Abstract

The resonator has a bent cone shape with rigid walls enclosing a gas volume which has a destructive interference effect on sound entering the resonator inlet. MECHANICAL ENGINEERING - The cross-sectional area (A) of the resonator reduces by a power of two over a distance x measured from the resonator inlet, according to the equation A=(1-x)2, where 1 is the length of the resonator from the inlet. A spiral or screw shaped resonator is used.
