Although the Mercedes S-Class (W221) has a very good noise isolation, it can be made even more efficient. The main structures that can be developed are:
- Rear wheel arches should be used for vibration-proofing material.
- Trunk trunk and space (need to use vibrating materials)
- The back wings-because the thickness of the metal is small, it is possible to use more light noise insulation.
- Place under the rear seat cushion (vagrant-pasting material), a partition between the boot and the passenger compartment (light noise insulation).
- The floor area (for high-quality noise insulation needs to be removed by air ducts of the ventilation system).
- The door is the easiest to use because it is of great importance to the doors. In addition, the structure of the structure is marked with a solid metal detail that significantly reduces the noise.
- Torpedo. This part of the car owners have the highest noise level claims, so special attention should be paid to the gluting of salon plastic.
