produced by the audiometer and verifying that these
signals meet standard specifications
verifying output (which involves measuring each test
frequency at one intensity level) and verifying linearity
(which involves measuring multiple intensity levels at
one frequency). To check the output, the audiometer
acoustic calibration check is set to produce a 70 dB tone at each frequency, and
the sound level meter is used to make sure the output
is actually 70 dB. To check the linearity, the hearing
level dial is adjusted in 10 dB steps, and the sound
level meter is used to verify that the output actually
changes by 10 dB. The right and left earphones of
both the standard and insert headphones must be
checked individually. This must be accomplished at
the beginning and end of each stand.
