Abstract
Indicators explain the implementation state of noise assessment and management tools in
urban areas: Acoustic Classification Plan of Municipality; Noise Biennal Report, Noise
Abatement Plan
of Municipality; they also concern the control activities, carried on in
order to verify the compliance with noise limit values in force
:
Noise Controls, Exceeded
Regulatory limits, and the study of people exposed to noise levels: Studies on people
exposed to noise levels.
Considering the available data, referring to the 2014, Acoustic Classification Plan of
Municipality has been adopted in 58 of 85 cities considered, expressing a percentage of
68%. Noise Biennal Report on acoustic state of Municipaliy, mandatory for Municipalities
having more of 50.000 inhabitants, has been developed in 13 of 80 cities with a
population exceeding 50.000 inhabitants, considered in this Report, and Noise
Abatement Plan of Municipality has been approved in 14 cities of the 85 analized
cities.
Studies on people exposed to noise levels introduces studies carried out in accordance
with Directive 2002/49/EC requirements, and also studies carried out using other
methods. According to these assumptions, 33 cities have undertaken studies about the
people exposed to noise levels. The prevalent noise source in urban areas is the road
traffic, with a percentage of people exposed even more of 40%, referring to the noise
values ranges of Lden 65-69 dB(A).
Considering Noise Controls, wich show a decrease referred to the previous year (-
17%), 1.332 noise control activities have been carried out, 94% of which occurred
as a result of public complaints. Related to Exceeded Regulatory limits, 52% of the
inspections carried out have exceeded their regulatory limit values.
Slight deviations
have to be highlighted, compared with data of 2013, which show the persistence of a
state of insufficient implementation of legal instruments, while a decrease in control
activities must be underlined.
