42 Reference positions throughout the Stadium
Within the seating area (capacity 8100 persons), Mr. Moon assigned 33 representative measurement points. A further 9 measurement points were selected on the field. The Minirator was connected to the audio system in the audio control room and generated the dedicated speech intelligibility test signal. The test signal was broadcasted throughout the stadium at the default announcement level. The XL2 simultaneously measured both the speech intelligibility and sound pressure level at the assigned locations. The append mode of the XL2 provides automated data recording mapped to the grid of measurement points.
