Model Acoustics

Brüel & Kjær has launched a flexible, faster and more comprehensive version of room acoustic prediction software - ODEON 11.

This latest version enables users to perform their calculations twice as fast, as previously, with the addition of a new ray-radiation pattern based on the Fibonacci spiral. This spiral provides the same calculation precision, but with half the number of rays.

ODEON 11 also has multi-core support, allowing multiple grid calculation points to be processed simultaneously. The more cores, the faster calculations can be performed. With a quad-core processor, for example, grid processing will speed up by a factor five, as - combined with the new ray-tracing technique - job calculations will be ten times faster than they were previously.

Users can specify the parameters to be calculated and displayed for a certain project. Preferences can also be saved in user-defined templates. ODEON 11 combines this with a new, general way of defining room acoustic parameters, enabling expansion of the default set of parameters. This means if the exact parameter a user needs is not available, they can simply define it themselves.
