Active Noise Cancellation (Anc) System Design Engineering K. C. Zangi

Optimal Feedback Control Formulation of the Active Noice Cancellation Problem: Pointwise and Distributed. Practical design is based on the concept of a continuously operating microphone (or group of microphones) sampling the enviornment and a speaker (or group of speakers) producing interfering waves that will cancel the noise. Applications include industrial work environments.
