[0001] The utility model relates to the technical field of noise testing, in particular to a multi-point noise testing frame. Background Art

[0002] The so-called noise is the sound with irregular and chaotic changes in the frequency and strength of the sound waves. From a physiological point of view, it is the sound that hinders people's normal rest, study and work, and the sound that interferes with the sound people want to hear. The possible sources of noise are airplanes, cars, factories, construction sites, daily life, etc. Noise is one of the environmental pollution. Governments of various countries generally have corresponding laws and regulations to control noise. High decibel noise can even cause serious damage to the eardrum of the human body, leading to deafness, etc. The use of noise tester can provide the decibel reached by the noise so as to take relevant measures to control and reduce the noise.

[0003] The Chinese patent with the announcement number CN202023319181.4 currently discloses a construction site noise monitoring device.

In addition, when the above-mentioned device is in use, it is not conducive to multi-point limit installation of the noise monitoring equipment, affecting the effect of noise monitoring in different directions. Therefore, we need to provide a construction site noise monitoring device. Utility Model Content
