Control of Velocity for Sound Field Reproduction
The conventional approach of using the method of matching the acoustic pressure on a bounding surface for the reproduction of a sound field in the enclosed volume has been shown to suffer from technical limitations when the loudspeakers used for reproduction are irregularly distributed. The difficulties in sound field reproduction with an irregular (spatially non-uniform) loudspeaker arrangement have been resolved by changing the component controlled from acoustic pressure to acoustic particle velocity. The velocity controlled sound field shows better reproduction of the time averaged intensity flow in the reproduced field and this can be shown to be related to the main cues for sound localization regardless of loudspeaker arrangement. This is accomplished by matching radial particle velocity components in the target and reproduced fields on the surface of the control volume whose size is made frequency dependent. The performance of velocity matching method is discussed in this paper and compared with the conventional pressure matching method through computer simulations based on a loudspeaker layout. Furthermore, the simulated results were verified experimentally.
