level dial

comparing the loudness of one frequency to another frequency.
✔✔Routine hearing testing should be performed: - ✔✔In a sound controlled
environment.
✔✔Audiometric zero is: - ✔✔0 dB Hearing Level
0 db HL
The level where normal ears can hear at every frequency.
✔✔In Pure Tone testing, threshold means: - ✔✔The lowest intensity the client hears
50% of the time.

frequencies than for 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 when a sound stops than when it begins.

thresholds.

conduction stimuli is: - ✔✔-Tympanometry
