Abstract

Noise pollution is a globally recognized problem impacting public health and quality of life. This study aimed to investigate effective noise-blocking methods using a soundproofing masonry cavity wall filled with gypsum boards. The experiments were conducted using small-scale built rooms, where sound was sourced and received to measure soundproofing efficiency. Various setups were assessed, including different thicknesses of gypsum boards combined with mineral wool and air gaps. The results revealed that adding gypsum boards can improve soundproofing; however, the improvement is marginal unless combined with additional materials. However, the combination of materials within the cavity, such as gypsum boards, mineral wool, and air gaps, provided better soundproofing, particularly in the frequency range of 500-8000 Hz. This integrated approach to filling the cavity proved more effective than using gypsum boards or air alone, offering a solution for noise reduction in masonry structures.
