Directivity Measurement of In-Wall Loudspeakers
March 16, 2022 by Christian Bellmann, Ruben Hauschild, and Mattia Cobianchi

Directivity Measurement of In-Wall Loudspeakers

In this article, the authors share their research on new requirements for the measurement of in-wall installation speakers. The directional characteristics are an especially important factor, because the direction in which a loudspeaker emits sound highly affects the interaction with the listening room and the listening experience. The authors' research addressed the requirement using holographic directivity to address the way the directional characteristics interact with the listening room. This article was originally published in audioXpress, December 2021.
