The Analysis, Interaction, and Measurement of Loudspeaker Far-Field Polar Patterns

We present a mathematical framework for the analysis, interaction, and measurement of loudspeaker far-field polar patterns using spherically weighted complex acoustic point sources. We show it is not necessary to know the "acoustic center'' in order to measure an accurate far-field polar pattern. We discuss a mathematical transform that makes this clear, and we show experimental evidence from careful measurements in an anechoic chamber.
