ABSTRACT:
A double throat tuner including a second conduit concentric to a first conduit which connects the gas flow to a first volume tuning chamber having a first effective volume. The radial difference between the first and second conduits and the length of overlap of the first and second conduits in combination with the effective volume of the first tuning chamber attenuates a preselective frequency of sound. This attenuation is for a specific frequency range in addition to the overall attenuation of the complete system including a plurality of conduits serially connected by a respective chamber.
