Why use wave6 for modeling noise and vibration?
Its no longer adequate to analyse the mechanical, aerodynamic and thermal performance of your product without also considering noise and vibration performance. By integrating wave6 into your design process you can ensure noise and vibration performance is built into your product at the design stage, and therefore reduce the risk of discovering expensive noise and vibration problems late in the design cycle when physical prototypes become available. Whether you’re a vibro-acoustic specialist looking for the next generation of analysis methods or a CFD user that needs to predict the noise arising from unsteady flow, wave6 has the methods you need.
What’s your background?
What analysis methods does wave6 include?
wave6 provides methods for efficiently and accurately simulating noise and vibration across the entire audible frequency range. We’ve written all of these methods from the ground up. This means that instead of having a collection of disparate solvers that are individually licensed, the methods in wave6 are truly integrated into a single common engine with a single common environment and controlled by a single license. This enables us to combine methods in the same model and efficiently analyze noise and vibration problems in ways that are simply not possible in other software packages.
What are some of the industries and applications where wave6 is used?
Noise and vibration analysis is becoming increasingly important in virtually every industry. The need to reduce noise and vibration can arise because of government legislation, new lightweight constructions, use of lower cost materials, detectability, fatigue failure or increased competitive pressure. Regardless of the application you’ll need a way to characterize the complex sources acting on your system (including complex unsteady flow sources) and a way to diagnose and rank the various transmission paths that transmit noise through your system. You’ll also need accurate models of the frequency dependent dissipation and isolation that arises from poroelastic noise control treatments and structural isolators.
