“…A field survey conducted among 300 students in Egypt revealed that more than half of the students thought classroom background sounds disturbed their peace of mind, and 37% contended that those sounds made them angry/upset [7]. Recently, more studies have been inclined to focus on the dichotomous outcomes (i.e., positive or negative impacts) of sounds on individuals [26,27]. For example, Jiang et al [28] conducted experiments in a controlled environment by playing audio clips that included four background sounds (i.e., none, traffic, nature, and mechanical sounds).…”

This study investigated the impacts of students’ mood states and background sound levels on students’ sound perceptions and academic performance in four library rooms. The background sound level was measured for five days. Meanwhile, around 300 students were invited to participate in a survey of questions about their acoustic perceptions and mood states and a concentration test. Pearson correlation, one-way ANOVA, and two-way ANOVA were applied to establish the relationships between the LAeq, students’ mood states, acoustic perceptions, and concentration levels on both the individual level and the room level and to identify the interaction effect between the background sound levels and mood states on students’ acoustic perception and concentration. The results indicated that LAeq in learning spaces significantly impacted students’ acoustic satisfaction, but only at the room level. In contrast, mood states mainly influenced students’ sound perception and concentration at the individual level. Furthermore, this study reports significant interaction effects between mood state and LAeq on students’ sound perceptions and reveals different impacts of mood states due to different sound levels. These results could help improve occupants’ acoustic perceptions and performance in learning spaces in the future.
