Abstrakt: A system for the active suppression of sound with an open-loop feedback is described in relation to problems of the sound insulation of devices that radiate at discrete frequencies. Its principle of operation is based on creating a compensating field inverse to that of the primary source. The compensating field is formed at a monochromatic frequency that coincides with or is close to the frequency of the compensated signal. The efficiency and limiting capabilities of such a system are investigated. [ABSTRACT FROM AUTHOR]
