| Abstract | This paper examines trends from a parametric study that examined the transmission loss (TL) of simple cavity walls without framing. This paper is restricted to examining the effect associated with doubling the depth of a simple wall constructed from two sheets of 3 mm thick LEXAN (1.2 x 2.4 m. density 1183 kg/m3, and modulus of elasticity 4.8x10 9 Pa). The LEXAN wall specimen was placed in a filler wall that had a very much greater TL so no correction to the measured data was necessary. Fibrous material, when installed, was placed vertically (i.e., parellel to the LEXAN leaves) and was supported by thin wires to prevent the material from touching the leaves. The LEXAN was supported only at the perimeter, there was no framing interior to the cavity. Measured trends are compared to predictions from a lumped-impedance (T-Matrix) model to provide insight into the transmission mechanism(s). |
