Motor vehicle door with an outer door skin and an inner door skin, between which a wet space is formed, and with a door interior trim, between which and the inner door skin or a carrier plate (2) of a door module a dry space is formed, in which a noise-generating unit (7) and a loudspeaker (8) are arranged. The loudspeaker (8) is connected to a wall of a substantially closed resonance chamber, in which at least the noise-generating part of the noise-generating unit (7) and means for acoustically and/or thermally influencing the noise-generating unit (7) are arranged, and which is sealed in such a manner that airborne sound can only escape via the membrane of the loudspeaker (8).
