Sources and Receivers

All acoustical simulations in ODEON need at least one sound source. The different editions include different source types.

  • Odeon Basics includes point sources only
  • Odeon Industrial includes point, line and surface sources
  • Odeon Auditorium includes point and array sources
  • Odeon Combined includes all type of sources

Point, line, & multi-surface sources

Point sources can be assigned a directivity balloon and sound power by octave bands. Sources and receivers can be tabulated into an array.

Line sources and multi-surface sources are available in editions Industrial and Combined. Line sources are useful to model long sources like pipes with running water and conveyor belts, while multi-surfaces are useful to model large industrial machinery.

Source Group Editor

The Source Group Editor allows you to apply changes to many sources at once, from adjusting level or orientation, to rotating or translating sources using reference points.

Loudspeaker array sources

ODEON Auditorium and Combined allow you to define individual transducers in an array source, including their position, delay, and directivity. ODEON then produces the directivity for the full array.

Directivity Editor

In ODEON, you can create and edit your own custom directivity balloons.
