New Dubai airport terminal passes STI-PA measurements

test 24 August 2009

The speaker system includes approximately 4,000 ceiling loudspeakers, 600 passive arrays and about 140 active arrays. The large baggage claim hall is serviced by only 18 active DSP-controlled loudspeakers.

The intelligibility tests were masterminded by Rahe-Kraft’s Jakob Kraft, who said that the AL1 had proven to be “an indispensable help”.

“I was able to make several hundred STI-PA measurements in just one night only by myself,” he commented. “An operator in the main switch room enabled the STI-PA test signal from zone to zone, allowing me to verify the speech intelligibility at all assigned measurement positions. In Dubai I learnt to appreciate the Acoustilyzer for such onsite projects.”

NTi Audio’s Isabella Niffeler told II: “The success at Dubai airport is another prominent example where the Acoustilyzer AL1 emphasised its benefits by providing exactly the required set of tools for commissioning a very complex installation. Over years, our development engineers have carefully optimised and balanced the measurement capabilities of the instrument against a simple and robust user interface, leading to the worldwide success the instrument is enjoying now.”
