### The Sound-Pressure Levels
However, in a pairwise comparison, the difference in the L\({}_{\text{Aeq}}\) between the last two sessions (afternoon (16:30-18:30) and Evening (19:30-21:30)) was statistically not significant \(p>0.10\). \begin{table}

Table 2: The resultant equivalent sound-pressure levels in the small for the different locations, days of the week, and times of the day. Referring to the changes in the L\({}_{\text{Aeq}}\) according to the day of the week, the levels on Thursday and Friday are the highest. Thursdays are the last working day in the week, and many employees go out on this day with friends, for dining or for shopping, before heading home for the weekend. This is likely why Thursdays are more active. The repeated-measures ANOVA showed a significant difference in the L\({}_{\text{Aeq}}\) between the different days of the week, with \(p<0.001\) (F = 12.43). However, a detailed analysis for the different pairs of days showed that the most significant differences are found between Thursday and Friday, on the one hand, and between Monday, Tuesday, and Wednesday, on the other hand, with \(p<0.05\). Saturday and Sunday showed the lowest difference in L\({}_{\text{Aeq}}\) compared with the other days of the week. This can be explained by the relatively large number of customers in the early morning of Saturday doing shopping before the beginning of the new week, and the lower number of customers in the evening, as potential customers are at home, resting for the new week. On Sunday, in the early morning, the L\({}_{\text{Aeq}}\) was also higher due to the activities in the shops, such as cleaning and product arrangement for the new week. Figure 5 shows a sample measurement from the different locations on the evening sessions across the week. The increment in the L\({}_{\text{Aeq}}\) on Thursday and Friday is clear in comparison with other days of the week. The changes in L\({}_{\text{Aeq}}\) in the playing area and the food court over the week are more remarkable when compared with the entrances and the shopping areas. Figure 5 also shows the number of daily visitors over the whole week. The maximum increment in the number of visitors was on Thursday and Friday, which are the days with the maximum L\({}_{\text{Aeq}}\). During the measurement process, the background noise while the small was occupied was relatively high because of many sources, including continuous cleaning activities, the oscillators used in the area, the air-conditioning systems, and the different machines. This background noise may force the users of the mall to talk and interact louder [7].
