New standards in vehicle acoustics

The BaLSaM project is reaching exciting milestones in vehicle acoustics research. Our latest advances open up exciting insights into the world of traffic noise and thus the acoustic analysis of vehicles.

A significant step in our project is the development of an innovative adapter design for mounting microphones in the immediate vicinity of the tyre. This extension of the microphone positions enables more precise and extensive measurements of tyre noise on different vehicles and has provided valuable information.

Another important focus of our research is the investigation of electric vehicles. In addition to tyre noise measurements, we have concentrated on the "Acoustic Vehicle Alerting System" (AVAS). The AVAS is an acoustic warning system that alerts pedestrians and other road users to the presence of the vehicle at low speeds. Our measurements of the AVAS have enabled us to analyse and evaluate the acoustic properties of this system in different situations and on different vehicles.

At the same time, our project partner, the IHTA (Institute for High Frequency Technology and Acoustics), has analysed the acoustic phenomenon of diffraction using measurement technology. This data is crucial to better understand the propagation of sound in different environments and to develop simulation models.

The BaLSaM project has already made significant progress in vehicle acoustics research. Our advanced measurement methods and collaboration with experts in the field are deepening our understanding of vehicle noise generation. We look forward to further developments and how they will influence the future of transport planning with regard to vehicle noise.
