As far as most of citizens complains are about noise coming from recreational activities,
usually related with the presence of people in the street around bars, pubs, parties and other
activities carried out in public spaces, it seems reasonable to include this kind of noise
source in the strategic noise maps, especially if the main objective of the noise mapping is to
draw action plans. A methodology is proposed to analyze that kind of noise environments
including short-term and long-term measurements, obtaining the acoustic indicators Ln and
Lden as well as number of people exposed to those indicators. The results obtained in six
different cities show that similar trends can be found for commercial streets in different cities,
showing an increase of 5 dBA in Leq between 5 p.m and 8 p.m compared to the average
value of Leq during the rest of day time. Night recreational noise seems more variable and an
in field study must be carried out. It has also been found that around 10% of population is
exposed to noise coming from commercial streets.
