## A survey of values of the inversion index (II) in a number of concert halls reveals large variations. Extreme values occur for stages of obviously quite different properties. Recent investigations have concentrated on the energy balance between direct sound energy and early refection energy for

β¦ Synopsis
To establish a definite list of the most important objective criteria for concert halls is not easy, but it is suggested that a group of four or five criteria may be sufficient to characterise, in general, the 'acoustics" of a specific hall. Comparing various concert halls by means of their measured objective criteria indicates that a rather simple method of ranking is feasible.

The diffraction properties o fan array of reflectors have been analyzed and the reflection characteristics are shown to divide into two frequency ranges. Below the limiting frequency of the single plates, the important parameter is the relative closed area of the reflector array. A t high frequencie
