Upon completion of a test recording, a colored Aided Audibar shows the SII for the aided average speech signal.
The difference between the unaided and aided SII score (and the associated length of their respective 'Audibars')
visually quantifies the speech intelligibility improvement for soft speech likely provided by the hearing
instrument being fit. To further demonstrate the improvement, the unaided speech 'banana' may be displayed by
clicking
beside the Unaided Audibar.
Adjusting the Maximum Output Level
See Speechmap screen choices for setup and audiometric data entry. See Using Speechmap.
Follow the instructions in Speechmap screen choices to enter audiometric data and select the fitting rule.
1. Click in the 3 area to start the third test. Once the test is started, click the [Stimulus] list button to select
the stimulus type as MPO. When you start a new test, the speech envelope of the previous test may be
automatically hidden. See Speechmap Setup to change this behaviour. To change the default stimulus type
and level see Saving test setup.
2. In Test box mode, while the 90 dB sweep is being presented, adjust the hearing instrument's high-level gain
and/or output limiting (e.g. MPO, PC) so that the curve matches the + REAR90 targets (DSL) or approaches
but does not exceed the UCL estimates (*) at all frequencies.
3. Click to run and store a complete sweep. Repeat as necessary.
