The way loudspeakers interact with their acoustical environment is highly dependent on the directivity and has a direct effect on the listening experience. From the point of view of a speaker designer, there are endless choices to make a loudspeaker very directive or omnidirectional, starting from cone materials, system design, to active control using digital signal processing.
However, doing accurate acoustical measurement in 3D is still a challenge. To learn more about directivity measurements see E-Learning Training 8, which illustrates both traditional far field measurements as well as state of the art holographic measurement techniques.
