Document Type and Number:
WIPO Patent Application WO/2023/181519
Kind Code:
A1
Abstract:
The present invention provides an air duct with a silencer capable of efficiently reducing sound to be propagated to an air-blowing destination in consideration of noise generated in the air duct when air is blown. An air duct with a silencer according to the present invention comprises: an air duct connected to an air-blowing source; and a silencer for reducing sound emitted from an outlet of the air duct. The primary silencing peak frequency of the silencer is lower than a frequency at which the intensity of sound generated in the air duct by air blowing within the air duct becomes maximum.
