Abstract

The paper describes how with one identical method the surface of a vibrating structure as well as the emitted acoustic sound field in air as well as the internal mechanical stress σ(t) in the vibrating structure can be investigated and visualized. This unique capability opens new possibilities for improving and optimizing the development of effective long-term stable sound transducers with optimized emission characteristics. Furthermore, the method can be used for investigating the internal stress of models of dynamically stressed mechanical structures. The simultaneous visualization of vibrating surfaces, internal stress σ(t) and emitted sound contributes to a better understanding of the behavior of complex dynamically excited structures.
