Abstract

The invention discloses a device and a method of testing sound insulation and noise reduction of a wall material. The device comprises a base, an outer box, an inner box, a noise source, a first decibel meter and a second decibel meter, wherein the outer box, the inner box, the noise source, the first decibel meter and the second decibel meter are all put on the base, the inner box is arranged inthe center in the outer box, the top of the outer box is provided with a through hole, a to-be-tested wall material is coated on the inner wall of the inner box, the noise source is put in the centerin the inner box, the top of the inner box is provided with a handle, the handle penetrates the through hole and exposes out of the outer box, the first decibel meter is arranged between the outer boxand the inner box, the second decibel meter is arranged outside the outer box, and distances from the first decibel meter and the second decibel meter to the noise source are equal. The device of testing sound insulation and noise reduction of the wall material can test sound insulation and noise reduction of the wall material quantitatively, shows sound insulation and noise reduction of the wallmaterial in a data form, and is simple. The test method is easy to operate, is low-cost, and can detect a large quantity of samples rapidly and stably.

Description

technical field [0001] The invention relates to the technical field of material performance testing, and more specifically relates to a device and method for testing sound insulation and noise reduction of wall materials. Background technique [0002] With the rapid economic development and social progress, people's living standards are improving day by day. People began to have higher and higher requirements for the sound insulation and noise reduction performance of interior decoration wall materials. At present, the test of the sound insulation and noise reduction performance of interior decoration wall materials mainly relies on human subjective judgment after construction, and there is currently no technology for qualitative and quantitative testing. [0003] Therefore, how to quantitatively test the sound insulation and noise reduction performance of wall materials is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In ...
