Lesson 8 Flashcards
The Pure Tone testing threshold means
the lowest intensity the client hears 50% of the time
What is the meaning of 40 dB threshold re: audiometric zero, at 500 Hz?
subject could barely hear a 500 Hz tone at 40 dB about 50% of the time
The problems produced by excessive ambient noise are
greater for the lower frequencies than the higher frequencies
Before testing is done
the client’s ears should be carefully examined using an otoscope
The descending technique in pure tone audiometry is preferred because
it is easier to hear a when a sound stops than when it begins
Begin testing at 1000 Hz tone because it
has good test re-test realiability
The symbols used in the audiogram for air conduction are
uniform worldwide
Individuals with noise induced hearing impairment have a “V” notch at which frequency? 3000 ,4000 6000 , any of above
any of the above
The loss of acoustic energy as it travels from the test ear to the non-test ear is a definition of
interaural attenuation
To begin testing for air or bone conduction thresholds, tests should begin at which frequency?
1000 Hz
