An embedded real-time environmental noise monitoring device is designed for long-term monitoring of environmental noise and noise information processing. The STM32F407 is used as the processing core of the device. A microphone signal conditioning circuit is designed for signal amplification. The ADC embedded in the STM32 is used for signal acquisition. Simultaneously, a BeiDou GNSS module and a 5G module are integrated on the device, and these modules allow the device to upload noise location information, time information, and noise monitoring calculation results to a cloud server. The designed acquisition circuit's sensitivity is calibrated with a reference sound source. The findings of the tests indicate that the noise monitoring device that is designed has the capability to gather and analyze noise data in real-time while also satisfying the practical demands of environmental noise monitoring.
