Sound field reconstruction: a comparison between different technologies
Sound field reconstruction: a comparison between different technologies
This presentation is an introduction to two methods for the reconstruction of a sound field:
high-order Ambisonics and the Least Square Method. The theoretical background to these
two approaches is presented and some sound field reconstruction animations, obtained
with numerical simulations, are shown in order to illustrate the differences in the
performance of the two methods. Finally, an important result is presented: the
mathematical proof that high-order Ambisonics and Least Squares Methods are formally
equivalent under certain regularity conditions of transducer arrangements. This result is
confirmed by numerical simulations
