Abstract

The invention discloses a noise elimination device in public places. The noise elimination device in public places is characterized in that the device comprises acoustic panels which are vertically arranged on a base, sound absorbing layers which are made of sound absorbing materials are laid both on the front faces and the back faces of the acoustic panels, the acoustic panels are made of plastics, and the sound absorbing materials comprise glass wool, mineral wool, foamed plastics and felt or cotton fibers; the base is made of rubber materials. By the adoption of the noise elimination device in public places, noise in public places can be absorbed, the influence of the noise on the environment, the human physiology and the human psychology can be reduced, the device can be mounted temporarily, and moving is convenient.

Description

technical field [0001] The invention relates to a noise elimination device, in particular to a noise elimination device in public places. Background technique [0002] The known noise can be divided into low-frequency noise less than 400Hz, intermediate-frequency noise between 400-1000Hz and high-frequency noise greater than 1000Hz according to the sound frequency. In some public places, such as office halls, restaurants, etc., due to the lack of attention to noise elimination during interior decoration, smooth-surfaced decorative materials are often used, and the space is large without partitions, which will cause extreme noise in the interior space of the building. Noisy and chaotic, which has adverse effects on human physical and mental health. Contents of the invention [0003] The object of the present invention is to provide a noise elimination device for public places, which can absorb the noisy sound in public places, reduce the impact of noise on the environment,...
