NVH measuring system
For All Measurement Tasks In The Field Of NVH, Squeak & Rattle And Sound Quality Testing
The MB Dynamic BSR SUITE is a comprehensive solution for all measurement tasks related to NVH, Squeak & Rattle, and Sound Quality testing. Its extensive analysis and evaluation capabilities also make it suitable for assessing functional and operating noise, the effects of vibration on humans, as well as the acoustic and haptic feedback of controls and actuators.
With predefined test configurations for common tasks like multi-channel road load data acquisition, drive-file generation, and objective Squeak & Rattle and Sound Quality testing, the suite ensures quick and straightforward operation. Users can perform objective evaluations of various acoustic or haptic quality criteria using signal statistics and user-defined thresholds or reference curves.
The BSR Editor offers comprehensive tools for editing, filtering, analysing, and converting recorded time signal data. It allows for easy and effective comparison and combination of multiple recordings by enabling parallel editing of multiple records. Cutting, copying, and pasting relevant time signal sections from different recordings into a new file is intuitive and straightforward. Integrated knowledge and procedures for transferring vibration conditions from the road to the lab enhance the simulation quality and correlation to road testing.
