Noisemap

Noisemap enables you to measure the noise level in your environment (as sound pressure Level (SPL) in dB(A)) and share it with the community . The collected/measured data will be transferred to the da_sense server at regular intervals, providing you with a crowdsourced noise meter. The community map can accessed at da_sense (www.da-sense.de).

In order to provide accurate data a calibration profile is needed.
Calibration is currently availble for the following phone models:
Samsung Nexus S, Samsung Galaxy Nexus, LG Nexus 4, LG Nexus 5, Samsung Galaxy S4, HTC One M8

We are working on making more calibration profiles available
