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

This is a guide 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 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 in another hall.

 Calibration for Impulse Response Measurements, Part 3 - Two-step Method, by G. Koutsouris and C.L. Christensen

A hybrid calibration method is described which extends the ordinary diffuse-field and free-field methods, in order to correct for any accidental or incidental changes in the output or input gains.

 Calibration for Impulse Response Measurements, Part 2 - Free-field Method, by G. Koutsouris and C.L. Christensen

This is a guide on how to calibrate your system in order to obtain sound strength (G values) with the measuring system in ODEON. The free-field calibration method is described.

 ISO 3382-3 Open plan offices - Part 2 - Measurementsby J. H. Rindel

This is a guide how to measure the room acoustical parameters specially developed for open plan offices according to the international standard ISO 3382-3:2012 Acoustics – Measurement of room acoustic parameters – Part 3: Open plan offices

 Calculation of Speech Transmission Index in Roomsby J. H. Rindel

This is a guide how to use ODEON for calculating the speech transmission index in a room in accordance with the international standards IEC 60268-16 and ISO 9921.

 Calibration for Impulse Response Measurements, Part 1 - Diffuse-field Methodby G. Koutsouris and C.L. Christensen

This is a guide on how to calibrate your system in order to obtain sound strength (G values) with the measuring system in ODEON. The diffuse-field calibration method is described. 

  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 making a few acoustic snap-shots of the room at the same time?

 Acoustics in Restaurants, by J. H. Rindel

This is a guide 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 should be required for this method.
