A sound generator () mounts on a vehicle to manipulate vehicle noise originating from a vehicle operated by an internal combustion engine. The sound generator () includes a casing (), a loudspeaker (), and at least one pressure compensation valve (). The loudspeaker () and the casing () together thereby enclose a volume (). Further, the pressure compensation valve () couples the volume () enclosed by the loudspeaker () and the casing to an outside of the casing (). The pressure compensation valve () thereby extends through a plane in which the loudspeaker () is located. A system () for manipulating sound waves propagating through exhaust systems of vehicles driven by an internal combustion engine uses the above sound generator ().
