Abstract: Physical measurements of loudspeaker performance are becoming recognized increasingly as a reliable guide for the evaluation of loudspeaker excellence. Facilities for the calibration of loudspeakers and microphones are described. The measurement techniques are illustrated with data describing a recent model loudspeaker showing the principal performance criteria; namely, frequency response, angular distribution, and distortion. Suggestions are given for a uniform presentation of performance data and specifications.
