High Intensity ACOUSTIC TEST CAPABILITIES
A Full Suite of Proven Acoustic Test Products and Services for Reverberant Chambers or Progressive Wave Tubes
Whether testing a spacecraft in a reverberant acoustic test facility (RATF) or a component in a progressive wave tube (PWT), the principals of operation are the same. Both types of facilities require a compressed flow of air or nitrogen, noise sources, test chambers, and acoustic control systems. Data Physics can offer both expertise and equipment for new facility development as well as repair and service of existing facilities.
For new facility development, Data Physics can act as a primary subcontractor on any RATF or PWT project.
Capabilities include concept and preliminary design, supply of specialty equipment, design and construction meetings, startup activities, acceptance testing, training, and documentation.

Acoustic Control for Reverberant Acoustic Test Facilities (RATF), and Progressive Wave Tubes (PWT)
The SignalSound Random Acoustic Controller is designed to be used with a Reverberant Acoustic Test Facility (RATF) or a Progressive Wave Tube (PWT) to simulate high-intensity acoustic noise similar to that experienced during a rocket launch or high-speed flight.
The Random Acoustic Controller runs on the Data Physics Abacus hardware. Abacus is ideal for acoustic testing with high dynamic range and excellent channel-to-channel phase matching. Up to 32 input channels can be used for microphone measurements and up to 8 output channels can be used to drive separate acoustic noise sources in di¬fferent frequency bands. Random acoustic control supports 1/1 octave, 1/3 octave, and narrowband control. A local throughput disk in the ABACUS hardware enables continuous throughput to disk of time history data for post processing.
Safety of the test article is at the forefront of the controller design, and a range of safety checks provides protection for the test article.
The Random Acoustic Control software provides extensive display and analysis capability during a test. The test operator may view time and frequency domain data (narrowband or nth octave) from all active channels during the test. Averaged control signals can be overlaid with reference and tolerance profiles.
