Analysis and Prediction of the Noise Reduction Coefficient of Lightlyneedled Estabragh/polypropylene Nonwovens Using Simplex Lattice Design
Abstract
This work aims to predict the noise reduction coefficient (NRC) of nonwoven layers produced from Estabragh/polypropylene blends of fibers. Estabragh is a natural hollow fiber which can be expected to have excellent sound insulation properties.
