MSI-DFAT® Provides Products and Services to Meet Your Specific Testing Needs
The MSI-DFAT test method uses a large number of speakers that surround the test article to create the acoustic test field. The speakers are controlled in zones and provide more flexibility than in a traditional reverberant test chamber. The DFAT test is most often controlled to simulate a diffuse field (as in a reverberant chamber), but it is also possible to target fields with other characteristics. This requires tight control of the microphones for good uniformity of the sound field and low coherence between them to avoid creating standing waves.
The convenience, low cost, and mobility of this method distinguish it from conventional testing and are the primary reasons for its growing popularity. The method is convenient because MSI brings all required sound systems, power generation and distribution, data acquisition and control equipment. All equipment is supplied for each test event. There is no large investment in a facility, equipment, or personnel required on the part of the customer. In addition, testing can be performed at a much lower cost per test compared to the installation, operation, and maintenance of a more standard high intensity reverberant acoustic chamber system. Finally, mobility allows this test method to be performed at almost any time and place in the normal test article integration and test flow. The test equipment is completely portable and no special facility or infrastructure is required. Learn more about DFAT®services here.
The MSI-DFAT® System uses a building block approach to satisfy our client’s specific needs. The system is designed, built, and operated by experienced and qualified audio engineers to ensure accuracy. MSI-DFAT® will perform the test on the spacecraft by a set of defined and documented procedures provided by MSI-DFAT® or to the client’s specifications. MSI-DFAT® systems are completely modular and mobile, allowing us to deliver to the client’s designated facility and complete a test in typically 3-4 days total. MSI-DFAT® can provide DFAT® Services and equipment through a rental or purchase agreements. The equipment is state-of-the-art, and our crews are committed to providing the highest level of service to exceed your expectations.
