Abstract

A method for feeding pressurized air pulses to a quarter wave resonance tube, for generating a standing low-frequency sound wave in said quarter wave resonance tube. The method entails that the pressurized air pulses supply maximum input power to said standing low-frequency sound wave by feeding said pressurized air pulses only during the time intervals of the oscillation cycle when the air pressure in said rear end of the quarter wave resonance tube, is positive. Also disclosed is a revolving valve, for feeding pressurized air pulses to a quarter wave resonance tube, for generating a standing low-frequency sound wave in said quarter wave resonance tube.
