Abstract:
This paper investigates sound insulation of building parts designed for low carbon emissions, focusing on the intersection of acoustic comfort and sustainability. As the construction industry increasingly adopts green building practices, driven by the need to mitigate climate change and reduce environmental impact, balancing energy efficiency with indoor comfort, including acoustic quality, becomes essential. Traditional soundproofing materials and methods often rely on high-carbon, non-renewable resources, like concrete slabs and walls, often due to cost reasons.This paper reviews current experimental and practical acoustical testing of sustainable building parts, e.g. walls and slabs, measured in our own lab as well as in-situ. Using case studies of certified green buildings, we examine how these approaches meet regulatory sound insulation standards and identify challenges and implementing low-carbon soundproofing solutions. Findings suggest that while low-carbon materials present viable options for sound insulation, optimizing both energy efficiency and acoustical performance requires integrated design approaches. The paper concludes with recommendations for future research and ideas for acoustically resilient and environmentally friendly building practices.
