“…[7][8][9][10][11][12] There are now many materials that can be derived from waste and biomass, such as wood, organic fibers of either plant or animal origin. [13][14][15][16][17] These materials can be used as sound-absorbing materials, and they have low environmental impacts and negative health effects. Examples of such materials include cellulose-based fibers derived from waste wood veneer and agriculture residues, such as cotton, hemp, and jute.…”

The subject of the present paper is improving sound absorption properties and protecting the dust generation of ceramic fiber boards. The two‐microphone impedance tube method measured the sound absorption coefficient (SAC) of ceramic fiberboards (CFB) with different shapes and sizes. The wood veneer was used to cover the ceramic fiberboard (VCFB) surface to improve the wall's appearance and prevent dust generation. The step‐shaped ceramic fiberboards with veneer attached (VCFBS) revealed improved SAC (0.98, 2000Hz) compared with CFB and VCFB. The noise reduction coefficient (NRC) and sound absorption average (SAA) showed a 100% improvement compared to CFB. The surface morphology and air permeability were analyzed using a scanning electron microscope and a capillary flow porometer to correlate with the findings. Furthermore, the porosity and pore diameter of the CFB were also studied to gain a comprehensive understanding of its acoustic properties and sound absorption capabilities. Statistical T‐tests revealed significant variations in the SAC (p ≤0.005). Besides, the obtained SAC was compared with other reported sound‐absorbing materials. These findings suggest that using step‐shaped ceramic fiberboard covered with a wood veneer can significantly absorb sound and improve the living environment. This novel approach offers potential advancements in sound‐absorbing materials for building construction.This article is protected by copyright. All rights reserved
