The usual criterion of 10 % or less pressure reflection for lining materials of anechoic chambers is related to the real and imaginary parts of the specific acoustic impedance ratio, allowing some more direct relationship between the acoustic and physical properties of the lining material.
## Abstract The role of the product of the thermal properties of thermal conductivity and thermal capacity per unit volume in fire growth is explored in relation to a simple model of a room fire. The calculated differences between flashover times for two different lining materials are plausible; th
