The first part of this work deals with the measurement of the directional distribution of incident sound at 2000 c/s in the large reverberation room of the III. Physikalisches Institut. The number of scattering objects in the room is taken as a parameter. It is shown that a diffuse sound field is achieved with a limited number of diffusors, even if one wall of the room is completely covered with a highly absorbent material.

The second part of this work deals with the dependence of the measured absorption coefficient on the geometric arrangement of the absorbent material. It was again found that correct results are only obtained, if the sound field is sufficiently diffuse and one wall is completely covered with the absorbent material; only in this case good agreement is found between the absorption coefficient measured in the reverberation room and the absorption coefficient calculated from impedance measurements with a Kundt tube.

Furthermore the sound level in the vicinity of the walls, especially at the edges and in the corners, is measured with the floor completely covered with absorbent material.
