  "textContent": "The device has a hollow transmission body connected to a sound source. The transmission body radiates modulated sound in air to a target space(s), has an oscillation body and is sealed gas tight so the input and output gas pressures act on the opposite sides of the oscillation body, which is stimulated to oscillate and produce modulated sound in air that is radiated and is a stiff and/or rigid body held parallel to the sound propagation direction. The device has a hollow transmission body (13) connected to a sound source for coupling out sound in air. The transmission body radiates modulated sound in air to at least one target space (16), has an oscillation body (19) and is sealed gas tight so that the input and output gas pressures act on the opposite sides of the oscillation body, which is stimulated to oscillate and produce modulated sound in air that is radiated. The oscillation body is a stiff and/or rigid body held (20) parallel to the sound propagation direction (22,23) of the incoming and/or outgoing sound in air.",
