Problems solved by technology

[0002] In traditional acoustic applications, large-area sound-absorbing fillings and regular perforations are used as sound-absorbing constructions in the form of decoration on walls and ceilings. In practical applications, the sound is dry, which leads to language ability and sound reinforcement equipment cannot be adjusted normally, and the sound field is not balanced. Unreasonable location (missing frequency) problem

Abstract

The invention provides a full-range acoustic control module. The full-range acoustic control module is synthesized through sequentially packaging a panel layer with a two-dimensional acoustic atlas, afirst dustproof sound-transparent screen cloth layer, a first porous sound-absorbing cotton layer, a composite damping spacer layer, a second porous sound-absorbing cotton layer and a second dustproof sound-transparent screen cloth layer. The full-range acoustic control module has a sound field control advantage in all bands, particularly has good control ability performance at places with high sound pressure levels, is applicable to acoustical environments and spaces such as large-sized fields, airports, bullet trains, subway stations, theaters, conference centers, taping rooms, bars and industrial noise control and has good visual decoration and functional application.

Description

technical field [0001] The invention belongs to the technical field of architectural acoustics, and in particular relates to a full-frequency acoustic control module. Background technique [0002] In traditional acoustic applications, large-area sound-absorbing fillings and regular perforations are used for sound-absorbing construction in the form of decoration on walls and ceilings. In practical applications, the dry sound causes language ability and sound reinforcement equipment to be unable to debug normally, and the sound field is unbalanced. The problem of unreasonable position (missing frequency). Contents of the invention [0003] The purpose of the present invention is to provide a full-frequency acoustic control module to solve the above technical problems. [0004] The invention provides a full-frequency acoustic control module, which consists of a panel layer with a two-dimensional acoustic map, a first dust-proof and sound-permeable mesh layer, a first porous ...
