The absence of legislation for the control of noise emission levels is certainly
a problem, but the existence of a legislation inconsistent with the local conditions
that affect noise emission creates a false impression of action of the state. The
population and the environment suffer the consequences. On the other hand, instead
of speaking about a standard impossible to be met, the focus can be on the lack of
urban planning, which should adequate the noise sources (urban traffic, commercial
and services areas), so that the limit established by the local legislation could be
met in urban parks, that is, Leq = 55 dB(A) during daytime period.
