Description

technical field [0001] The invention relates to the technical field of noise monitoring, in particular to a noise monitoring device, system and method. Background technique [0002] With the development of industrial production, transportation, and urban construction, as well as the increase of population density and the increase of household facilities (audio, air conditioning, television, etc.), environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Therefore, the monitoring of environmental noise has become a problem that people pay close attention to. Real-time noise spectrometer is an essential equipment for measuring and analyzing noise signals. It is a common tool for professional noise monitoring and audio signal research and application, and is widely used. [0003] The traditional analog audio spectrum analyzer has obvious disadvantages. The hardware implementation is complex, and ...
