The article presents the study results of the of noise-like acoustic signals attenuation nature during propagation in urban environments. One of the Murom city territories representing a combination of a residential area, the location of educational institutions, and a machine-building enterprise was chosen for the study. A simulated complex noise-like signal and a sound amplification system with an audio signal power of 500 W were used as signal sources. The noise source was considered as a point source. The noise level values were recorded using a Class I ASSISTENT noise meter. For a more detailed analysis of the obtained results, data visualization using the QGIS geographic information system was provided. It was shown that, in general, the change in the acoustic signal attenuation is characteristic of quiet zones and tends to decrease fairly uniformly. At the same time, at 63 and 125 Hz frequencies, a deviation from the linearity of attenuation was detected, which may be associated with the influence of territorial factors or the an unaccounted short-term noise source existence.
