Acoustics in ancient church, Hagia Sofia

The byzantine church Hagia Sofia was modelled as part of the CAHRISMA project. Hagia Sofias central dome is placed more than 50 metres above the floor, has a diameter of more than 31 m and is embraced by two half domes. The reverberation time is approximately 10 sec (1000 Hz).

Measurements were simulated with three sources in 12 receiver positions – here we are having a look around the room.

Below you may download an ODEON zip archive for the above example, which is a packaged ODEON model (for ODEON 15.15 Auditorium or Combined) containing all the necessary files to run it: material list, geometry, source and receiver placements, etc. ODEON zip archives may also contain the calculated jobs, however, the file below does not include the calculated jobs. You may find ODEON zip archives for other examples here.

To unzip an ODEON zip file:

  1. Launch ODEON
  2. Go to File > Zip > Unzip archive
  3. Select your downloaded ODEON zip file
  4. Select a folder to extract the files 
 

ODEON will then automatically load the room.
