The high prevalence of sleep disturbances among adolescents can negatively affect their concentration, psychological well-being, and academic performance, thereby requiring effective interventions to improve sleep quality. One commonly applied approach involves the use of auditory stimuli. This study aimed to analyze the effectiveness of digital sound-based therapy using delta binaural beats combined with white noise in enhancing adolescents’ sleep quality, measured with the Pittsburgh Sleep Quality Index (PSQI). A multigroup pretest–posttest experimental design was employed with three intervention groups: silence (S), white noise (WN), and delta binaural beats combined white noise (DWN). The interventions were conducted among 60 students of SMA Negeri 1 Bawang for 30 minutes before bedtime over seven consecutive days. Results showed an overall improvement in sleep quality, indicated by decreased PSQI scores across all groups. The S group demonstrated an average reduction of 2.40 points (24.87%), the WN group 2.00 points (20.94%), and the DWN group the highest at 2.60 points (26.26%). Statistical analysis also confirmed a significant group difference in PSQI score reduction (p = 0.039), with the DWN group ranked as the most effective. Moreover, the DWN group consistently improved both the proportion of respondents with “good” sleep quality and their average sleep duration. Although sound-based interventions show promising potential for improving sleep, further studies with larger samples, longer intervention periods, and additional EEG-based indicators are recommended.
