Installation & review of sound deadening sheets on my S-Cross

Thanks to the sheets, the doors have now got a satisfactory 'thud'.

BHPian DieselAnna recently shared this with other enthusiasts.

Glad that things are running fine with the car. Last week sat in a cousin's Baleno and noticed the cabin is quieter than normal. On asking he said, that he has done sound deadening with sheets on all doors and boot lids. I got curious and enquired around and got a contact, which I already had but didn't know that they do sound deadening.

Approached this store called Tufkote Dinitrol in Goregaon Mumbai. The owner, Ryan, met me and explained how sound deadening works and what's the logic. S-Cross 1.3 always had poor NVH at highway speeds and road noise was also intrusive in the cabin.

The sheet is used for sound deadening.

These sheets are self-adhesive and are pasted in the doors after removing the door panels. Boot lid too is done. Application photos I don't have, unfortunately. But the sheet is cut into smaller sizes and stuck to the door panel.

I was also suggested to do wheel well coating with water-based compound, which will take care of road noise creeping inside. The Cowl area was also opened and painted with this liquid.

My review after driving the car for 100kms after this activity:

1. Damping has shown great results in keeping engine noise out. It's minimal. I can rev till higher rpm without the strain noise reaching me. I used to avoid this earlier because it wasn't enjoyable earlier. Below 2k rpm, I can hear faint engine noise, which was not the case earlier. This is achieved by coating the cowl area.
2. Doors have a very noticeable 'Thud' because of the sheets. I love this.
3. Road noise has been reduced on gravelly roads. Went up to 100 km/h on the highway with minimal noise. It's not like you are completely cocooned.

This is not similar to soundproofing. Those sheets are different and are applied on the complete inner side of the door. Damping sheets are applied in smaller pieces on areas where the vibrations are higher.

Since these panels were opened, I went ahead and did antirust coating at drain spots. This was not done because the car has any corrosion. It's precautionary only.
