sound absorption properties of wood plastic composite


Analysis of the sound absorption properties of the composites revealed that the noise reduction coefficient (NRC) of the CF/400 wt% SIR composite was the highest. Moreover the CF/SIR composites showed higher sound absorption efficiency (α) values at high frequencies than those of the CF/UPE composites. However the polymers had no effect on the NRC of the neat CFs when added in a low.【Get Price】

Sound absorption properties of wood plastic composites made.

WPCs with chamber structures had superior sound absorption properties at low and middle frequency range comparing to present commercial products. Higher surface roughness and density both benefit sound attenuation. However the effect of density towards sound energy dissipation would require further study on its microstructure.【Get Price】

Sound absorption of wood-based materials

From modern buildings to public spaces are made of concrete steel and glass. These materials increase propagation of sound and the reverberation time. Therefore furniture should be good sound absorbers in such places. The objective of this study was to ascertain acoustic properties of wood-based materials by determining normal acoustic impedance on the surface and sound absorption.【Get Price】

Recent advances in the sound insulation properties of bio.

The presence of calcium carbonate can increase stiffness of the composite providing better absorption of sound waves (Liang and Jiang 2012; Suhawati et al. 2013). The sound transmission loss of precipitated calcium carbonate (PCC)-filled wood plastic composite (WPC) was studied.【Get Price】

Evaluation of the Acoustic Properties of Wood-Plastic-Chalk.

Wood-plastic composites are a new group of materials that can be used in construction instead of wood and plastic. They are used in various industries due to features such as sound and water absorption among others. This article aims to study the acoustic properties of wood-plastic composites made of wood flour low-density polyethylene and chalk. In this study 6 combinations were made with.【Get Price】
