2.4 The Masking Assistant
If the Masking Assistant is enabled, it will at all times check for frequencies that may require testing with
masking. This also applies to old audiograms imported from NOAH or XML as long as a supported transducer
was stored with the data.
The Masking Assistant is a tool provided to help you with an indication that there may be frequencies where testing with
masking
1
is recommended.
• The audiogram symbol will flash at the specific frequencies where contralateral masking may be recommended
2
.
• The masking criteria are configurable so that you can
set them up to match your local recommendations for
masking. You can for instance choose either frequency
specific criteria, which increases the efficacy of your
work, or the traditional "one-level-fits-all" criteria.
Select the Tools > Configuration Wizard > Audi-
ometry - Configure ... > Masking Assistant to set up
the masking criteria.
All masking signals are calibrated in effective masking.
