Vibroacoustische

Vibroacoustische refers to vibroacoustic concepts, encompassing both the scientific study of how vibrations and sound interact and their practical applications. In engineering, vibroacoustics investigates how mechanical vibrations of structures generate acoustic waves in air and how acoustic fields feed back into vibrations. The field covers noise control, structural dynamics, modal analysis, vibration isolation, and the design of quiet, comfortable systems in automotive, aerospace, machinery, buildings, and consumer products. Research methods include experimental testing, finite element and boundary element analyses, impedance matching, and vibroacoustic testing.

In health and therapy, vibroacoustic therapy uses low‑frequency mechanical vibration together with acoustic stimulation delivered by transducers in chairs, beds, or mats. Proponents claim relaxation, reduced pain, improved sleep, and enhanced recovery. The idea is that tissues, joints, and the vestibular system respond to low-frequency stimuli, potentially influencing autonomic function and brain activity. Evidence for therapeutic benefits remains limited and mixed; robust clinical trials are scarce and results vary by condition and protocol. Safety generally appears favorable when devices are used as intended, but caution is advised for individuals with implanted devices, pregnancy, or certain neurological or vestibular disorders.

History and scope: The broader vibroacoustics field developed in the mid-to-late 20th century, with later growth in clinical therapies and consumer devices. It remains an interdisciplinary area spanning mechanical engineering, acoustics, physiology, and rehabilitation sciences. Related topics include acoustics, vibration therapy, noise control, and vibrometry.
