A sound insulation element for the wall of a vehicle body between the passenger compartment and the engine compartment has a front side facing the passenger compartment formed by the outer side of A plastic carrier layer, and a rear side which rests against the front wall formed by the outer side of a sound-absorbing layer. At least one holding-down projection projects from the plastic carrier layer at and/or offset from the edge of the hole of the carrier layer on the inner side of the plastic carrier layer facing away from the outer side of the plastic carrier layer facing the sound-absorbing layer, which is embedded in the sound-absorbing material of the sound-absorbing layer and whose free ends facing away from the plastic carrier layer are substantially aligned with the outer side of the sound-absorbing layer facing away from the plastic carrier layer.
