Active protection of acoustic field of wanted sources from external noise in real time
We present the review of fundamental principles, the modern state and implemented applications of a new direction in the theory of mathematical modeling of devices for active protection of a subdomain from external noise in real time on the base of the difference potential method and the current acoustic exploring. The review is made in connection to the justification of our critical analysis of the recent Utyuzhnikov’s paper (S.V. Utyuzhnikov. Real-time active wave control with preservation of wanted field // IMA J. Appl. Mathematics, 2014, 79, 1126–1138).
