Direct Field Acoustic Noise (DFAN) Testing

DFAN, or Direct Field Acoustic Noise testing, is a method for acoustically testing spacecraft or other items without requiring a special, dedicated test facility with a reverberant room. In a DFAN test, a set of speakers are used to surround the test object to recreate an acoustic field. This video gives a complete overview of DFAN testing and how it compares to RFAN (Reverberant Field Acoustic Noise) tests. Also includes a demonstration of Simcenter Testlab software for performing these tests.
