NVH Simulation
NVH simulation enables managers and customers alike to ‘drive’ rival vehicles and previous models in highly realistic scenarios so engineers can quantify their opinions.

Initial subjective and objective benchmarking, vehicle-level and system/component-level target setting, NVH troubleshooting and development to achieve programme targets.
HBK solutions for End-of-Line (EoL) provide full functional and acoustical behavior analyses of each eDrive unit directly in the production. Automatic evaluation of path/fail criteria enables maximum quality and high productivity. In case of failure, digital twin model can identify the root cause.
Identifying the sources of the vibroacoustic emissions that we both hear and feel is essential to creating comfortable vehicles.
While noise and vibration can be readily measured and quantified, harshness is a subjective quality, therefore the human factor is critically important for the target-setting process and performance evaluation. The NVH process is very much a mixture of subjective and objective evaluations with NVH Simulation playing an ever more important role.
NVH testing plays an important role throughout the vehicle lifecycle, from initial vehicle concept to final production and in-service operation. These include:
HBK offers a complete range of NVH measurement and analysis solutions, including high-quality, precision measurement hardware and powerful software.
To enable the identification of production issues, a portable analysis system has been developed to complement the subjective impression of the audit driver by automatically producing objective data that can be used to diagnose and solve problems.
Microphone arrays help engineers develop sound quality on vehicles, giving fast and effective noise source identification. Now, advanced new techniques improve the insights possible.
Road traffic noise is one of the most widespread environmental noise problems globally. To help reduce noise in our environment, government agencies set pass-by noise emission limits for each category of ground vehicle. HBK indoor pass-by testing helps vehicle OEMs comply with new noise limits.
Located in Canton, Michigan, Material Sciences Corporation (MSC) is a materials supplier and engineering services provider, primarily working on innovative solutions for lightweight, acoustics, and coated-metals solutions. They offer products and services for a wide range of industries and markets.
The automotive engineering landscape has evolved over the last five years for the OEM and tier suppliers. For OEMs, new ownership models, rapidly advancing technical innovations, and growing competition across the mobility space have forced the industry to adapt.
