1.18.1 Masking Help/Automasking Quick Guide

Masking Help
Interacoustics masking help is available to make it easier to decide on a safe and correct masking intensity.
When masking help is activated, a status light on channel 2 indicates if masking is applied correctly.

Recommendations
•
Because several masking intensities will usually be correct, experienced audiologists are
recommended to use the masking help without displaying the recommended masking level.
•
When measuring the second ear, more information becomes available and it is not guaranteed that
the earlier measurements are still correct. By measuring the best ear first and completing air
conduction on both ears before measuring bone conduction, most errors can be avoided.
•
Clinicians do often not apply masking for bone conduction in the instance where the air-bone gap is
less than 10 dB in the better ear. Against general practice, masking help will always recommend that
masking is needed in these cases.
Automasking
Interacoustics auto masking is available to ease the effort required in order to mask with correct masking
levels. When auto masking is enabled, channel 2 is controlled by the system and is set to the appropriate
intensity level.

Masking help is activated by selecting the icon with the mask.
Gray indicates that the masking help is not active.
Green indicates that masking is correctly applied.
Optionally, the masking help can give a suggested masking level. The example
here shows that 85 dB, but also 75dB is in within the safe masking range.
Amber indicates that masking is recommended differently. There is either too
much or too little masking.
Purple indicates that masking would be recommended, but is practically
impossible.
Auto masking is activated by selecting the icon that shows the mask with letter A.
Green indicates that masking is correctly applied.
Amber indicates that masking is recommended louder and that extended range
needs to be activated to allow setting channel 2 to the correct level.
Purple indicates that masking would be needed, but is practically impossible.
