Description

Technical Field

[0001] The utility model relates to the technical field of environmental noise collection, in particular to a portable noise sampling device. Background Technique

[0002] Noise is a subjective evaluation criterion, that is, all sounds that affect others are noise. From the perspective of environmental protection, all sounds that affect people's normal study, work and rest, and all sounds that people "do not need" in certain occasions are collectively referred to as noise, such as the roar of machines, the motor sounds and whistles of various means of transportation, the noise of people, and various sudden sounds, etc., are all called noise. With the increasing severity of noise pollution, it is necessary to detect noise in order to better control noise pollution.

[0003] The detection of environmental noise is not only related to the environmental location, but also related to the height of a certain location. At present, to collect noise samples at a certain height at a certain place, people rely on climbing ladders manually, which is not only unsafe, but also the collected noise data is inaccurate. Although a lifting noise sampling device disclosed in Patent Application No. CN202020957436.0 solves the problem of height adjustment, the device structure is relatively cumbersome, and the floor area is relatively large, and it is not convenient to use. And a portable noise sampler disclosed in Application No. CN201720314577.9 is convenient to carry when in use, but the height position of its noise sampling is fixed, resulting in too single collected data and affecting data accuracy.
