ABSTRACT
Recently, obscurely disseminated work by Lehman has come to our attention that deduces a somewhat different overmoded enclosure power-flux distribution than the simple chi square result. This new formulation shows excellent agreement between theory and observation on the upper tail of distributions, which is where harmful effects will occur if they occur at all. The fit of the Lehman distribution to two sources of experimental data was undertaken to examine its applicability to reality. The power-flux probability density function inside a mode-stirred chamber at a fixed point and frequency is chi square with two degrees of freedom. The capability of the Lehman distribution, almost universally to fit data well at the highest values, obviously advocates its use in its present or enhanced form.
