Sound absorption properties of a low-density perforated date palm fibres panel

Research output: Contribution to journalArticle

Abstract

Sound absorption properties of a natural waste of a low density date palm fibre perforated panel have been presented. The measurements were carried out for a single layer sample using an impedance tube. A simulation was performed using Delany and Bazley model for the sound absorption coefficient for the single layer date palm fibre. The experiment was conducted for the panel with and without perforated plate facing. Three air gap thicknesses were used between the date palm fibre sample and the rigid backing of the impedance tube to study the effect of the air gap on the sound absorption. The results showed an improvement on the sound absorption coefficient at higher and lower frequency ranges when facing the panel with perforated plate. Further studies could be conducted to check the effect of different densities and perforations on the sound absorption of the date palm fibres.
