  bibo_abstract:
  - Noise pollution in cities is recognized as a critical environmental threat, primarily
    caused by road traffic and other human activities in areas surrounded by sound-reflective
    infrastructure. 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.@eng
