Research increasingly highlights the significant impact of building design on urban acoustics, as the outer surfaces of façades continuously interact with sound propagation. However, unlike interior acoustics, there are no regulations or standardized approaches for incorporating sound absorption to building exteriors, even in areas where noise levels exceed health recommendations. Façades with sound-absorptive properties, such as porous or multilayered materials, can achieve significant noise reductions compared to sound-reflective materials, which are the most common in cities and often amplify sound levels. This research aims to address this gap by presenting a systematic and practical approach to quantifying the frequency-based sound absorption coefficients of façades and classifying them into sound absorption classes in accordance with ISO 11654:1997. As part of this research, a series of practical tools for policymakers and practitioners has been developed, enabling the assessment of existing buildings and the design of new ones. This study advances progress toward healthier acoustic environments through proactive impact detection, sustainable design practices, and the promotion of urban resilience.","lang":"eng"}],"conference":{"end_date":"2025-08-27","name":"54th International Congress & Exposition on Noise Control Engineering","location":"Sao Paulo, Brazil","start_date":"2025-08-24"},"_id":"14071","author":[{"last_name":"Balderrama","full_name":"Balderrama, Alvaro","orcid":"0000-0002-4118-2838","id":"74171","first_name":"Alvaro"}],"ddc":["620"],"department":[{"_id":"DEP1634"}],"publication":"54th International Congress and Exposition on Noise Control Engineering"}
