Presentations at Inter-Noise

On Tuesday and Thursday, IHTA and HEAD acoustics gave presentations at Inter-Noise.

IHTA's presentation titled "Validation measurement of vehicle pass-by models for dynamic urban environments" dealt with a method for the validation of traffic noise simulations through measurements in a hemi-anechoic chamber in order to provide a better understanding of the effects of urban structures. This method includes challenges and approaches for the precise detection and auralisation of traffic noise in urban contexts with a special focus on interactions between sound, buildings, and walls.

HEAD's presentation entitled "Physiological responses to soundscape recordings in a laboratory experiment" dealt with the soundscape approach, a holistic method for evaluating acoustic environments. This approach can be extended by physiological measurements in order to include the physical response of the listener in the evaluation. In order to be able to design VR experiments with physiological measurements in the future, this study initially used purely acoustic stimuli to investigate which deviations in different traffic scenarios actually cause differences in physical reactions.

Status meeting at HEAD acoustics

Earlier this week the BaLSaM status meeting was held at HEAD acoustics in Herzogenrath! As usual, all project partners updated each other on the current status. The consortium also listened to presentations by HEAD and IHTA, which they will present at Inter-Noise next week.

Mid-Term Event

On May 21st, our Mid-Term Event was held to update the public on the current status of each of the project partners. Through numerous discussions, experiences were exchanged and content was debated. Participants were also able to immerse themselves in the VR demonstration "IHTApark" by project partner IHTA, where the environment around the IHTA was auralised and visualised on the basis of physical descriptions.

Consortium meeting 04/2024

Another consortium meeting took place at ika yesterday! It was the last status meeting before the mid-term event in May and was primarily used to exchange information between the partners involved and to discuss current progress and challenges. At the mid-term event, progress to date will be presented and the exchange of experiences and joint work on future challenges will be encouraged. Are you interested in taking part in the mid-term event? Then register now!

DAGA 2024

The project partners ika and IHTA presented current project results at the DAGA.
Carolin Schliephake (ika) gave a presentation on the "Development of a deterministic modelling approach for the prediction of tyre-road noise". The prediction model was presented in 4 stages: In addition to the investigations at component level and those at overall vehicle level, the transferability between these levels of complexity and the model validation were discussed.Chalotorn Möhlmann (IHTA) gave a presentation on "Comparing Simulated and Measured Urban Traffic Noise". The study presented examined techniques for the auralisation of urban traffic noise. The auralisation techniques were validated by a comparative analysis of simulated and measured data in built environments. This was done using the statistical pass-by measurement method, which refines the auralisation models and helps to better understand the challenges of noise pollution. At the DAGA, numerous consortium partners could be met in addition to the technical presentations, so that the exchange within the consortium was strengthened once again. However, numerous interesting discussions were also held with research institutions and companies beyond the consortium, which emphasised the importance of a broad network and open exchange for the success of research through these diverse interactions.
