Sorry for any confusion and this video was posted for a customer who wanted to know what equipment was required for a sound insulation test, not really for public entertainment, so thanks to youtube for allowing this.

The microphone is approximately 1.4 m away from the dodecahedron speaker and the B&K2260 is 1.2m away from any reflecting surfaces, all conducted in accordinance with ISO 140 Part 4:1998. It appears to be closer due to the proximity of the dodecahedron speaker to the camera and the sound level meter being 1.4m behind the dodecahedron speaker.
