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.
