Table 3: Compared arithmetic means of acoustic variables according to the areas analysed (ANOVA analysis: * significant differences \(p\) < 0.05). The equivalent sound levels measured on Paseo del Arenal were in the range of 58.9 and 69.2 dBA, with the highest level recorded in the playground area (1.1). In contrast, the lowest level was recorded in the tree zone (1.2). Plaza Nueva (2.1-2.3) was considered the most artificial space of those studied. It was divided into three places: the arcade where there is a high number of bars; the terrace area which is often occupied by tables from the bars and musicians; and the central area, where children play. The noisiest zone was the arcade, where values in the range of 61.6-72.1 dBA were recorded, probably due to the reverberating effect. The lowest sound levels were registered in Plaza Levante (3.1), ranging between 56.6 and 62.7 dBA. The LA\({}_{\text{eq,10 min}}\) levels registered in Plaza San Pedro Deusto (4.1) varied from 64.2 dBA to 66.9 dBA. In Plaza General Latorre (5.1 and 5.2) noise measurements were taken both before and after its renovation.
