P. Vaidyanathan Efficient and successful communication of messages via imperfect channels is one of the major triumphs of information technology today. With more and more users desiring to share communication channels, the importance of clever exploitation of the bandwidth becomes paramount. A Microphone Array 26 for Hearing Aids by Bernard Widrow . This method enables the design of highly-directive-hearing in- struments which are comfortable, inconspicuous, and convenient to use. The array provides the user with a dramatic improvement in speech perception over existing hearing aid designs, particularly in the presence of background noise, reverberation, and feedback.
