| Résumé |
Commonly used types of loudspeaker systems have directional patterns that bear
no relationship to those of the sound sources which they purport to simulate.
The purpose of this project is to derive some parameters linked to the radiation
and relevant to our perception.
To address this problem, a series of three separate experiments have been
conducted:
(1) collect data on sound power spectra and directional characteristics of
musical instruments to be simulated.
(2) build of a multiple drivers reproduction system with signal processing
control.
(3) investigate the physical and psychophysical properties of this sound
source when the directional programming is varied. The influence of the
coupling of the sound source and the room on the perception of the
simulated sound sources is also examined.
