Analysis of 2D sound reproduction with fixed-directivity loudspeakers

Poletti, Mark; Betlehem, Terence; Abhayapala, Thushara

Description

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]
