MLD
The MLD test is another pre-defined test included with a dedicated screen and setup menu. The MLD
test is an optional function to the AC440 module and requires a separate license to be activated from
the menu of the application.
The term MLD corresponds to Masking Level Difference and refers to the improvement in intelligibility
(effective signal-to-noise) under noise conditions when a tone or speech is presented out of phase
rather than in phase. The patient is presented for both pure tone and noise concurrently while
conducting the test.
In the MLD test a Start/Stop button has been added to activate/deactivate the stimulus.
