Abstract
PURPOSE: To provide a simple arrangement for silencing device, capable of enhancing its noise silencing effect, by forming air inlet and outlet openings respectively in adjacent two side walls of a box which is applied with a sound-absorbing material on its inner surface, forming a hollow space free of air flow at the corner portion of the above two side walls, and defining the hollow space by an air-flow deflecting plate.
CONSTITUTION: In the body 1 of a silencing device applied with sound-absorbing material 2 on its inner surface and formed with air inlet opening 3 and air outlet opening 4, an air-flow deflecting plate 5 is disposed at the corner portion of two side walls which are respectively formed with said air inlet opening 3 and air outlet opening 4. This air-flow deflecting plate 5 is disposed such that some clearance 6 is formed between the inner surface of sound-absorbing material 2 and the end portions of the same, and a hollow space 7 free of air flow is formed at the corner portion. Since, in operation of the above silencing device, hollow space 7 free of air flow serves as resonance silencer, low-frequency noises can be absorbed by appropriately selecting the dimension of clearance 6. Therefore, the noise silencing effect of the device can be enhance together with the noise absorbing effect of sound- absorbing material 2.
