Abstract

PURPOSE: To prevent noise from transmitting to the other area by attaching an air permeable noise insulating shell in the way of an air duct.
CONSTITUTION: A center-throughing noise insulating material 2 air-permeable like glass wool is put in a non-air-permeable case 1 made of plastic resin whose both ends 5, 6 are connected with air ducts 4, 4 through which air flows. The interior diameter d1 of the noise insulating material pipe 2 is approximately equal to the inner diameter d2 of the pipe 4. To prevent dust from lodging on the noise insulating material 2, a filter film 3 of non-woven fabric is attached on the inner face of the noise insulating material pipe through which air flows.
