Abstract:

Noise pollution monitoring in the Suceava Metropolitan Area (SvMA) continued in 2021 and 2022 during two campaigns (named 3 and 4). Sound level meters type CEM DT - 805 were used. In campaign 3, the average noise level recorded the highest values (over 60 dB) at the points near the main traffic arteries, E85, B-dul George Enescu, 1 Mai, intersection E85 with DN29A. During weekends, the noise level decreased by 10-15 dB compared to weekdays. At all monitoring points, there were diurnal fluctuations in noise levels: increases during the day (07.00-19.00) due to heavy road and pedestrian traffic and decreases during the night (22.00-06.00) due to reduced human activities. The difference between daytime and night-time noise levels was 20-25 dB in urban areas and 5-10 dB in peri-urban areas. In the fourth monitoring campaign, with indoor and outdoor, day and night observations, the average indoor noise level (20-30 dB) was 10-35 dB lower than outdoor (30-55 dB). Maximum noise levels were below 85 dB indoors and below 105 dB outdoors.
