A new AES Standards project, AES-X193, "Sound source modeling - Array and cluster polar radiation measurements" has been initiated.
The standard aims to "specify how the angular measurements of polar radiation data for arrays or cluster arrangements of loudspeakers shall be made and documented. This acquired data is suitable for application in room acoustic, electro-acoustic, and sound system predictions, and loudspeaker data sheets."
Multiple loudspeakers may be used from the same or different manufacturers to create an array or cluster of loudspeakers. There are additional requirements necessary for these measurements beyond those spelled out in the existing AES56 standard on polar radiation measurements. It is important that these requirements be standardized in order to enable the use of this data in room acoustic, electro-acoustic, and sound system predictions.
Development of this standard has been assigned to the AES standards working group SC-04-01 on Acoustics and Sound Source Modeling. More information can be found at:
