System composition
The system is equipped with noise measurement modules that operate based on equivalent noise levels and subjective annoyance, enabling the automatic online monitoring of ambient sound equivalent levels and ambient noise levels (noise values based on human subjective annoyance and excluding the influence of natural sound sources). Additionally, the system can be expanded with modules for video surveillance, meteorology, and traffic flow recording.
