Abstract
The use of the sound intensity technique to determine the sound power output of a source has become very popular over the years. An American National Standards Institute committee, ANSI S12-21, is currently engaged in developing a suitable standard for making sound power measurements using the sound intensity technique. The draft version of the proposed standard permits the use of both fixed point measurements and also continous hand scanning on the enclosed surface. To check the validity of the sound power measurements and to help make suitable changes to the measurement procedure, many optional data quality indicators are also included in the draft. Recently, the working group ANSI S12-21 organized a round robin test on a standard reference sound power source. Various organizations across the United States participated in the round robin test. This paper summarizes and discusses the sound power measurement results obtained on the reference sound source.
