Sonic Touch products are developed with multiple technologies to remove the annoying whistle and squeal of feedback.
Adaptive Feedback Cancellation
The adaptive feedback cancellation algorithm used in Sonic Touch constantly monitors for changes in the environment that may cause feedback. When a change is detected, the phase canceling system quickly calculates and applies a “counter-signal” that removes the feedback without decreasing amplification.
Fixed Feedback Cancellation
Some environments—like listening to music or riding in a car—produce tonal sounds that adaptive systems can misinterpret as feedback. For these situations, Sonic Touch offers fixed feedback cancellation that is not susceptible to environmental tonal sounds.
Patient Controlled Retraining
Sonic Touch gives your patients the ability to “reset” the feedback canceller if there is a significant physical change in the feedback path.
