(Wydawnictwo Poznańskiego Towarzystwa Przyjaciół Nauk, 2005) Kubiak, Jarosław
Noise is on of the most important elements degrading man's living environment. It plays a significant role in the conditions of advanced urbanisation. Undertaken research is intended to establish its spatial distribution, change dynamics and modifications on the residential areas. Acoustic measurements were made on chosen residential quarter the city of Poznań. There are 46 points located among buildings. The measurements taken included: - recording the equivalent sound level (L,.,), - recording the minimum sound level (MINL), - recording the maximum sound level (MAXL). Such factors as air temperature, relative air humidity, wind velocity and wind direction was permanenet. Moreover, measurement were taken of the traffic noise, with studies made of its structure and level, in 4 places (they were selected cross-roads of the principal communication routes). The ultimate goal of the research is to draw an acoustic map.
