Elimination of Ambient Noise
The GSI AudioStar Pro may be installed in a single room environment or as part
of a two room
suite.
Excessive noise in the test environment, such as that produced by conversation,
office equipment, or printers, reduces test validity because it tends to mask the
test signals. This is especially true at the lower frequencies where earphone
cushions provide less effective attenuation. A room that attenuates sound may be
required if ambient noise at the patient’s ears reaches levels sufficient to cause
apparent hearing loss at the lower frequencies.
The following table shows the maximum background levels that can be present
inside the room while a valid hearing test is being conducted. These values apply
for hearing threshold measurements to 0 dB HL.
