Abstract

Many methods and systems have been investigated for reproducing a physical sound ?elds. Local Sound Field Synthesis was proposed as a way to achieve this at high frequencies, involving the formation of virtual secondary sources that surround the listener’s head. In sound ?eld synthesis, the shape and discretization of a loudspeaker distribution affect both the accuracy of the sound ?eld reproduction and the reproducible frequency range. This study clari?es these dependences by means of simulations. The results indicate that the arrangement of the loudspeaker array affects the signal-to-noise ratio most signi?cantly when the array is discretized with low density.
