This sub-theme deals with structural vibrations and the associated sound radiation. Our research addresses, in particular, Near-field Acoustic Holography (NAH) and, more specifically, improving the accuracy and resolution of NAH and extending the formulation to localising sources in the presence of reflecting surfaces, temperature gradients or transient events. Benchmark applications are found in automotive (tyre-road noise), and in vibration detection for high-precision motion stages. The focus is on the one hand on numerical/computational tools for acoustic models, and on the other hand on the experimental validation of those tools, for example in the anechoic laboratory. People active in this area: Prof.dr.ir. I. Lopez Arteaga & Prof.dr. H. Nijmeijer
