Acoustic-Absorbing Property of Puncture-Resisting Textile Wall Coverings Composites

This study purposes to investigate acoustic absorbing and puncture resisting properties of wall covering composites with different number of layers, and then to construct prediction model of acoustic absorption coefficient. Puncture resistance linearly increases but maximum absorption coefficient shifts to lower frequency with number of layers.The acoustic absorbing property of wall covering composites presents porous acoustic-absorbing characteristic, and its prediction model correlates with critical frequency and maximum absorption coefficient. The resulting coverings have excellent puncture resistance and acoustic absorbing properties.
