Elmia concert hall

The 2nd Round Robin on Room Acoustical Computer Simulations was done in the Elmia Concert Hall in 2000. The demo shows the agreement beween measurements and simulations made in ODEON 9.1. A concert hall is a type of auditorium. Other examples of auditoriums are churches, mosques, opera halls, lecture halls or music studios.

Measurements were simulated in 12 source-receiver pairs – here the setup is shown from different angles.

As can be seen from previous slides, ODEON does a nice work in predicting room acoustics – at leisure time it plays billiards!
