SignalSound Random Acoustic Controller

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.
