Soundproof Help

[pannawonica]

Her indoors has been giving me a little grief over my 110 Puma, noise and the front seats . Used to run Disco's TD5/V8's, Deafender shall we say is a little way off their level of refinement. Anyhow Scheel-Mann seats on the way and Dynamat Extreme has arrived. However I am still looking for a decoupling layer to go on top of the Dynamat. Has anyone had experience of Pyrotek products, Soundune caught my eye but ther are several others. Please advise.

Whatever you use must be water proof...

I can only comment on the products I have used.
Dynamat Superlight with Dynaline over the top.
Don’t expect it to be as quiet as a Merc etc or you’ll be disappointed.
Was it worth the effort, I think so. But lower your expectations. It’s not a magical cure.

4 Db would be good, 6 Db on the wish list.

I got 3dB drop (at 80-100kph) in the 300Tdi 110SW using the Exmoor / Wright of Road - Acoustic moulded mat, which has just recently become avialable for the PUMA.

It looks good, fits well, and importantly shields the seat box from all that transmission heat in the summer.

Next I'm going to pull the mat off from under the bonnet, insulate the bonnet against the aluminium, then refit the mat.

After that I might look at something on the engine bay side of the fire wall.

I'm using my TD5 D2a as a bench mark and making comparative measurements with each step.

At idle in the engine bay (standing in front of the car with meter over the radiator), the TD5 is 1dB quieter than the Tdi, at 80 vs 81dB.

Shut the bonnet and the noise from the D2 drops to 69dB vs 71dB from the 110.

Most of the noise seems to be coming from the front, now that the Acoustic Mat is in, so insulating the bonnet first would seem to give the biggest (quietest) bang for buck.

Michael, has the price dropped at all.

IIRC the last time I enquired (beginning of the year) it was still upwards of $600 for the Wright mat ?

No, I have been trying to get a reply from Wright for awhile, the last time they replied the dollar bought 33p so I couldn't do it. More recently, they seem to be selling through Exmoor. While the price has almost doubled, so had the Australia Dollar.

I bought it from Brookwells, minus VAT, plus FED-EX it was over $900 to my front door. The PUMA one costs 50 pounds more, so expect about $1,000 landed.

I figured it was the easiest way to do the job, I had some tax return money, and figured if I didn't spend it now, a hearing aid was going to cost me more in the future.
