Problems solved by technology

At present, the isolation and removal of noise is generally achieved by sound insulation panels. The current sound insulation panels generally include double-layer vacuum panels, sponge sound-absorbing panels, etc. Although these sound insulation panels can achieve sound insulation effects to a certain extent, their effects on noise pollution In more serious occasions, the sound insulation effect is not good, and the noise cannot be removed

Abstract

The invention discloses a noise eliminating device capable of improving noise eliminating effect greatly. Through the arrangement of a sound absorption damping module, acoustic wave energy of noise can be absorbed well and energy of noise is reduced. Then a vacuum layer is utilized for noise insulation and a micro-pore hole on the inner side absorbs sound further, so that influence of noise is reduced. The device provided by the invention is suitable for a condition with high noise removal requirements or with large noise, and achieves an excellent noise eliminating effect. At the same time, aspring is adopted for connecting the sound absorption damping module, so that the noise reduction capability of the sound absorption damping module is improved further.

Description

technical field [0001] The invention relates to a noise isolation device, which belongs to the technical field of noise elimination. Background technique [0002] Noise pollution refers to the phenomenon that the generated environmental noise exceeds the environmental noise emission standards stipulated by the state and interferes with the normal life, work and study of others. Environmental noise pollution is a kind of energy pollution. Like other industrial pollution, it is a public hazard that harms the human environment. At present, the isolation and removal of noise is generally realized by sound insulation boards. The current sound insulation boards generally include double-layer vacuum boards, sponge sound-absorbing boards, etc. Although these sound insulation boards can achieve sound insulation effect to a certain extent, they are not effective in noise pollution. In more serious cases, the sound insulation effect is not good, and the noise cannot be removed. [00...
