Sensory evaluation methods have been predominantly developed in food and wine industry to explore the perceptual characteristics of products, which are hard to evaluate through consumer based preference methods due to huge variation in individual tastes.

The acoustics of concert halls is also heavily influenced by a matter of taste. Therefore, sensory evaluation methods are very useful for studying auditorium acoustics due to their ability to extract information often hidden behind preference judgements.

On this page you find data on directivities of symphony orchestra instruments.

A Matlab GUI for analyzing instrument directivities

The registered users can download from the link below a Matlab package, which contains an interactive GUI for visualization directivities of all common symphony orchestra instruments. The GUI is initialized and started by running the script 'startGui.m'. See also README.TXT for more information. The presented measurement system as well as analysis of all instruments are presented in

This is the system described in the December 2008 issue of Acta Acustica United with Acustica.

Anechoic recordings are needed in auralization. We have just finished a project in which we recorded symphony orchestra musicians one by one in an anechoic chamber. The recordings (instruments on individual tracks) are publicly available on downloads page. On these pages you can find information about the recording process as well as some examples.

We gave a 3-hour tutorial on room acoustic modeling at the 124th convention of the Audio Engineering Society in Amsterdam on May 18th, 2008. Please, find in the attachments the presentation slides we used. The accompanying software will be made available as well after some polishing.
