A single-board computer based distributed system for internal and external sound monitoring

  • 1 AGH university of Krakow, Poland


This work showcases a distributed noise monitoring system used for measuring noise levels both inside and outside of buildings in urban environments. The system utilises single board computers as main operating units which handle the measurement of parameters and communication. The noise monitoring stations can measure instantaneous and long-term acoustic noise levels, as well as atmospheric parameters such as atmospheric pressure, air temperature and humidity. Measurement stations are connected to an external server via the MQTT protocol. The external server allows for the recording of data into a secure database, as well as for providing end users with historical and instantaneous data on request. A test run of the measurement system was performed and has shown that the measurement stations can function in their design capacity. The system shows great promise in use in internal monitoring of industrial plants both as a precautionary measure for worker health and safety and as an easily modifiable sound monitoring platform in the industry 4.0 standard.
