Abstract
A device configured to generate an air flow, the device including: a compressor; an air flow duct arranged to convey a flow of air generated by the compressor; a gas-filled cavity disposed beside the air flow duct; a wall separating the air flow duct and the cavity, the wall including at least one aperture; and an acoustic resistive screen covering and held in tension over the aperture of the wall. The screen is partially permeable and in fluid contact with air in the air flow duct and gas in the cavity and is configured to attenuate noise transmitted between the duct and the cavity. The resistive screen and the cavity together define a noise-damping resonator.
