Title

Influence of the Moisture Content of Thermoplastics on their Vibroacoustic Behavior

Abstract
The vibroacoustic behavior of plastic components can vary significantly depending on climatic boundary conditions. For example, an electrical device with a plastic housing can sound very different in summer than in winter. Acoustic evaluations of plastic components are therefore mostly carried out under defined climatic boundary conditions. In addition to temperature, the moisture content is often an important vibroacoustic influencing parameter. This contribution deals with the influence of the moisture content of different thermoplastics on their vibroacoustic behavior with regard to vibration damping.
