Methoden zur Messung der Diffusität in Hallräumen
In two earlier papers it was shown that a number of quantities that could be measured in a room, acoustically, were either not at all, or but loosely, related to the diffusion of the sound field. This paper attempts to make a constructive contribution to the measurement of diffusion. The diffusion is defined as the angular distribution of sound energy flux, in accordance with the definition that has found its visible expression in Meyer's and Thiele's “sound-hedgehog”. The problem is how, with sufficient angular accuracy and without disturbing the sound field noticeably, to make measurements in a reverberation chamber, the linear dimensions of which are comparable to the wavelength. It is solved by spectral analysis of the sound field at the measuring wall. The angular accuracy attained by this method is equivalent to that of an area antenna the dimensions of which considerably exceed those of the measuring wall.
