Project MSensNet

The project was funded by the Central Innovation Program for SMEs (ZIM).

Project duration: June 2018 - May 2020

Project description

With previously applied methods for noise measurement, no reliable correlation of the measured noise level to the source to be identified is established. Within the MSensNet project, methods and technologies for sound immission measurement in outdoor areas were developed with the measurement and studio microphone manufacturer Microtech Gefell. In addition to the sound level measurement with weatherproof microphone units, an identification and thus a direction-dependent assignment of the measured noise level to the source could be carried out and correlated with meteorological sensor data in a real-time network in order to take existing cross-sensitivities into account.

For monitoring large-scale noise activity, such as traffic noise, decentrally located, weatherproof, networked microphone units with application-specific adaptable analog and digital signal processing including real-time networking should be developed.

Low-noise analog and high-resolution digital audio measurement technology is essential for mapping sound levels with very high dynamic range into electrical quantities. The deterministic and synchronized infrastructure of the large-scale device provides the basis for network-based transmission between noise monitoring stations.
