Problems solved by technology

[0004] In order to solve the problem that noise reduction and ventilation cannot be realized at the same time in the prior art, the present invention proposes a noise reduction crystal and a noise reduction wall, and the noise reduction effect is realized through the noise reduction crystal. The middle anechoic chamber and the side anechoic chamber are repeatedly refracted and reflected on the wall of the anechoic chamber when propagating, and the sound wave energy is attenuated to achieve the sound attenuation effect. A number of crystals are arranged to form a sound attenuation wall, which plays the role of sound attenuation or sound insulation. The solution can not only achieve ventilation and convection, but also achieve the effect of noise reduction (sound insulation), and also achieve light transmission

Abstract

The invention relates to a noise reducing crystal and a noise reducing wall. The noise reducing crystal comprises a horn mouth (1) and noise reducing chambers (2), the noise reducing chambers (2) comprise a middle noise reducing chamber (21) and at least one side noise reducing chambers (22), the middle noise reducing chamber (21) comprises a middle noise reducing chamber wall (212) and a middle noise reducing cavity (211), holes (213) are formed in the middle noise reducing wall (212), and the middle noise reducing cavity (211) is communicated with the horn mouth (1). Each side noise reducing chamber (22) comprises a side noise reducing chamber (221) and a side noise reducing wall (222), holes are formed in the bottoms of the side noise reducing walls (222), and a transition cavity (3) is formed between every two adjacent side noise reducing chambers (22). The noise reducing wall is composed of the noise reducing crystals through connecting parts (4). Noise can be effectively reduced, air can effectively circulate, and meanwhile the noise reducing wall can be manufactured to be transparent or opaque according to requirements. The noise reducing crystal is monomerically transported and assembled on site, more convenience is achieved, and limit of construction plant space is avoided.

Description

technical field [0001] The invention relates to a sound-absorbing crystal and a sound-absorbing wall, belonging to the field of noise treatment equipment. Background technique [0002] Dealing with noise in life has always been a difficult problem. The current method is nothing more than setting up obstacles for sound insulation. For example, the windows are made of two or three layers of glass, hollow, or laminated, etc., but the effect is not obvious, and the windows are closed. In order to have a sound insulation effect, the air convection is cut off, and it is impossible to achieve air circulation and sound insulation at the same time. [0003] Existing sound insulation measures are all to realize the effect of sound insulation or sound attenuation by arranging obstacles, utilizing obstacles to absorb sound waves or to block sound waves. Sound insulation and noise reduction through obstacles, first of all, the sound-absorbing materials are not transparent, not breathabl...
