Indoor noise reduction device

Abstract

An indoor noise reduction device relates to the noise reduction equipment technology field. The invention relates to the indoor noise reduction device. The device comprises a filter layer, a vacuum glass layer, an airbag layer and a damping layer. The filter layer is connected to the vacuum glass layer. The vacuum glass layer is connected to the airbag layer. The airbag layer is connected to the damping layer. The filter layer comprises a noise reduction plate and a honeycomb paper base. The noise reduction plate is pasted to the outer side of the honeycomb paper base through a binder. The airbag layer comprises a sound insulation plate and buffer airbags. The sound insulation plate is provided with the plurality of buffer airbags. The buffer airbags are in a round table shape and noise reduction filling materials are filled in the buffer airbags. The internal portion of the damping layer is provided with a damping rubber. The device can be simply and conveniently installed. Through the four kinds of noise reduction processing of the filter layer, the vacuum glass layer, the airbag layer and the damping layer, sound insulation, absorption and obstruction can be effectively performed on a noise. The indoor noise can be effectively reduced and a quiet and comfortable living condition is built for a user.

Description

technical field [0001] The invention relates to the technical field of noise reduction equipment, in particular to an indoor noise reduction device. Background technique [0002] Noise pollution, air pollution, water pollution and solid waste pollution have been listed as the four major environmental hazards in today's society. Especially when excessive exposure to noise pollution will not only make people feel irritable, seriously affect sleep and mental health, but also cause diseases such as learning disabilities and tinnitus, and even increase the risk of heart disease and other diseases, thereby reducing people's life expectancy. Therefore, how to reduce noise pollution has become one of the main issues of environmental pollution control under the new situation of the 21st century. [0003] The current indoor noise reduction devices depend on the level of frequency resolution of noise sources and the dependence on high-precision electronic components, which will cause ...

AI Technical Summary

Problems solved by technology

[0003] The current indoor noise reduction devices depend on the level of frequency resolution of noise sources and the dependence on high-precision electronic components, which will cause the existing devices to fail when they encounter complex multi-frequency, time-varying and noise containing secondary sources. will be greatly reduced; and the expensive cost also narrows the applicable field, so that it cannot meet the needs of daily indoor noise control
