Experimental study of sound propagation in a street
Applied Acoustics, (2005)Abstract
This paper presents an experimental study of the sound propagation
in a street, performed during July 2002, in order to measure impulse
responses at numerous locations in a street canyon, and, for several
positions of the sound source. A specific attention has been paid
on the processing of the experimental data, in order to obtain accurate
values of the reverberation time and the steady-state sound pressure
level, including also the compensation of the atmospheric attenuation.
In total, 11 592 useful data have been collected during this experiment,
and are available by contacting the corresponding author. Reverberation
times and sound levels, in the narrow street, are then analyzed and
compared, for the 4 source positions in the street. This experimental
study gives interesting results on the behavior of the sound field
in the street
