Odeon – A Hybrid Computer Model for Room Acoustic Modelling
Computer Modelling of Sound Fields in Rooms – the State of the Art and Outlook to the Future
Treatment of Early and Late Reflections in a Hybrid Computer Model for Room Acoustics
The ODEON computer model for acoustics in large rooms is intended for use both in design (by predicting room acoustical indices quickly and easily) and in research (by forming the basis of an auralization system and promoting the study of various room acoustical phenomena). These conflicting demands preclude the use of either ‘pure’ image source […]
Predicting Room Acoustical Behaviour with the ODEON Computer Model
The ODEON model for room acoustics is implemented for general use on a PC. Technical features of the program relevant to the acoustical design process include interactive visualizations of reflection paths and sequences, mapping of overall energy distributions and of coverage provided by individual reflectors, and minimized recalculation times. In this paper the modelling process […]
The Use of a Digital Audio Mainframe for Room Acoustical Auralization
A new user-friendly method for auralization has been developed by interfacing a digital audio mainframe and a room acoustical computer model. Instead of using a convolution technique, early reflections are created by time delays and late reflections by an electronic reverberation processor. The system is verified through measurements of a number of room acoustical parameters […]
How to use your Ears in Room Acoustical Design
Combining a Computer Model and Commercial Sound Studio Hardware for on-line ‘sketch’ Auralization
Room Acoustical Designing with a Computer Model and an Audio Mainframe for Auralization
Computer models for simulation of the acoustics of rooms have become useful tools for acoustic consultants and researchers. The calculated reflectogram and decay curve represents the acoustical characteristics of a particular receiving point in a particular room, and this information may be used for auralization, ie to make the result audible. his new technique allows […]
An Auralization Tool for studying the Interaction between Room and Music
Modelling Sound Distribution Systems in Room Acoustical Computer Model
A method for modelling sound distribution systems, using multiple electroacoustic sources is described. The method implies not only source-directivity, -gain, -equalization, and -delay, but also room geometry as well as absorption- and diffusion-coefficients for the surface materials. Room acoustical calculations for a large cathedral are presented, visually by mapping of parameters, reflectograms, reflection paths, and […]
