable
d. 0 dB HL
a. the lowest intensity the client here’s 50% of the time
What is the meaning of 40 dB threshold re: audiometric zero, at 500 Hz?
a. subject could not here at 500 Hz tone at 40 dB
b. subject could barely hear a 500 Hz tone at 40 dB about 50% of the time
c. subject could hear a 500 Hz tone very well at 40 dB, and 5 dB lower
d. subject could hear a 500 Hz tone with the hearing dial set at zero
b. subject could barely hear a 500 Hz tone at 40 dB about 50% of the time
The problem is produced by excessive ambient noise are:
a. greater for the lower frequencies than the higher frequencies
b. greater for the higher frequencies than the lower frequencies
c. affecting both high and low frequencies equally
d. not a problem because a headset covers the ears
a. greater for the lower frequencies than the higher frequencies
Before testing is done:
a. the clients ears should be carefully examined using an otoscope
b. you should carefully remove any impacted cerumen, if the client so requests
c. you should hand the earphones to the client so that he can put them on in a comfortable manner
d. none of the above
a. the clients ears should be carefully examined using an otoscope
The descending technique in pure tone audiometry is preferred because it:
a. is easier to hear when a sound stops than when it begins
b. is the easier for the operator to explain to the client
c. can prevent ‘hearing fatigue’
d. all of the above
a. is easier to hear when a sound stops than when it begins
Begin testing with the 1000 Hz tone because it:
a. is the center frequency of those most important to understanding speech
b. has good test re-test reliability
c. provides the opportunity for the client to become accustomed to the procedure
d. all of the above
b. has good test re-test reliability
The symbols used in the audiogram for air conduction are:
a. uniform for the United States only
b. uniform for Europe only
c. uniform world wide
d. a circle for the left, and x for the right
c. uniform worldwide
Individual with a noise induced hearing impairment can have a ‘V’ notch at which frequency?
a. 3000 Hz
b. 4000 Hz
c. 6000 Hz
d. any of the above
d. any of the above
The loss of acoustic energy as it travels from the test ear to the non-test year is the definition of:
a. tonal deficiency affect
b. interaural attenuation
c. occlusion effect
d. auditory fatigue
b. interaural attenuation
To begin testing for air or bone conduction thresholds, tests should begin at which frequency?
a. 1000 Hz
b. 2000 Hz
c. 500 Hz
d. 250 Hz
a. 1000 Hz
