HEAD acoustics Insights:
Model-Based Development in Practice
The world of NVH development is changing. Advanced technologies, approaches and product solutions emerge, and face higher quality standards and customer requirements at shorter product development cycles.
This presentation intends to provide an overview of model-based NVH product development today. From global target setting to target breakdown on component level, quality assurance in acoustic End-Of-Line testing, and early prediction of final customer acceptance – the linkage of model-based approaches gains significant relevance throughout the entire development process.
Providing both expertise in engineering and advanced product solutions, HEAD acoustics approaches to model-based development in practice will be presented.
SOUND QUALITY METRICS:
Analysis, Evaluation and Classification of Acoustic Patterns in Benchmarking, Product Development and End-of-Line Scenarios
So-called Sound Quality Metrics are used in various applications today, modelling the perceived Sound Quality of a product by instrumental analysis methods.
Being able to predict the acoustic quality of a final product, a certain prototype modification, or a simulated design change, Sound Quality Metrics are considered a relevant tool in acoustic development. When embedded in End-of-Line scenarios, SQ Metrics succeed in ensuring the acoustic quality of a product. Needless to say, any benchmarking campaign with focus on human perception gains validity when being supported by such instrumental analysis methods.
This online seminar presents the approach of developing Sound Quality Metrics by using Machine Learning techniques.
CREATING A DIGITAL TWIN:
Application of TPA in the Context of Driving Simulator Technology
Efficient product development today is increasingly utilizing the so-called digital twin.
In this free online seminar, the HEAD acoustics engineering team in Germany will present how transfer path analysis and an interactive NVH simulator are applied for evaluating NVH quality in a virtual prototype. After introducing the basic concept, an automotive case study is shown including the following applications:
- Interactive NVH driving simulation based on TPA model
- Integration of active sound enhancement in the virtual protoype
- Virtual exchange of component based on test bench measurements
- Driving simulator with powertrain in the loop
CLOSING THE GAP BETWEEN TEST AND SIMULATION:
Accelerating Development by Using Hybrid Approaches
The investigation of NVH phenomena in modern products requires an integrated approach combining advanced experimental and numerical methods. The vibroacoustic transmission path from excitation sources through structural dynamics to perceived sound radiation is a fundamental aspect of NVH analysis.
Beginning with practical examples and extending to industry-relevant cases like e-bikes, the approach highlights the influence of structural properties, resonance phenomena, and modal analysis techniques. Measurement optimization, model updating, and the use of hybrid models form the core of effective workflows.
Within this online seminar, insights into NVH analysis workflows and modeling strategies to enhance noise and vibration are discussed.
HEAD acoustics Insights:
Holistic Investigation of Acoustic Zones in the Electric Vehicle
Successful design of vehicle interior acoustics requires a
consideration of acoustic quality of all noise components involved at
all passenger positions, as well as communication effort between
passengers in the vehicle and telecommunication to exterior receivers. A holistic investigation of all relevant acoustic characteristics of
the vehicle is mandatory to achieve this goal. In addition to
powertrain, wind and road noise contributions ("NVH behavior"), this
also includes analysis of all aspects of “communication effort”, e.g.
listening effort in the interior, ease of hands-free communication and
use of voice control.
Especially in electric vehicles, the properties of introduced
synthetic sounds ("active sound design") need to be addressed more
comprehensively to avoid unwanted side effects on communication effort.
Within this online seminar, current progress in the field of holistic
analysis of acoustic zones in the vehicle interior is presented and an
exemplary case study of a high-performance electric vehicle is
discussed.
HEAD acoustics Insights:
Optimization and Validation of Active Sound Design Concepts for Electric Vehicles
The implementation of active sound design concepts in a target vehicle requires careful tuning of all synthetic sound elements with respect to existent vehicle interior noise, current driving conditions and general driving styles. Besides the creative aspects in sound design, this tuning process is highly time-consuming. It must be ensured that load feedback, speed feedback and general interactivity with the synthetic sound meet the driver's expectations and match the intended emotional expressions of the sound concept.
Testing the tuning parameters in real vehicles requires access to the vehicle prototype and all involved system components, which is often not granted in early development stages. A key approach to overcome this difficulty is the application of acoustic driving simulator technology, directly linked to the main tuning parameters. Combining this methodology with an efficient procedure for perceptive assessment of the sound design model, an interactive approach to active sound design is established.
Within this online seminar, current progress in the field of efficient tuning of active sound design models is discussed.
