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.
