The effectiveness of concrete towards building acoustics improvement & noise reduction

Building acoustic is an important consideration in the design, operation and construction of most buildings, and can have a significant impact on health and wellbeing, communication and productivity. Concrete is a common building material which often faces challenges with sound absorption and noise transmission. Therefore, the aim of this research is to identify the most effective type of concrete for enhancing acoustic performance in buildings. By examining various concrete formulations and how its properties influence sound behaviour, this research will offer practical recommendations for concrete selection based on acoustic needs. Research shows that noise pollution, particularly in urban settings, can lead to adverse physical and psychological effects, making the need for enhanced acoustic design in buildings more urgent. Studies indicate that the degree of sound reflection in such modified concretes depends largely on specific aggregate types, pore size and distribution, and other changes in mix composition. By evaluating high-density, lightweight, and porous concrete, the research aims to close the gap between structural and acoustic efficiency. The methodology of this study based on secondary data such as literature reviews, academic report analysis and thematic analysis. Therefore, the aim of this research is to identify the most effective type of concrete for enhancing acoustic performance in buildings. By examining various concrete formulations and how its properties influence sound behavior, this research will offer practical recommendations for concrete selection based on acoustic needs.
