Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
Feedback cancellationFeedback cancellationHigh-speed monitoring and control of feedback risk in individual processing channels.
Feedback CancellerFeedback CancellerGenesis AI took Starkey's industry-leading feedback cancellation system and improved it's specificity by adding vent optimization. Vent optimization measures the amount of sound leaking out the ear canal back to the hearing aid microphones. If the software predicted less leakage than the measurement shows (i.e. using an occluded dome that is not as occluding as you might like), Pro Fit will ask the professional if they would like to adjust gain measurements to compensate for the additional leakage. The reverse is true.
