Feedback Optimization

Select the Feedback Optimization screen to run the feedback test.

1. Click the Start feedback test button for the device/ear you would like

to assess.

2. Follow the on-screen instructions to perform feedback optimization.

The status of the test appears above the graph (complete, incomplete,

not run). In cases where the environment may have impacted the test

(e.g., excess noise present), the final results include a combination of

measured values and predicted feedback threshold values. The status

then indicates Incomplete. Repeating the test will replace any predicted

values with measured values if they can be reliably obtained in the

current test environment.

Once the feedback test is completed, the hearing instrument’s gain is

limited as shown on the graph where:

• Black line = feedback threshold

• Grey line = hearing instrument gain limit

• Green line = target gain for 50 dB pure tone input

• Red or Blue line = aided gain for 50 dB pure tone input

Note: If desired, the feedback test can be deleted using the Delete

icon above the graph for the device / ear in question.

Note: The phase canceller is enabled prior to running the feedback

optimization test and the quick fit will be limited to the predicted

maximum stable gain. Following the feedback test, the device is

automatically quick fitted up to the desired adaptation manager level

setting, but not beyond the measured maximum stable gain curve.
