- Direct_Field_Acoustic_Testing abstract "Direct field acoustic testing, or DFAT, is a technique used for acoustic testing aerospace structures by subjecting them to sound waves created by an array of acoustic drivers. The method uses electro-dynamic acoustic speakers, arranged around the test article to provide a uniform, well-controlled, direct sound field at the surface of the unit under test. The system employs high capability acoustic drivers, powerful audio amplifiers, a narrow-band Multiple-Input-Multiple-Output (MIMO) controller and precision laboratory microphones to produce an acoustic environment that can simulate a helicopter, aircraft, jet engine or launch vehicle sound pressure field. A high level system is capable of Overall Sound Pressure Levels in the 125dB to 147dB for more than one minute over a frequency range from 25 Hz to 10 kHz.".
