The invention relates to a plate resonator for sound absorption, comprising: - a thin front plate with high elasticity and low internal friction, e.g. made of metal, - a rear plate also with high elasticity, but with high internal friction, - a full surface fixed connection between the front plate and the rear plate acting as an adhesive bond (e.g. double-sided adhesive tape), - a surround closed on all sides by the rear plate and not impairing the side sound inlet into the rear plate.
