Ecological Noise Automatic Monitoring System

  • Description:The ecological noise automatic monitoring system is an ecological noise measurement device based on the perception of irritability. The system configuration is based on the noise measurement module based on the equivalent sound level and the noise measurement module based on the subjective irritability, which realizes the automatic online monitoring of the equivalent sound level of the ambient sound and the ambient noise level (based on the subjective irritability of the human body and the noise value after removing the influence of the natural sound source). At the same time, it can be extended with video monitoring modules, meteorological modules, traffic flow recording modules, etc.

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.
