✦ Synopsis

As is to be expected, there is a signoqcant negative correlation between room impression R and clarity C. The correlation.factor, rcR, is, however, only -0.77.

Therefore, these two quantities, R and C, must be separately defined, calculated and measured. The reverberation time leads to a certain anticipated value. The initial relqections lead, however, to signoqcant deviations from this anticipated value. These deviations, as opposed to the statistical distribution of sound in a room, give a reason .[or the good and poor seating positions in an auditorium.

It it possible to enhance both room impression and clarity when reflections arrive at the ear, either laterally or from the ceiling or the rear wall with a delay of 25 to 80 ms. The pairs of values of R and C in real concert halls group themselves around equal values of the ratios, f~,~,, of statistical energy arriving from the front to ambient statistical energy.for different reverberation times. Although the reverberation time in a room is a constant we see that [or different ratios of.frontal to ambient energy containing, as the)' do, the reflected energy, this is subjectively equivalent to a variation in reverberation time. In the middle of the auditorium the .frontal energy is higher and the impression clearer than would be expected on statistical distribution c~f energy grounds.
