Description

Technical Field

[0001] The utility model relates to the technical field of noise detection, in particular to a noise detection device used in an urban environment. Background Art

[0002] Noise pollution is a major pollution problem in cities. Noise detection on urban road traffic can obtain noise data so that appropriate measures can be taken to control the noise.

[0003] When the existing noise detection device is used, the angle and height of the noise detection device are generally fixed, and it is difficult to adjust according to the changes in the noise source in the surrounding environment. When the direction of the noise source changes, the noise detection device is turned away from the noise source, which easily reduces the intensity of the noise during noise detection. For example, it is easy for a person's ears to be turned toward the noise source to hear clearly. If a person's ears are turned away from the noise source, the volume heard is much smaller than that heard when the ears are turned toward the noise source. Therefore, the noise detection effect is easily reduced. Utility Model Content
