This research examines sound absorption coefficient in porous concrete and coconut wood, suggesting implications for soundproofing materials in concert halls.
This article investigates the sound absorption mechanisms of porous concrete and coconut wood fibers, exploring the effects of factors such as porosity, coarse aggregate, and thickness on the sound absorption coefficient of porous concrete. It also examines the impact of different treatment methods on the sound absorption coefficient of coconut wood fibers. Through acoustic research on both porous concrete and coconut wood fibers, the feasibility of porous coconut wood concrete soundproofing materials is proposed. Based on the conclusions of the above analysis, the advantages and disadvantages of using porous coconut wood concrete soundproofing materials in concert halls are explored from multiple perspectives and dimensions.
