Abstract : The dependence of acoustic-transmission loss on the weight, thickness, and cover of woven fabrics is investigated over a broad range of frequencies. In actual fabrics, these variables are seldon independent of each other, so that their composite effect, in which cover has been shown to predominate, must be considered. In simulated models, in which these parameters are isolated, fabric weight and cover are shown theoretically to have a direct influence on transmission loss, whereas thickness appears to influence sound reduction inversely. These effects are especially evident at higher frequencies.
