Manual plotting
Audiograms can be performed by attachment of SA9 form to the front panel pins of the audiometer. Threshold points can be found by crossing the frequency and intensity lines Connecting the points by red or blue lines the air threshold curve will appear.
Noise elimination
The noise enclosure head-set of SA9 provides a high quality output intensity up to 70dB at
all frequencies as eliminating about 30dB of environment noise .
