Behind the scenes

Find out how Acoustic Garage works.

Acoustic Garage is based on a set of complex simulation tools that Autoneum has developed in-house. The software then analyzes the acoustic performance of the components and the vehicle configured by you in real time.

CAD

Thickness Distribution


Using the part’s computer-aided design (CAD) data, Autoneum’s VisualSISAB software generates a 2D thickness distribution from the 3D part geometry.


Transfer Matrix Method


A Transfer Matrix Method (TMM) calculation is then applied for each layer of material.


Acoustic performance results


The part’s acoustic performance (transmission loss and absorption) is deduced by combining each layer’s respective performance.



Now, it is up to you to choose the best compromise of acoustic performance versus design constraints (i.e. weight, coverage area, pass-throughs).

CAD Model

Topological Model


Starting from the vehicle’s computer-aided design (CAD) data, a topological model of the vehicle is created and imported into Autoneum’s REVAMP software. This model is the framework of the Statistical Energy Analysis (SEA) calculation. REVAMP uses this methodology.

The SEA model is a three-dimensional arrangement of entities (panels and cavities) that represent the physical subsystems of the vehicle with associated acoustical properties. These are necessary to evaluate the energy exchange throughout the vehicle.


Apply external loads


For the SEA model to be fully representative of an actual vehicle, external noise impinging on the vehicle under normal driving conditions must be applied.


Vehicle sensitivity


Additionally, areas where expected leakages may occur (grommets and door seals), are also implemented into the model.


VisualSISAB part performance


By combining the resulting parts performance (calculated with VisualSISAB) with the SEA model, Autoneum can predict the expected Sound Pressure Level (SPL) at various locations inside the vehicle.
