BURLINGTON, Mass., Sept. 12, 2013 (GLOBE NEWSWIRE) -- Exa® Corporation (Nasdaq:EXA), a global innovator of fluids simulation solutions for product engineering, announced the release of the newest version of its noise analysis simulation software solution, PowerACOUSTICS® 3.0. This latest release allows users to predict noise transmission into the cabin from the underbody flow, which is an important source of wind noise in the low-mid frequency range. Users can now also add in any other noise contributions such as from road, tire, or engine sources, giving PowerACOUSTICS the ability to synthesize total noise in the interior. This release also features new acoustic visualization capabilities that provide enhanced visibility and understanding of the acoustic field, enabling even better insight to the sources of aerodynamically-induced noise.

With recent advances in the reduction of engine and tire noise, and with ever more vehicle electrification, wind noise is an increasing component of the total noise in the interior. Exa provides a complete, integrated, solution for prediction of noise levels and identification and reduction of wind noise sources. PowerFLOW's inherently transient fluid simulation provides accurate prediction of the turbulent and acoustic wind noise sources. PowerACOUSTICS predicts transmission of those sources to the cabin interior or propagation to the far field, and the ability to simulate the effects of different sound-reduction packages, such as use of laminated glass or damping materials.
"Quiet vehicles are what consumers demand and manufacturers strive for," remarked Robert Powell
, Director of Structural Acoustics for Exa and chairperson of the SAE 2013 Noise & Vibration Conference
. "Quietness equates to quality for the consumer. I'm thrilled that we can now accurately synthesize the total noise experienced by the occupants. This latest PowerACOUSTICS release further extends Exa's leadership in aeroacoustic simulation."
