Over the past decade, signal processing for industrial hearing aids has evolved from analog electronics for amplitude compression to sophisticated digital systems that integrate multiple adaptive algorithms for beamforming, feedback cancellation, amplitude compression, noise reduction and signal quality enhancement. Commonly, these modules are designed independently and consequently the opportunities for undesired interactive effects are abound. In this paper we present an approach to integrate adaptive modules for amplification, amplitude compression, noise reduction and signal quality (distortion) control.
