HIGH INTENSITY AND UNDERWATER ACOUSTICS
A Full Suite of Proven Acoustic Testing Equipment Products and Services for RATF, PWT, or DFAT Testing
Whether testing a spacecraft in a reverberant acoustic test facility (RATF) or a component in a progressive wave tube (PWT), the principles 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.

|
High intensity acoustic test facilities represent a significant investment, and SignalSound services and support can help extend that investment. Trained technicians can repair noise sources, amplifiers, and cooling units, and existing test facilities can be upgraded with the latest acoustic controllers, dynamic signal measurement systems, noise sources, amplifiers, cooling units, and horns.

High and Low Frequency Acoustic Power Generators
Electropneumatic Transducers for Generating High Intensity Acoustic Noise for Aerospace Environmental Qualification Testing
Data Physics offers an Acoustic Power Generator for high frequency testing applications. This acoustic power generator, or APG, is often called an electropneumatic transducer or EPT.
The SignalForce LE-APG-10K is a high frequency noise generator that produces 10 kW of acoustic power with a gas flow of 1500 scfm. The spectrum from the APG-10K can be shaped and controlled in 1/3 octave bands up to the

LE-APG-10K High Frequency Acoustic Power Generator
1.25 kHz band, and acoustic power is produced above 1.25 kHz through the useful distortion of the power in the lower-frequency bands. The APG-10K is fully compatible with the older Ling Electronics EPT-200 design.
For low frequency acoustic testing products, please visit Team Corporation (our NVT Group partner company) to learn about their MK VI (150,000 W) and MK VII (200,000 W) Acoustic Noise Generators.

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 different 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.
