Abstract
A method and apparatus for matching or balancing average signal levels between at least two input signal channels and their respective microphone elements so as to allow a hearing aid or instrument to maintain optimum directional characteristics over time are provided. The hearing aid may comprise an analogue signal processor or a digital signal processor adapted for controlling characteristics, e.g., gain and/or frequency response, of one or more of the input signal channels.
