Abstract

In this paper we describe minimum phase equalization techniques used to suppress acoustic oscillations in hearing aid systems. Acoustic feedback oscillations are a common problem associated with all public address systems and has been a major limiting factor in the design of a high quality hearing aids. The primary advantage of using minimum phase equalization techniques is that it cancels a substantial fraction of the open loop phase delay and makes it easy to use other techniques to suppress acoustic oscillations. Some design examples together with computer simulation results are also presented.
