Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a composite sound-absorbing material according to the present invention includes a sound-absorbing block body 1, and the sound-absorbing block body 1 includes a sound-absorbing bottom plate 2, a fiber density board 3, a secondary sound-absorbing board 4, a primary sound-absorbing board 5 and a sound-absorbing board 6. The front end of the sound-absorbing bottom plate 2 is provided with a fiber density board 3, and the front end of the fiber density board 3 is provided with a secondary sound-absorbing board 4 and a first-level sound-absorbing board 5, and the front end of the first-level sound-absorbing board 5 is a sound-absorbing board 6, so The sound-absorbing panel 6 is a grid structure.

[0017] The outer side of the sound-absorbing panel 6 is wavy.

[0018] The hole diameter of the first-stage sound-absorbing plate 5 is 50ppi, a...

Abstract

The invention relates to the technical field of materials and particularly relates to a composite silencing material which comprises a silencing block body, wherein the silencing block body comprises a silencing bottom board, a fiber density board, a second-level silencing board, a first-level silencing board and an acoustic board; the fiber density board is arranged at the front end of the silencing bottom board; the second-level silencing board and the first-level silencing board are arranged at the front end of the fiber density board; the acoustic board is arranged at the front end of the first-level silencing board; and the acoustic board is of a mesh structure. In the invention, since a three-level silencing structure is arranged in the silencing block body, a perfect hierarchical silencing effect can be realized; and the composite silencing material has the characteristics of convenience in use, easiness in operation, good practicability, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a composite sound-absorbing material. Background technique [0002] With the increase of equipment such as audio equipment, air conditioners, and television sets, environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Noise has the characteristics of locality, temporary and multiple. Noise will not only affect hearing, but also have adverse effects on people's cardiovascular system, nervous system, and endocrine system, so some people call noise a "deadly chronic poison". The physical and psychological harms that noise brings to people mainly include ① disturbing rest and sleep. Rest and sleep are necessary conditions for people to eliminate fatigue, restore physical strength and maintain health. But the noise is disturbing, making it difficult to rest and sleep. When people toss and turn an...
