This project brings together a multidisciplinary team of researchers with advanced expertise in wood materials, sound field analysis, building acoustics, modeling, and perception evaluation. Perception can no longer be condensed into a single number (such as impact sound level) based on outdated methods and limited structural diversity. Thanks to novel recording technologies, their unique combination, and mathematical modeling, coupled with advanced methods for analyzing and interpreting human perception, a comprehensive understanding of the acoustic and vibrational interaction between buildings and occupants can be achieved.

The project results provide the basis for the development of highly efficient floating floors and impact sound insulation layers with high acceptable point load and low dynamic stiffness using renewable materials. Furthermore, the unique combination of sound and vibration in capturing and reproducing stimuli leads to more authentic artificial environments for participants in laboratory settings. This novel approach in perception studies results in a realistic environment for auditory and vibration tests, allowing for the identification of new metrics to assess the success of the development.

Advanced measurement and simulation methods will be developed to support an effective future research and development process for these structures by generating virtual stimuli to quantify the performance of these new constructions based on their realistic impact on annoyance caused by footstep noise for building occupants.
