• Description:
• FE 02.0492/2025/IRB "Psychoacoustic noise assessment: Expansion of assessment procedures and development of innovative noise reduction strategies in road traffic" Traffic noise is one of the three greatest environmental threats to health - after air pollution and climate-induced influences. The Protection from noise is and remains an important task in road traffic and at the same time is associated with ever greater challenges. In the area of ​​federal highways, too, with the available measures it is becoming increasingly more demanding to comply with the applicable limit and trigger values, which increases the need in new noise reduction strategies and innovative approaches to noise protection. To date, the assessment of road traffic noise has mainly been based on averaged level variables such as the energy-equivalent continuous sound level. Such level variables are a good measure of the objective noise pollution, However, they do not adequately reflect the actual, subjective noise nuisance. The subjective perception of sound events is significantly influenced by other acoustic and non-acoustic factors. The research field of psychoacoustics deals with precisely these relationships between physical sound characteristics and subjective perception and offers a promising approach to complement existing evaluation metrics. The aim of this research project is to expand the assessment of road traffic noise to include psychoacoustic parameters. It should be worked out how psychoacoustic parameters can be specifically integrated into the noise assessment or the quantification of noise reduction measures in order to map the perceptual effects. This is intended to better capture the variance in the perceived annoyance of road traffic noise and a more differentiated quantification of noise reduction measures will be made possible - especially in the area of ​​subthreshold levels, which has so far only been possible with conventional evaluation variables imperfect...
