This study uses a tested laterite soil composition to investigate the acoustic properties of interlocking compressive stabilized earth blocks (ICSEBs) produced by the Nigerian Building and Road Research Institute (NBRRI). The laterite samples comprised 40.75% fines (silt-clay), 48.65% fine/medium/coarse, and 10.6% fine gravel. The ICSEBs produced from this composition were evaluated for their sound absorption coefficient values at octave bands of 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz. The results demonstrate that the ICSEBs exhibit favorable acoustic insulation properties, with sound absorption coefficients ranging from 0.71 to 0.99 at the tested frequencies. Comparative analysis with commonly used materials, such as fiber-glass insulation batts and acoustic plasterboard, highlights the competitive performance of the ICSEBs. This study emphasizes the need for further research to explore the influence of composition, thickness, and installation methods on the acoustic performance of ICSEBs, ensuring their suitability for specific applications. Meanwhile, the findings indicate that ICSEBs made from the laterite soil composition can be a cost-effective and durable solution for acoustic insulation in building construction. Therefore, this study provides valuable insight into the acoustic properties of ICSEB, which could be helpful for architects, engineers, and builders who seek to incorporate sustainable and cost-effective building materials in their projects.
