The origin of controlling feedback in hearing aids begins with their very creation. Feedback is created when sound from the hearing aid is heard by the microphone and increases in volume, leading to a high-pitched squeal. To fix this, many methods of feedback management have been used.
Digital Signal Processing algorithms are one way of managing feedback. They observe the sound input and make modifications to prevent feedback from happening. This helps the user to hear clearly and comfortably.
Adaptive feedback cancellation systems are also employed. These keep watch of the sound output and alter the hearing aid settings to stop feedback. This adaptive process lets for changes in real-time, maximizing the user's experience.
Moreover, progress in hearing aid design has impacted feedback management. Improved microphone placement and housing designs help reduce feedback. When sound has less chance of escaping and entering the microphones, feedback is reduced.
