Reflections of sound from waveguide terminations can play a major role in the performance of a random noise active attenuator. Their influence depends on the direction reflections propagate along the waveguide and on the configuration of the attenuator. Upstream and downstream reflections are theref

This paper describes theoretically the feedback effect of the secondary source on the primary source in a monopole system for active attenuation of noise in a duct, and gives a more accurate mathematical model Based on the model mentioned above, a new monopole system called the Analogue Compensating
