Abstract
Pulses are sensed at the inlet and outlet of a two-chamber reflective muffler and responsive thereto the cavities are tuned to the frequency of the pulses. Specifically, chamber walls are moved to have them located at spacings corresponding, respectively, to one half and one quarter of the wavelength of the pulses.
