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 otheractivities carried out in public spaces, it seems reasonable to include this kind of noisesource in the strategic noise maps, especially if the main objective of the noise mapping is todraw action plans. A methodology is proposed to analyze that kind of noise environmentsincluding short-term and long-term measurements, obtaining the acoustic indicators Ln andLden as well as number of people exposed to those indicators. The results obtained in sixdifferent 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 averagevalue of Leq during the rest of day time. Night recreational noise seems more variable and anin field study must be carried out. It has also been found that around 10% of population isexposed to noise coming from commercial streets. |
