Application Notes

In this page you can find application notes on interesting room acoustics problems, where ODEON is used to provide reliable estimations. The application notes serve as guides for similar projects.

Detecting flutter echoes in ODEON, by A. Richard

This application note shows how to detect flutter echoes in a room model with different tools available in ODEON.

Modelling Simple Rooms in ODEON, by A. Richard

This application note presents the numerical and practical challenges posed by simple geometries in ODEON. The note focuses on one example of a flat rectangular room.

Modelling baffles in ODEON, by G. Koutsouris

In this application note we see different ways to model baffles inside ODEON – either with their full detail or as a large box around them.

Auralisation and how to calibrate the sound level for presentations, by J. H. Rindel

This is a guide on how to calibrate the sound level of an auralisation derived from a room acoustic simulation. The correct level of presentation is important for all kinds of auralisation in order to be as realistic as possible.

Orchestra simulation and auralisation, by  J. H. Rindel

This is a guide on how to simulate the sound of an orchestra in a room. The method is intended for concert halls and similar venues. Simulations may be used to compare the sound in different listener positions, to evaluate the balance between the instrument groups in a certain room design, or to compare the sound in a new hall design to that of another hall.

Calibration for Impulse Response Measurements, by G. Koutsouris and C.L. Christensen

This is a guide on how to calibrate the ODEON measuring system in order to obtain the Sound Strength (G) and Speech Transmission Index (STI) parameters. Calibration should be performed in a diffuse or an anechoic chamber. On top of that, a two-step calibration procedure is developed, which ensures that any change in the equipment gains does not destroy the calibration.

Measurements with a Smart Phone,  by C.L. Christensen and G. Koutsouris

This application note shows how to obtain “snap-shot” impulse response measurements for further analysis on a PC using a highly portable measurement equipment. When visiting a site, while taking a few snap-shots for documentation using the camera in the Smart phone, why not make a few acoustic snap-shots of the room at the same time?

Acoustics in Restaurants, by J. H. Rindel

This is a guide on how to calculate the ambient noise level in a space where the noise source is speech from a large number of people gathered and talking to each other in small groups. The field of application includes eating facilities like canteens, bars, and restaurants. Noise at receptions and similar social gatherings where people are standing may also be simulated. The method is not applicable to small spaces, i.e. a minimum of around 50 people is required for this method.
