SoundMap Feedback Canceller
Audible feedback, which manifests itself as a typical loud whistling sound, is something no one likes to hear. Yet feedback is a risk in any hearing instrument, due to the proximity of the speaker and the microphones.
SoundMap Feedback Canceller uses a new approach to detect and cancel feedback. It makes Philips HearLink a very stable instrument delivering optimal audiological benefits to the users and gives hearing care professionals more flexibility to fit Philips HearLink.
Good feedback management works like the foundation of a house – you can’t see it, but without it the house won’t stand. Or, in other words, without SoundMap Feedback Canceller, Philips HearLink users won’t get the benefits of SoundMap Amplification and Noise Control.
To ensure its stability, Philips HearLink uses SoundMap Feedback Canceller, which marks a breakthrough in anti-feedback management. While traditional systems can detect feedback, SoundMap is fast enough to detect the early build-up of feedback.
