Evaluation methods, testing standards, and simulation techniques of sound absorption capabilities of cementitious materials: A review

Abstract

The growing challenge of noise pollution in urban environments necessitates effective strategies for sound management. This review paper explores the significance and capabilities of cementitious materials in sound absorption, highlighting their role in addressing noise pollution. The paper begins with an overview of sound and noise pollution, emphasizing their impact on human well-being. Various methods for measuring sound absorption are discussed, considering factors like material characteristics and application context. The review explores the modification of concrete with materials such as crumb rubber and lightweight aggregates, which enhance sound absorption properties while contributing to sustainable construction practices. It also examines the importance of balancing density, porosity, and surface area in achieving optimal acoustic performance in construction materials. Frequency analysis across different domains is crucial, with a specific focus on targeted frequency ranges in sound environments. Theoretical models and acoustic simulation methods are evaluated for their accuracy and applicability in analyzing sound absorption in porous materials. While cementitious materials show promise for sound absorption, challenges such as increased costs, reduced durability, and environmental impact must be addressed through collaborative research and a balanced approach. Finally, this review highlights the importance of adopting an interdisciplinary approach that integrates the expertise of acoustic scientists and material engineers to advance sound management. It emphasizes the need for solutions that are not only effective but also sustainable and practical in the face of the complexities of modern urban life.
