SOUND ATTENUATING AIR VENT, SOUND ATTENUATING LINING AND METHOD OF PROVIDING A SOUND ATTENUATING AIR VENT

摘要

A sound attenuating air vent comprises: an air path and a discontinuous sound absorbing lining around at least a part of the air path. A method of designing such a sound attenuating air vent comprises: determining a target attenuation performance based on the noise source and the receiver noise sensitivity and the separating construction, and determining a desired arrangement for the discontinuous lining and/or vent based on the target attenuation performance.
