A method and system for attenuating noise including arranging a plurality of accumulators () to form a transmittance path for compressible flow mass and noise between a noise source () and the external environment (), and selectively accumulating and confining compressible flow mass and noise within at least one of the plurality of accumulators, and attenuating noise confined within the at least one accumulator by ringdown. The system may include a plurality of interruptors/valves () which are operated at respective timings for periodically accumulating and confining compressible flow mass and noise in at least one of the plurality of accumulators.
