Hi all,

This a topic I concidered when I had my diesel before but never got around to it......so here it goes

Has anyone on here sucessfully soundproofed a felicia? I done 100 iles in it yesterday and the radio seems pointless as you can't here

it properly over the engine. I think the biggest gains for noise reduction would be from the engine bay and the bulk head.

Would love to hear peoples views on this or experience.

Thanks.

I'd be very interested in peoples views on this as my felly isn't the quietest either!

Have either of them got the insulation that attaches to the bonnet? Some of the petrol ones I had did and others didn't. The same with the insulation around the bulk head.

My 1.6 indeed has stuff on both sides of the bulkhead and under the bonnet - at 70mph on a motorway the loudest thing is the wind noise from the roof rails. As well as the clipped-on felt mat type insulation under my bonnet, I've also seen an older one in a scrapyard that had egg-box type foam glued into the gaps between the bonnet reinforcements (which looked to be original, rather than a bodge by an owner)

Same here; 1.6 & plenty of accoustic padding - no eggbox foam though.

ha, i've been trying to make mine louder

you need some of that thick foam to put round the footwells under the carpet and tha padding from under the bonnet, you could also fill up the doors etc with padding, but remember that it will add alot of weight to the car

Do you think that it would make a difference if it was added to the different areas! What type of material would be suitable?

There is some sound proofing on the bulk head, but i havnt seen the egg crate style under the bonnet and there is padding on the bonnet but it may be for heat insulation rather than sound.

the egg crate stuff (reticulated foam)is normally used for speaker cabinets or flight cases and it's not really suitable for cars tbh, when it gets waterlogged it stinks... you can buy rolls of that greeny looking stuff from most household furniture trimmer shops, it's quite expensive though

Is that for the inside or the outside " engine bay etc...."?

Aye, are you missing this?

(tis only ~£18 on fleabay)

^^ that reminds me, i've been meaning to remove mine for ages not, mine is soaked in oil that came out the dipstick tube when i... ahem... forgot to put it back in

That is on my car but I have seen people put more insulation direcilt onto the bonnet rather than just hanging it. "I wonder if I another one on there will it half the noise!!......lol"

With soundproofing, mass is everything. The heavy rubberised sheet which attaches to things is the way to go, and putting it on the bulkhead, etc., will do the trick, but you'll need a LOT of it (read £££), and I'd think you'd need to remove the dashboard to do a half-decent job, plus taking care of the sound coming out of the bonnet too.

Think this is going to be a bit of a job to do tbh and if you're after a comfortable and quiet motorway cruiser you bought the wrong car!

Having said that we have done trips to Germany in Nelly when I had her and it was very comfortable with minimal noise really but then we were only doing 60. I did do a short stint of 90 and the engine noise wasn't as bad as I thought tbh.

80 is pretty pleasent in the pug and engine noise seems to tail off at that speed (comes back if you go any faster). But also I think the pug is better insulated that my felly so you don't actually hear it.

Think it can have a lot to do with the engine revs and gearing. Just depends where the engine is happiest/quietest.

Might want to check everything is ok in your car before you head to sound proofing. If your wheel bearings are on their way it can make it sound like a noisy car engine (front) or exhaust blowing (rear bearings). I had no play in my rear wheel bearing and could only just hear it by rotating it quickly while jacked up, but at 70 mph it sounded horrendous! I've also heard the chain (in relevant models) can cause a huge noise issue. I've found that using premium petrol in my engine allows me to hit 70 with lower revs (about 100 - 200 less) and every little helps or an alternative to premium is to get normal petrol and put fuel injector cleaner in there.

Cheap tyres can also cause road noise I believe.

Don't know how much relevancy some of this has to diesels (I know there are equivalents to fuel injector cleaner etc) and I'm sure you've checked it all. Just thought I'd put it out there in case as my 1.3 MPi while it is noisey on the motor way turning the standard radio up a touch more than covers the noise of the engine at 70, its not noisey until about 85 - 90 ;-)

TBH I took the bonnet insulation off the Favorit and couldn't tell any difference (and the engine wasn't the quietest). So to do a good job of soundproofing I guess it would be a dash, trim, seats and carpet out job. I'd be inclined to just think of it as what it was, a car at the budget end of the market that isn't quite so refined as other cars out there, and put up with the sound. I guess having the 1.9d lump in there would be a little worse.

I have a stereo which auto-adjusts according to the volume of things in the car with a mic at the back, so if things noisy it's easier to hear, which I found worked quite well.
