[0001] The utility model relates to the technical field of noise detection, in particular to a noise testing tool. Background Art

[0002] Environmental noise refers to the sound generated in industrial production, construction, transportation and social life that interferes with the surrounding living environment. The impact of the acoustic environment is a sensory public nuisance because it depends not only on the noise intensity, but also on the behavioral state of the affected person at the time, and is related to the person's physiological and psychological factors; different people, or the same person in different behavioral states, will have different reactions to the same noise; the locality and dispersion of the impact of the acoustic environment are manifested in the following two aspects: first, any environmental noise source can only affect a certain range due to factors such as distance divergence attenuation, and people beyond a certain distance will not be affected by the sound source; second, the noise sources of the environment are dispersed, and it can be considered that the noise sources are everywhere, and people can be affected by noise in different locations.
