Sound absorbing noise reduction assembly and method thereof

Abstract

The invention relates to a sound absorbing noise reduction assembly and a method thereof. The sound absorbing noise reduction assembly comprises multiple sound absorbing noise reduction assemblies which are arranged with intervals, wherein the sound absorbing noise reduction assemblies respectively have a casing and a sound eliminating chamber defined by the casing, the casings are respectively provided with a first surface and a second surface relative to the first surface, the first surfaces are respectively provided with multiple sound absorbing micro holes communicated with the sound eliminating chambers, and the second surface of the one sound absorbing noise reduction assembly is opposite to a first surface of the adjacent sound absorbing noise reduction assembly. Through the sound absorbing noise reduction assembly, when sound waves are reflected by the second surface of the one sound absorbing noise reduction assembly to the first surface of the adjacent sound absorbing noise reduction assembly, enter the sound eliminating chamber through the sound absorbing micro holes of the adjacent sound absorbing noise reduction assembly and are reflected in the sound eliminating chambers to realize sound absorbing noise reduction.

Description

technical field [0001] The present invention relates to a sound-absorbing and noise-reducing component and its method, especially to form a gap between each sound-absorbing and noise-reducing component to provide air circulation, and when the sound wave touches the sound-absorbing and noise-reducing component, it will enter the sound-absorbing cavity through the sound-absorbing micropore To reduce noise, so as to achieve the purpose of both sound absorption and noise reduction and ventilation. Background technique [0002] A commonly used sound insulation technology at present, such as the prior art disclosure of the "sound insulation wall" of Taiwan Bulletin No. M353224, includes a box body, a sound-absorbing cotton and a metal plate. There is an opening communicating with the hollow chamber on the body, the aforementioned sound-absorbing cotton is put into the hollow chamber of the aforementioned box body, the aforementioned metal plate cover is arranged on the aforementio...
