Acoustic comfort in educational buildings and the impact of noise regulations in practice: An evaluation from legislation to performance

Ensuring acoustic comfort in educational environments is crucial for both pedagogical efficiency and user health. This study examines the acoustic performance of a newly constructed university research center in Türkiye, in line with the criteria set out in the “Regulation on the Protection of Buildings Against Noise.” Unlike most studies in the literature, which generally rely on post-occupancy measurements, this study offers a proactive evaluation method by integrating on-site environmental noise measurements ( L eq ) with detailed sound insulation simulations (KS Schallschutzrechner) in a building that is still under construction. Analyses show that, while the building’s location meets environmental noise limits (41–54 dBA), which is well below the 65 dBA threshold, the internal partition elements are insufficient to meet legal requirements. Quantitative findings reveal that using curtain wall systems ( R w : 33 dB) and MDF cabinets integrated into partition walls results in acoustic performance being approximately 10–15 dB below regulatory limits. Furthermore, excessive volume imbalances between corridors and workshops and the failure to design auditoriums as enclosed spaces were identified as the primary causes of acoustic failure. The study concludes with evidence-based design recommendations to bridge the gap between architectural design decisions and regulatory compliance, such as the use of high-performance laminated glass and optimized material placement. This research provides architects and consultants with a repeatable performance review model to ensure acoustic standards are met before completion of the building.
