COMET enables you to predict the way sound radiates inside and outside of a product, simultaneously or separately
COMET enables you to predict the way sound radiates inside and outside of a product, simultaneously or separately. By giving you a better understanding of the noise your products will make, COMET helps you refine your design - before investing in costly physical prototypes. COMET offers two key advantages over competing solutions: it's easier to use and it's supported by the engineers at AAC - known worldwide for acoustic expertise.
- The Power to Solve Your Noise Problems
- The Interface to Make Your Job Easier
- The Expert Guidance in the Best Way to Solve Your Noise Problem
- The Versatility to Move Across Computer Platforms
No other acoustic solution has the capabilities to solve your noise problems faster than COMET. The software is used for determining:
- The acoustic normal modes of an interior space or cavity
- The noise at discrete frequencies internally and/or externally of an object due to structural vibrations and pressure pulse excitations
- The noise resulting from structural vibrations, while simultaneously calculating the response of the structure from acoustic excitations - a truly coupled solution
- Acoustic responses in fluid, solid, and elastic porous (foam) media
- Optimal designs of structural components for sound reduction
- Sensitivity analysis determines the relative affect on the acoustic response due to the surface vibrations of a component at discrete frequencies.
- Panel contribution analysis predicts which components or areas have the greatest effect on noise levels.
- Mean flow analysis considers the fluid velocity effects on acoustic response.
- Near field acoustic holography analysis predicts the surface velocity distribution on a structural when the acoustic pressure field is already known.
- Nonlinear matrix interpolation for multi-frequency analysis drastically reduces computer run times.
- Reverberant field analysis predicts the structural response of components immersed in an environment of random acoustic vibrations.
- Discontinuous impedance modeling allows for thin panels to have materials with different absorption characteristics on either side.
- Multi-media acoustics analysis predicts the acoustic response throughout domains with varying acoustic properties.
- Test correlation allow results from the lab to be combined with COMET results to obtain a complete and accurate representation of the sound field.
- Sound field visualization of the following is possible using COMET/Vision as a post-processor
- SAFE (Structural Acoustic Foam Engineering) lets you analyze the process of structural acoustic energy transmission through foam. Until SAFE, no solution could model the physics of this entire process.
- SAOpt (Structural Acoustic Optimization) lets you optimize the structure of a design and its acoustics - at the same time. No more tedious working iterating between structural and acoustic systems.
