Abstract
A sound system design/simulation system provides a more realistic simulation of an existing venue by matching a measured reverberation characteristic of the existing venue and adjusting one or more acoustic parameters characterizing the model such that a predicted reverberation characteristic substantially matches the measured reverberation characteristic.
Claims18
An audio simulation system comprising:
- a model manager configured to enable a user to build a 3-dimensional model of a venue and place and aim one or more loudspeakers in the model;
- a user interface configured to associate a material with a surface in the 3-dimensional model and to receive at least one measured reverberation time value;
- an audio engine configured to adjust an absorption coefficient of the material such that a predicted reverberation time value matches the at least one measured RT value;
- and
- an audio player generating at least two acoustic signals simulating an audio program played over the one or more loudspeakers in the model, the simulated audio program based on the adjusted absorption coefficient.

An audio simulation system comprising:
- a user interface configured to receive at least one measured reverberation time of a venue;
- an audio engine configured to predict a reverberation time of the venue based on at least one absorption coefficient of a material associated with a surface of the venue;
- means for adjusting the at least one absorption coefficient such that the predicted reverberation time matches the at least one measured reverberation time;
- and
- an audio player generating at least two acoustic signals simulating an audio program played in the venue, the simulated audio program based on the at least one absorption coefficient.
