Project Description

The project aims to develop a low-cost feedback destroyer that reduces acoustic feedback caused by resonant frequencies in audio systems.

It addresses strong market demand and the high prices of available commercial feedback-destroyer products.

The prototype uses dedicated circuitry and digital notch-filter concepts to reduce unwanted acoustic feedback.
