摘要

A semimanufacture intended to be mounted on a vibrating wall or a vibrating panel for actively damping the vibrations in the wall or the panel with frequencies which are at least partly audible, wherein the semimanufacture is provided with a plate wherein the plate is integrated with: at least one vibration source for generating vibrations which, in use, damp the vibrations of the wall or the panel, at least one vibration sensor for detecting the vibrations in the wall or in the panel and wiring for connecting the vibration source and/or the vibration sensor with a control unit for processing signals coming from the at least one vibration sensor and for controlling the at least one vibration source.
