WAVE DAMPING EFFECTS OF FIBROUS SCREENS

Expressions are derived for the damping of essentially translatory waves by screens prepared from fibrous materials such as aluminum wool, rubberized hair, and polyurethane foam. The derivations involve either the resistance coefficients or the permeabilities of these materials and these are individually determined. It is found that with the aluminum wool the damping is exponential and yields expressions admitting logarithmic decrements.
