Abstract

This study explores the acoustic absorption and thermal insulation properties of corn husk fiber (CHF) as a sustainable construction material. The results show impressive noise reduction coefficients (0.36-0.60) and effective thermal conductivities (0.038-0.042) for CHF. Notably, CHF's thermal insulation remains unaffected by moisture content. The research employs the Dunn and Davern (DD) model and an optimized DD model using the Nelder-Mead simplex algorithm, with the latter providing highly accurate acoustic predictions. These findings highlight the potential of CHF as an eco-friendly and efficient material for sound absorption and thermal insulation in construction. © 2023 Canadian Acoustical Association.
