2026-07-10 Acoustic Environment Measurement and Questionnaire Survey Data from the Second-Floor Dining Hall of Taizhou University Canteen doi:10.57760/sciencedb.41589 en This dataset contains acoustic measurement data and subjective questionnaire survey data collected from the second-floor dining hall of the student canteen at Taizhou University, Jiaojiang Campus, China. The data were collected between September 15, 2025 and January 10, 2026, as part of a comprehensive study on acoustic comfort in university canteens. The study integrates objective acoustic measurements, subjective user perception surveys, and simulation-based optimization.University canteens are high-density public dining spaces where excessive noise and reverberation can impair communication and dining comfort. This dataset was collected to:Assess the current acoustic environment (reverberation time and noise levels);Analyze the relationship between noise levels, crowd density, and spatial location;Understand diners’ subjective perceptions and preferences regarding the acoustic environment;Provide empirical evidence for acoustic optimization strategies.Measurement Data：This sheet contains time-series and spatial measurements of noise levels, crowd density counts, and reverberation time.Questionnaire Data：This sheet contains subjective evaluation data from 44 student diners.
