– In the
Tone
screen, when a point is stored, the noise level status from the last presentation of the stimulus is
stored.
A. Current noise status
B. Noise status at last stimulus - auto-
matically selected by OTOsuite -
will be stored with audiogram
point
– In the Speech screen, the noise level status is not assigned automatically because OTOsuite cannot judge if noise
registered after the stimulus is ambient noise or the patient's answer. You can use the Ambient Noise Assessor
dialog to keep an eye on the current noise level, and then present the stimulus when the status is OK (Green).
Then you can select the status in the dialog box before storing:
A. Current noise status
B. Noise status at last stimulus - selec-
ted by user - will be stored with
audiogram point
The selected status will be stored when you store a point in the audiogram.
2.14.4.3 Noise level indicators stored with measurements
Tone audiometry
When you make an audiogram using the Ambient Noise Assessor, the background color behind each point in the audi-
ogram indicates the following:
A. No background color: The noise level was below the
maximum permissible level.
B. Yellow: The measured ambient noise level was
above the maximum permissible noise level for the
stimulus. However, the level is so low that it may be
noise from the FreeFit itself, rather than ambient
noise. (See
Minimum HTL per transducer type ►
69 .)
C. Orange: The measured ambient noise was above the
maximum permissible noise level for the stimulus.
D. Gray: The status of ambient noise is unknown. Either
FreeFit was not activated when the point was meas-
ured, or the frequency was stored without the signal
having been presented.
