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.
what was the final db differentual from inside to out? also at 100 cycles?
thanks,
Marko

the microphone should be at least 1m away from your speaker.
