摘要： Method and apparatus for increasing the turbulence in a gas exposed to low frequency sound. The gas is exposed to sound produced by a sound generator (10) which has a tubular resonator (11) having an open end and is operated at one of the resonance frequencies of the resonator having a maximum frequency of 150 Hz. The gas is flown into the tubular resonator through the open end thereof and is discharged from the resonator substantially in a region, where the sound pressure of the standing wave in the resonator has a node, after having passed through a substantial length of the resonator.
