    State of the art environmental noise monitoring systems are based on a digital signal processing. In general, they perform computation and storage of noise levels, spectral filtering, narrowband ... spectral analysis, evaluation of statistical indices, wave recordings, detection of noise events based on thresholds, and other similar tasks. Increase in processing power enabled the development of applications for noise measurements on smartphones. Some of them can provide surprisingly accurate results. Increase in processing power can be exploited to develop more sophisticated apparatus capable of complex processing of multichannel sound signals and other data. Therefore, a research has been carried out to develop three new measurement options for environmental noise monitoring systems; 1) automatic exclusion of uncorrelated noise events from measurements, 2) automatic identification of the dominant noise source location and 3) automatic classification of observed noise event. Implementation of these three features can reduce need for human resources, resulting in reduced costs and more accurate results. Presented technical solution exploits a synergy between these three options, implemented in an apparatus, which provides reliable results.
