Morris Minor Owners Club

Hi All,
As my car is in little bits and (maybe) going back together soon, my thoughts turned to noise reduction. Does anyone have any tried and tested methods to keep the noise outside the car?

I have been looking at the Woolieswebsite and they have lots of stuff, I'm just not sure what to get.

thanks!

B&Q felt type carpet underfelt. Easy to cut and shape, superb sound proofing.

Only soundproofing ive seen lately is in the wishing book - opps i mean the frost catalogue, as with most of it it's dear as can be.
For what its worth cant help lookng at the soundproofing stuff and it equalling moisture retention or cause of condensation and then moisture retention on the whole.
Theres heaps of sound deadening stuff on the undersides of most modern cars in the scrappy's nowadays. Could be worth trying modifying some of that in the name of cheapness

Cheapest, efficient method is something like this.

1. Ensure ALL grommets, door and window seals are in good order.

2. Insulate bulkhead, floor, underseat, and boot area with carpet underlay
You will need in the order of 6m x 2m. Pay particular attention to the bulkhead and boot area as these are the areas where most sound is transmitted.

Definately as many self adhesive sound proofing pads as you can afford, i think Frosts auto restoration do them or bound to be on e-bay somewhere.Especially on the insides on doors to make them shut with a thud and on the floorpan and bulkhead.If you use the felt stuff make sure you have a water tight body shell otherwise it soaks up the water nicely and then the rust starts.If you use the felt on inner wings its not a bad idea to staple the felt in heavy duty polythene and then spray glue in place. As suggested that green carpet underlay will be ok although it does tend to break up after a while but it will keep the sound down.Also the you can get an under bonnet sound deadening kit from the parts suppliers which might keep the tappet/timing chain noise down and one final thought don't fit a stainless steel exhaust ,what a racket !!

Don't buy Frosts, its far too expensive, a 54" x1m sheet of self adhesive can be had for a couple of Frosts small ones. If doing the job properly you will need two sheets. Drop me a PM for details.

I spent about £200 on sound proofing(from Woolies),and put it everyware,and it did very little to stop the engine drone and wind noise in my traveller.

What i should have done was to spent my money on a louder sound system

Metrication is progressing nicely I see! ;)

Aye!! their figures not mine

When fitting under carpet does it also go over prop shaft tunnel and up behind pedals?

Yes I got several layers on floor sections, and two layers under pedals and on the bulkhead. It does need a dry car though with no water leaks, as it's uber absorbent. Plus side of things is it's very light weight, and really cheap.

MT - do they sell it by the roll - or will they cut it to a length?

Sold by the roll for just under £20 and you get (from memory) 10 meters long by 2 meters wide.

Thanks MT - don't need that much - actually for my TR7 which is in the midst of new carpet fitting if the $£%^&£ rain/snow ever goes off! But I'm sure there will be other uses for it.

Carpet fitting can be a real pain on the Minor when underfelt is applied first. Especially along the transmition tunnel. Remember also to leave cut sections so you can get at the gearbox and brake reservoir fillers.

Peetee, you say to insulate the bulkhead firewall with carpet underlay. I have a sound deadening mat that I got from a local car shop. It is about 3/4" thick, and looks like it is made from recycled wool. WOuld this be suitable for the bulkhead, or does it need to be something fireproof?????

Wool is pretty much 'fireproof'. You will also need to put the soundproofing on the underside of the bonnet.

If it's the stuff that is tightly packed fibres and is natural colour on one side and black on the other then you can use it as described but it's not the best available. the problem with any of the fibre based mats is the fibres can get everywhere when you start cutting it. Even when you have applied it to the bulkhead for example the unprotected surface and complexity of cut sections still leaves exposed edges where fibres can break off and float around when your driving your car. This is why I removed the original sound proofing on my first Mog - it was very unpleasant to be in it with the roof down. You can carefully spray the edges with matt black paint to stabilise them but once you start to have to do that sort of thing using the rubber crumb backed stuff starts to become a better albeit more expensive option.

Its natural colour on both sides. It was very cheap, so probably isn't good quality, but has still made a noticeable difference. I might try and stuff some in the boot behind the back seats as well.

What kind of material do you use for the bonnet? I've got some self adhesive eDead material, but it is silver and very expensive, so I don't really want to use it for the bonnet. ESM do a bonnet insulation kit, but it is £40!
