It is a challenge to achieve resonable speech intelligibillity in this large main hall with a reverberation time of 4 seconds. To see the achieved STI press next through this case-story.
You can also listen to the auralisation with the 20 array loudspeakers by scrolling further down this page.
 Most of the installed line arrays have 16 units like the one above and the four central line arrays have 32 units each. All line arrays have beam steering and different pre-delays of the Intellivox type.
Here you can find 3 multisource auralisation examples which illustrates how the system sounds in a central position (receiver 14) with ambient noise. 1 for a person speaking, 2 with only a remote array loudspeaker and 3 with the total designed array loudspeaker system. The 3 examples are also presented in this interview by the naked scientists.
