Abstract

[Feature] Approaches to directivity evaluation based on measurements made near the loudspeaker may make it possible to avoid the need for highly sophisticated anechoic chambers and exceptionally low noise floors. It seems that far field measurements may be able to be inferred from holographic or radiation mode analysis. While some doubt is cast on the commercial value of distortion reduction in loudspeakers using signal processing, the prediction and control of distortion is still an important factor in loudspeaker design, particularly for micro-loudspeakers. Loudspeaker driver modeling is becoming ever more advanced, enabling the detailed evaluation of nonlinear effects arising from things like flux modulation that could not easily be studied before now.
