Findings and discussions from our presentations at the AAC

The BaLSaM project has reached another milestone, and we would like to report on our sometimes very diverse content at this year's Aachen Acoustic Colloquium (AAC). We presented a total of three talks in a dedicated BaLSaM session, highlighting different aspects of our research and providing an insight into the diversity of our work.

Carolin Schliephake from ika and Chalotorn Möhlmann from IHTA spoke about the "Holistic Approach for Aurally Accurate Road Traffic Noise Reduction by Adaption of Traffic Routes and Infrastructure Planning." This presentation was primarily dedicated to tyre-road contact as a noise source and investigations to verify the sound propagation simulation.

Moritz Lippold from RHA then presented his lecture on "Urban Noise Protection Measures from the Perspective of Urban Designers - Case Study of the "Gräselberg - Auf den Eichen" Master Plan". In his lecture, he presented the results of the designed residential neighbourhood, which was created with a special focus on acoustic challenges and concepts. As an urban planner, he brought a breath of fresh air and a new perspective to the AAC.

Thiago Lobato from HEAD rounded off the trio of presentations and spoke about "Optimising the Estimation of Vehicle Sound Radiation Characteristics by Combining Numerical Models and Microphone Array Measurements".
The focus here was on a new approach to determining the radiation characteristics of tyre-road noise through a suitable combination of simulation and measurement data.

Participation on site not only enabled us to present our research results, but also to engage in in-depth technical dialogue.In addition to the normal project meetings, there were valuable discussions and personal conversations that further deepened the collaboration within the consortium. We are delighted with the response and interest in our work and look forward to incorporating the findings into the next phase of our project.
