Acoustic noise is one of the main factors affecting humans. The task of the urban environment operational monitoring is urgent as it will facilitate the solution of population protection problem. This problem can be solved by carrying out measurements in a full-spectrum mode with an assessment of the acoustic signal attenuation along typical noise propagation paths deep into residential areas. It has been shown that monitoring the noise level or its changes within the propagation limits deep into residential areas is possible provided that measuring microphones are located along this path at least in two characteristic points. An estimate of the potentially required microphone separation distance in case of using a system with two microphones is given. It is determined that at the preliminary stage of the measuring system construction, the measuring microphones’ location at a distance of 1 km from each other is sufficient. A block diagram of the meter, including two radio transmitters combined with the microphones and a receiver-analyzer, is proposed. It has been determined that acoustic signal delay on the way to the second microphone must be taken into account and the system calibration problem must be solved.
