High order Finite Elements for mid-frequency vibro-acoustics

The quantification of vibroacoustic properties in multi-floor timber buildings is currently still based on measurements and computational models are rarely used in practice. One reason surely is a lack of validated and robust numeric schemes for vibro-acoustic simulations covering mid-range frequencies which can be integrated smoothly into the planning process of multi-floor timber buildings. To this end, we lay out a pipeline for the prediction of mid-frequency vibro-acoustic behavior of laminated timber constructions by modal analysis using three-dimensional high-order finite elements. The integration into the planning process is achieved by deriving the computational model from IFC-based building information models.     «
