Sound deadening materials

[quote=Thor;5874]What Philip says is all true.

A company called Noisekiller Acoustics makes a range of materials. They have a dynamat-type stick-on material and also a heavy-ish foam backed rubber material which can be cut to shape and laid under carpets, etc. this material is flexible engought to shape around trans tunnels, etc.


I have taken the plunge and bought some Dynomat Extreme which I have used to cover everywhere aft of the front of the rear seat. A slight nuisance is that the tunnel carpet is glued down. It has made an appreciable difference, principally getting rid of high frequency noise. This could of course be entirely imaginary. I have bodged the doors for now as I have lost the allen key I need to take the inners off so I only covered what I could reach through the speaker aperture. I have ordered the engine bay version of Dynomat, but I think I will have some fun trying to apply it to the engine bay, but I will see how I go.

I looked at noisekiller. It is cheaper than Dynomat, I might order some for the doors to compare it.

The main thing I want to eliminate is the sewing machine engine noise. I will report back.
