Noise reduction effect adjustable device for sound insulation room

Abstract

The invention discloses a noise reduction effect adjustable device for a sound insulation room, and particularly relates to the field of sound insulation rooms. The noise reduction effect adjustable device comprises a shell, wherein a supporting plate is fixedly installed at the bottom of an inner cavity of the shell; a base plate groove is formed in the position, located in the inner cavity of the shell, of the top end of the supporting plate; a supporting bin is formed in the position, located in the inner cavity of the shell, of the top end of the base plate groove; a spring assembly is fixedly installed at the bottom of the supporting bin; a first sound insulation bin is formed in the position, located in the inner cavity of the shell, of the top end of the spring assembly; a second sound insulation bin is formed in the position, located in the inner cavity of the shell, of the top end of the first sound insulation bin; and a vacuum glass bin assembly is formed in the position, located in the inner cavity of the shell, of the top end of the second sound insulation bin. According to the noise reduction effect adjustable device, a sound insulation formwork is arranged, a cabin body where all sound insulation materials need to be stored is arranged inside the sound insulation formwork, then a handle is arranged at the top end of each sound insulation material, and therefore the sound insulation materials can be conveniently stored and collected; and a taking and placing opening is fixed through bolts, and therefore the sound insulation and noise reduction effects can be controlled and adjusted.

Description

technical field [0001] The invention relates to the technical field of soundproof rooms, and more specifically, the invention relates to a device with adjustable noise reduction effect in a soundproof room. Background technique [0002] The sound insulation room refers to a sound insulation test device designed for the product manufacturing workshop with test requirements. The sound absorption treatment is carried out in the sound insulation room to make it a small anechoic room. Some small products can be tested in the room, such as Precision instruments, electrical, audio and transformers, etc. [0003] There are following problems in existing technology: [0004] The sound insulation effect of the soundproof room is certain, but different products are installed in different locations, and the different locations also cause differences in the sound insulation effect of the location. Therefore, the soundproof room cannot actually simulate the sound insulation effect in dif...

AI Technical Summary

Problems solved by technology

[0004] The sound insulation effect of the soundproof room is certain, but different products are installed in different locations, and the different locations also cause differences in the sound insulation effect of the location. Therefore, the soundproof room cannot actually simulate the sound insulation effect in different environments, and due to The material of the soundproof room is determined, so it is not possible to test some products that require particularly good soundproofing effects
