Abstract

Temporal structure of sound pressure level is
a key aspect at the time of characterizing
urban sound environments. In urban
agglomerations, environmental noise levels
fluctuate over a large range as a result of
the great complexity of these settings, with
considerable temporal and spatial
heterogeneity. Furthermore, the domain in
urban environments of noise sources, such
as road traffic, commercial or leisure
activities, construction works, etc., together
with the occurrence of sudden sound-level
maxima events (bells, sirens, vehicles at high
traffic speed, honking horns...), which are
quite frequent in urban agglomerations,
generate the appearance of very high values
of the impulsiveness of sound pressure level.
This aspect causes a great influence on the
time necessary for environmental noise
levels to become stabilized, which is a key
aspect for the accurate measurement,
interpretation and guarantee of a
statistically representative sample of a
given urban sound environment. Therefore,
the goal pursued in this work is to put forth a
procedure for the calculation of a value of
LAeq,T, representative of a certain urban
location in a short-term time period, from the
utilization of the value of the stabilization
time of the sound pressure level.
