ODEON 12 released
The new ODEON 12 has several remarkable
features:
- A brand new option for measuring impulse
responses, deriving room acoustic parameters and comparing the results with
simulations; read more about this below.
- Support for the acoustic parameters in the new ISO 3382-3
standard, for open-plan offices (privacy distance, distraction distance and more); whether
data are simulated, measured or indeed both.
- Calculation of the IACC parameters (Inter-aural cross
correlation coefficients) as defined in ISO 3382-1 Annex B.
- Advanced tool for generation of series of sources or receivers
above an uneven surface.
- Automated level calibration helps aligning the level of
different source signals when performing auralisation with multiple
signals.
- Surface sources and line sources can now be defined with either
Lambert radiation or spherical radiation.
For more information about the news in version 12, see here.

Measurements
A brand
new, user-friendly and reliable room acoustical measuring system has been developed for ODEON
12. The ODEON measuring system can be used either together with a room model or as a stand-
alone tool. The impulse response is derived by deconvolution of sweep signals (linear or
exponential). The measuring system encompasses the following features:
- The swept-sine method is implemented in accordance with ISO 18233
Acoustics – Application of new measuring methods in building and room
acoustics
- Automatic detection of onset time of the impulse response.
- Automatic detection of noise floor individually per octave
band.
- Alternative option to use measured impulse responses generated with any
impulse sound source (pistol, hand clap, balloon etc.).
- Low-distortion and zero-phase octave band filtering in accordance with
the IEC 61260 (1995-08) standard.
- Correction for truncated energy as in ODEON simulations.
- Importing measured results to multi-point response for comparison with
simulations.
Measured squared impulse response with
automatic detection of noise floor, onset time and truncation time. |

Application Notes
A series of application notes is planned
in order to guide the ODEON users to simulations and measurements that are in agreement with
the international room acoustic standards, ISO 3382, ISO 14257, and IEC 60268-
16.
A new Application Note on simulations
following ISO 3382-3 Acoustics – Measurement of room acoustic parameters – Part 3:
Open plan offices is available for download here.
In the near future other application notes in this series will
appear.

ODEON
future points of contact
After eleven years of cooperation with Brüel
& Kjær this has been brought to an end in a mutual understanding. In the future you
will be supported directly from the ODEON experts at: support@odeon.dk. In some parts of the world Odeon A/S will
establish connections to new local dealers, but in general our customers should contact us
directly at: sales@odeon.dk.
