Acoustic Testing 

Wyle has a long history of significant contributions to the technologies associated with high-intensity acoustic testing systems. In the 1960s, Wyle developed the first high-power, linearly controllable electro-pneumatic noise source, the WAS 3000.

Wyle developed reverberant and progressive wave testing facilities for its own use and, in 1967, began to design and construct similar facilities for an impressive list of major aerospace contractors. These customers include Perkin Elmer, RCA Astro-Electronics, GE Space Systems, Martin Marietta, McDonnell Douglas, TRW, Boeing, and Lockheed Martin.

Wyle offers specialized expertise in support of turnkey facility development in which Wyle is responsible for all aspects of facility design and development, as well as the resultant performance of the facility.

Wyle also has developed a series of standard subsystems and components including:

Acoustic Modulator - The WAS (Wyle Acoustic Source) -3000, is an electro-pneumatic WAS 3000noise source rated at 30 kW output, with either sine or random wave input, over a frequency range of 25 to 10,000 Hz. The WAS-3000 is primarily used in acoustic test chambers where it can generate overall sound pressure levels up to 165 dB. Higher sound pressure levels can be attained in very small volume enclosures, and/or multiple modulators.   The Wyle Acoustic Source (WAS) 5000 acoustic transducer is an electro-pneumatic noise source rated at 10 kW output over a frequency range of 25 to 5,000 Hz. Primarily used in acoustic test chambers, the WAS provides the full range of noise evaluation of large components for spacecraft, missile and advanced aircraft systems.

The WAS 5000 can reproduce exact sine wave, random noise and sine-random combinations. In reverberent chambers, the units can generate overall sound pressure levels up to 160 dB.

High Intensity Acoustic Horns - Wyle horns can be provided for cut-off frequencies from 10 to 200 Hz and are fabricated from fiberglass reinforced polyester resin. The horns can accept either the WAS-3000 or WAS-5000 modulators.

High Intensity Noise Doors - Wyle also provides doors suitable for acoustic environments up to 165 dB are available with sound transmission losses as high as 70 dB at 500 Hz. Personnel doors suitable for acoustic environments are manually operated, while larger doors (up to 500 ton or 453 tonne) are provided with powered operators.
