AES-1id-2012-r2017: AES Information Document for Acoustics - Plane wave tubes - Design and practice

Printing Date: 2017-12-31

Publication History: Pub. 1991, Revised 2012; Reaffirmed 2017

Abstract: The AES2-2012 standard "AES standard for acoustics - Methods of measuring and specifying the performance of loudspeakers for professional applications - Drive units", calls for the use of plane-wave tube measurement of horn drivers. Because many variations and results are possible, depending on the details of construction of plane-wave tubes, this document discusses those variations for the purpose of encouraging further experimentation. This 2012 edition is a revision of AES 1id-1991. Additional uses of a plane-wave tube are listed. Further tests were performed to compare a distant microphone location with a close location to test the hypothesis that non-plane-wave radiation would be more accurately measured. A termination method is described. A modern method of calibration is referenced and summarized. (22 pages)
