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.
