Acoustic testing

Design, verify and validate the sound of your product.

Design products with compelling acoustics

Acoustic quality and acoustic design are key aspects of product performance. Sounds play a critical role in conveying the right message about a product’s features and functionality and reinforcing brand image attributes. At the same time, regulations and competitive pressure are forcing manufacturers to limit noise levels and meet stringent noise-making or noise-limiting standards. Engineers need productive tools to design, refine and validate prototypes throughout the development cycle.

Covering the broadest range of industry applications and engineering tasks while conforming to the latest international standards, our acoustic testing solutions adjust to your project’s requirements. Design innovative products with a compelling acoustic signature, relying on the expertise nested in our intuitive solutions.

Pass-by noise testing and engineering

Pass-by noise testing as certification remains a very important test. It can keep automotive manufacturers from selling their new models on the market.

Acoustic testing capabilities

Acoustic troubleshooting

Our Simcenter Sound Camera hardware will enhance your product acoustic design. It minimizes the time spent in tracking down sources that contribute to unwanted noise.

Its robust, modular design supports many sound source localization applications over a wide frequency range, both in the far and near acoustic field. The dedicated software shows results immediately after starting up. It delivers clear, graphical results that are easy to interpret and share. For increased engineering insight, you can also combine the Simcenter Sound Camera hardware with the Simcenter Testlab software.

Active sound design

Engine downsizing, cylinder deactivation and powertrain electrification change a vehicle’s sound signature. To maintain or redefine the brand sound, active sound design enhances interior sound and adds exterior sounds for the acoustic vehicle alerting system (AVAS). Our dedicated automotive solution includes several sound design methods and real-time synthesis based on various engine parameters, such as speed, throttle position and torque. You can validate the synthesis in the office, on a driving simulator or in the vehicle using a dedicated hardware.

Pass-by noise engineering

Lowering pass-by noise level limits, updated certification standards, and the introduction of new technologies force NVH teams to adopt innovative and efficient pass-by noise engineering methods. Rely on our indoor and outdoor pass-by noise certification solutions to speed up testing against a wide range of institutional regulations and directives. Our solutions include test-based engineering methods to design vehicle sounds and predict pass-by noise levels.

Sound intensity testing

Simplify the processes of intensity-based sound power testing while ensuring compliance with ISO measurement standards for both scanning and point-by-point methods. Our solution integrates a fully automated procedure with robotized movements of the probe. It delivers adequate results for certification processes and additionally permits sound localization on a 3D geometry as well as the ranking of sound sources.
