Noise reducing screen

Abstract

The invention discloses a noise reducing screen, and relates to the technical field of screen structures. The noise reducing screen comprises a screen body and a screen frame. The screen body comprises a first outer-layer finish coat layer, first sound absorbing cotton, a sound insulation plate, second sound absorbing cotton and a second outer-layer finish coat layer which are arranged from the inside to the outside; the screen frame is used for installing and supporting the screen body. Reverberation in space can be reduced through the noise reducing screen, total reverberation time in the space is shortened, and the environment with short reverberation time and high speech articulation degree is created. Small spaces are partitioned in big space, the influence of adjacent small spaces and external noises is effectively reduced, a relative quiet acoustics microenvironment is created, language communication in the small spaces is convenient, and comfort of the acoustic environment is improved. When the small spaces are partitioned in the big space, the screen (a partition plate) can be divided and assembled to spread or be collected flexibly, transformation between small space partitioning and big space recovering can be flexibly achieved, and the two functions of screen moving and sound insulation and absorption are achieved.

Description

technical field [0001] The invention relates to the field of screen structures, in particular to a noise reduction screen. Background technique [0002] For large indoor spaces and large indoor open spaces, traditional screens are more for space separation, or space separation and visual aesthetic needs, with little consideration for acoustic treatment, and lack of design for a comfortable acoustic environment. ,Specifically in: [0003] (1) The traditional screen does not consider the sound insulation and sound absorption design of the screen body, basically does not have the ability to deal with acoustics, and has no noise reduction function; [0004] (2) When the large space is separated, the overall design lacks an overall acoustic design, and there is no sound-absorbing module in the large space, resulting in excessive reverberation in the room, low language clarity in the space, and extremely poor consideration of the acoustic environment treatment. The space is grea...

[0003] (1) The traditional screen does not consider the sound insulation and sound absorption design of the screen body, basically does not have the ability to deal with acoustics, and has no noise reduction function;

[0004] (2) When the large space is separated, the overall design lacks an overall acoustic design, and there is no sound-absorbing module in the large space, resulting in excessive reverberation in the room, low language clarity in the space, and extremely poor consideration of the acoustic environment treatment. The space is greatly affected by noise from other areas, and is greatly affected by the overall reverberation;
