The technique of map development of noise of the city on spectral characteristics of acoustic noise is offered. Cards of acoustic noise in the sound range of frequencies for the winter and summer season, and also the card of spatial distribution of a decay rate according to measurements in Tomsk are constructed. Empirical dependence of level of acoustic noise on transport loading for the winter and summer period is received.
The results of mapping the electric field in the city of Tomsk are discussed in the paper. Measurements were carried out in August 2013 in clear windless weather. The maps of distribution of electric field intensity at frequencies of 5-2000 Hz, at the industrial frequency of 50 Hz, at frequencies of 2-400 kHz and 10-30 kHz have been constructed.
The technique of mapping urban noise using spectral characteristics of acoustic noise is proposed. The acoustic noise in sound frequency range as well as spatial distribution of the decay rate is mapped using measurement data in Tomsk. The main sources of acoustic noise in the city have been identified. The empirical dependence of acoustic noise level on traffic load has been obtained.
