Acoustics simulation

Minimize noise and optimize sound quality

Are your customers expecting quieter products? Are competitors gaining ground by using sound quality as a differentiator? Will tighter noise regulations impact your product sales? Would you like to decrease the time spent on predicting sound fields or shave off weeks on complex jobs like engine run-ups?

Acoustic Simulation

Acoustics analysis can help you conquer these challenges. Simcenter offers interior and exterior acoustic analysis within an integrated solution that helps you make informed decisions during the early design stages so you can optimize your product’s acoustic performance. A unified and scalable modeling environment combined with efficient solvers and easy-to-interpret visualization capabilities enable you to quickly gain insight into the acoustic performance of your product.

Acoustics simulation helps you minimize noise or optimize sound quality in designs. Read more about our acoustics simulation capabilities:

Acoustics modeling

Shorten model preparation time and enhance productivity with custom modeling tools specifically aimed at speeding interior and exterior acoustics simulation processes. Using unique capabilities such as surface wrapping for fast fluid domain creation and the ability to quickly create a convex mesh, you can conquer complex geometry and start your acoustics analysis sooner.

Aero-acoustics

Automatically generate composite manufacturing data — such as flat patterns and data to drive automated cutting machines, laser projection systems, fiber placement machines, and tape laying machines — and share it downstream and across the enterprise.

Boundary element acoustics

Often used for exterior acoustics problems, the boundary element method (BEM) is ideal for problems involving very complex geometry that may be a challenge to model for the FEM method. The BEM method helps simplify exterior acoustics simulation since only the outer surface mesh of the geometry is needed. This simplifies both the modeling process and reduces the degrees of freedom in the simulation model which will result in easier analysis.

Finite element acoustics

The finite element method (FEM) for acoustics analysis is ideal for simulating interior acoustics problems. In addition to FEM being the more efficient method in terms of solution speed, FEM acoustics lets you perform coupled vibro-acoustics analyses that take structural modes and sound proofing materials into consideration. FEM acoustics can be used to solve exterior acoustics problems as well, which is often used for noise analysis of air induction systems in powertrain.

Ray acoustics

The human hearing frequency extends up to about 18 kHz. Doing acoustic simulations up to this high frequency range is not always possible with standard finite element method (FEM) and boundary element method (BEM) technologies. Ray Acoustics allows you to competently and accurately perform acoustic analysis for these high frequencies and allows you to efficiently and accurately perform various audio and in-vehicle acoustic comfort simulations, covering the entire hearing frequency range.
