Analysis of 2D sound reproduction with fixed-directivity loudspeakers

Poletti, Mark; Betlehem, Terence; Abhayapala, Thushara


The implementation of 3D sound reproduction is well founded theoretically, but the requirements for the number of loudspeakers and array geometry make it impractical using conventional technology. In practice, a 2D array of loudspeakers is commonly used which restricts the reproduction of sources to those in the horizontal plane and requires a restricted form for the free-field loudspeaker driving signals based on the sectorial spherical harmonics. However, reflections can impair reproduction...[Show more]
