Abstract
A fiber body includes a collection of fibers containing thermoplastic resin as the main component and an energy consuming component, such as a piezoelectric material for converting and consuming external mechanical energy of sound and vibration. The energy is converted into electrical energy, which in turn, is converted and consumed into and as heat by means of the electrical resistance of the resin.
