Abstract
Engineering-grade product noise emission testing programs are qualified, and correction factors are applied to test results, based on “known” sound power levels of a reference sound source; i.e., a sound source that has been tested and qualified in accordance with ANSI S12.5/ISO 6926. The accuracy and uncertainty of ANSI S12.5/ISO 6926 test results are then transferred to the engineering-grade testing program and are thus of crucial importance. ETS-Lindgren recently commissioned the new Acoustic Research Laboratory at headquarters in Cedar Park, TX, and is developing an ANSI S12.5/ISO 6926 reference sound source testing program. This work included evaluation of factors contributing to accuracy and uncertainty. The application of microphone frequency response corrections (obtained from outside calibration laboratory) is discussed and data are presented. In addition, the use of windscreen insertion-loss corrections is discussed and data are presented.
