Hall Two is the most complex building of the three. Its shape is almost circular with a diameter of about 40 meters. It has 838 seats.

With regard to the design, it had to be considered that the interpreter booths at the back of the hall might cause some reduction in IR signal transmission due to shadow effects. In order to avoid the undesired loss of S/N level, it was decided that additional radiators should be placed at the rear wall. This solution was easily confirmed by the calculation.

Another fact to be considered was that the noise level could become quite high due to sunlight shining through the glass windows. EASE-IR allowed expected or worst-case noise values to be entered in order to simulate conditions that might occur for this application.

The installation today consists of 12 large radiators for the main area and another set of 4 small radiators to cover the space around the booths of the interpreters.
