Abstract: A plurality of stationary noise sensors may each include a microphone to sense noise, a power source, and a communication device to transmit data about noise sensed by the microphone. A plurality of mobile noise sensors may each include a microphone to sense noise, a power source, and a communication device to transmit data about noise sensed by the microphone. A noise information hub may receive data from the stationary noise sensors and mobile noise sensors and provide indications associated with the received data via a cloud-based application. An analytics platform may receive the indications and analyze them to determine noise level exposure information for each of a plurality of locations within a workplace. The analytics platform may also transmit information to facilitate rendering of an interactive graphical operator interface that displays a map-based presentation of the noise level exposure information and prior noise-related results for each of the locations.
