Anechoic measurements (HRTFs)¶
Anechoic HRTFs from the KEMAR manikin with different distances¶

Fig. 35 Setup of the KEMAR in the anechoic chamber of TU Berlin.
HRTFs measured with a KEMAR dummy head in the anechoic chamber of the TU Berlin [Wierstorf2011]. The HRTFs were measured in the horizontal plane with a resolution of 1° for the three different distances of 0.5m, 1m, 2m, 3m.
Note, that for the distance of 0.5m the used Genelec loudspeaker presents not really a point source. In addition, the HRTFs for 0.5m include reflections of the sound going from the KEMAR head back to the loudspeaker and back to the dummy head.
The measurement comes also with the following headphone compensation filters:

Reverberant measurements (BRIRs)¶

The BRIRs are measured for three different sources and with a resolution of 1° and head movement from -90° to 90°. The measurement was done in two parts, which are shown in the following two figures. The measurement equipment was the same as described in [Wierstorf2011].

Fig. 38 Room sketch of the setup. The green crosses are the positions of the three loudspeakers that correspond to src4, src5, src6 in the BRIR file names.

The BRIRs are measured for three different sources and with a resolution of 1° and head movement from -90° to 90°. Note, that the photo of the room was not taken for the actual measurement setup. The measurement equipment was the same as described in [Wierstorf2011].
