I read some comments that Aerosol sound deadener (in the 400g cans) for the wheel arches is just too thin to work. Despite this, I bought 3 cans of 3M Sound Deadener from SupaCheap Auto and used them up on my 4 wheel arches. The result is pretty good,, but I am wondering whether there are still improvements to be gained by slapping on a whole lot more!
I'll try to give an indication as to how tyre-to-road sound has changed.
When driving on new high quality roads, I'm guessing there is at least a 5 dB drop in volume, and the noise which is coming through is much lower frequency. The effect is very significant.
When driving on roads with ridges every say 10 metres, the thud when hitting each ridge is very repressed and is much shorter. It is still noticeable.
When hitting breaks in the asphalt, the thud is still very noticeable but radically less than it was.
Could I expect further improvements with more sound deadening, or is this as much wheel arch improvement as I can reasonably expect?
