The Inventors of Direct Field Acoustic Testing (DFAT)

25+ Years in the Space Industry

275+ Combined Years of Acoustic Qualification Testing

MODULAR CONFIGURATION

Adaptable to any size test article. The MP150 offers flexible height configurations, surpassing 40 feet, to optimize your test.

HIGH POWER

Push the limits of low-frequency acoustic tests with confidence. MP-21 subwoofers are designed for high power levels - ideal for demanding applications.

MSI-DFAT® provides Direct Field Acoustic Testing (DFAT®) as-a-service for spacecraft. DFAT® is used for acoustic qualification testing of aerospace structures and components.

 

The DFAT® test setup involves electro-dynamic loudspeakers, arranged uniformly around the test article, to generate a diffuse and well-controlled direct sound field at the surface of the unit under test (UUT).

 

DFAT® has replaced traditional, expensive reverberant chamber acoustic facility tests (RAFT or RFAT) with an economical and superior alternative for the space industry.
