The issue of noise transmission between residential units in high-rise buildings poses a significant challenge to privacy and auditory comfort, especially amid increasing urban expansion and population density. This study aims to address this problem by evaluating sound insulation strategies in high-rise residential units and assessing their alignment with international standards within local contexts. Six global residential projects were analyzed based on their adoption of advanced acoustic insulation solutions. The methodology involved examining key design elements such as the spatial distribution between quiet and noisy areas, and the use of insulation materials and techniques for walls, floors, ceilings, doors, and windows. Standardized indicators were used to assess the efficiency of these strategies, supported by statistical analysis. The results revealed varying levels of success in reducing noise transmission, with notable effectiveness in windows, ceilings, and floors where modern technologies and advanced materials were applied. The findings also highlight the importance of integrating sound insulation strategies during the early design stages to enhance auditory comfort in residential environments. The study recommends updating local acoustic standards and adopting more efficient design and technological solutions to achieve sustainable and comfortable residential settings.
