Abstract

The paper presents thesolution of designing the data collection module which is used in urban noisemonitoring system. The sound signal (noise level) is digitized using a soundsensor in combination with an analog - digital converter. The received data isthen processed by the average filter and calculated in dB by a microcontroller.Noise data is transmitted wirelessly to the data integration center using 4G transmission technology. The data integration center will process and provideonline noise level distribution map on the WebGIS environment. The obtainedtest results are compared with a noise level measuring device. This confirmedthe success of the proposed solution in this study.
