The invention relates to a composite soundproofing system for the delimiting surfaces of a room, consisting of at least one cladding layer (V), a damping layer (D) and a sound insulation layer (S). By selecting suitable combinations of the flexion loss factor, the monoaxial extension loss factor and the dynamic rigidity of the sound insulation layer (S), high-quality footfall soundproofing can be achieved in addition to a significant improvement in the emission behaviour of the cladding layer (V) in terms of sound emission in the room. Said system permits thin layer thicknesses of the complete system, even with surprisingly high dynamic rigidities. |
