"I can't hear a word your saying"

[kevbutty]

I've been on a bit of a mission over the last couple of weeks to make my defender quieter   I've removed the transmission tunnel and floor sections and refitted them with sealant. I've cut up a large rubber boot mat and glued it around the seatbox, which looks quite smart  
Also I have sealed all the holes in the battery box and put some new seals on the access hatches under the seats.
It is alot better than it was but I still feel it could be quieter. Has anyone got any simple cheap mods to reduce road noise etc.
The noise I seem to be hearing is the engine  
Its a 1994 90 200 tdi HT by the way.

Now about a sound proofing kit..?

My 90 had a sound deadening kit on it when I got it.  The underbonnet stuff fell off the first time I went off road, but it had been on since 1996, previous owner only used it on road and occasional run across a field for work.  It still has soundproofing under the rubber mats on the floor and all over the seat box and it's the quietest defender I've been in.  Worries me though cos when the bearings go in the gearbox I won't hear them

[diesel_boy]

get rid of it and but a v8  much quiter  unlike mine sounds grate from the exsaust  tube

Must admit some soundproofing is on the list for my defender, was wondering about this stuff :-

Anyone got any experience with it ???

(Unlikely to be cheap though!!

Noisekiller stuff is good from what I know of them, have spoken to them on several occasions...

why they changed their name is anyones guess.

as daft as this may sound, the "main" sources of noise transmission are the bulkhead itself (a large vertical sheet of metal ) and the roof...

make sure the roof is both lined, and that the lining will reduce the vibration too, since that's a huge rattle panel.

The disco has something like the weight of a passenger in sound dampening glued to various parts of the engine bay,  which is around the only reason it's quieter.

An under bonnet kit would likely help a lot...

Thanks datalas

When time permits I will try and quieten down the beast, the only underbonnet kit existing at the moment is a bit of mud, don't suppose that has much effect. (What is the dB rating for mud anyway).

Like your other suggestion though, I just have to decide which of my passengers to use as a soundproofing kit, yougest son comes to mind.  Well, probably not, he's 6'-4" and 18 stone - (could be overkill), besides he is my best assistant where heavy lifting is called for.
Seriously though, there is a headlining in the defender it's some sort of felt thingie..., thought some of the noisekiller liquid might help.  Anyone out there used it??

Cheers

V8_redline7500 & i found a cheap and chearful way of soundproofing the V8 90 racer......................use a pair of 5 quid peltor ear defenders........great cure,lol

[Xtremeteam]

although the use of ear defenders can be slightly worrying to other road users,maybe the fitment of an intercom may help,it did for me,ive just got to remember to turn (V8_redline_4500) down when sittingon the startline  

[kevbutty]

Thanks for the advice  =D> chaps.

Might get some of that noisekiller liquid stuff.

Off to Wales tomorrow for a spot of lanning over the Breacon beacons  \/  and we're watching a winch challenge at the Seven sisters on Sunday.

Don't think the 2 hour trip up the M4 will be much fun though  
I mean't to get some ear plugs but didn't get round to it.

[Xtremeteam]

well,if it becomes to much for you just turn the radio up,im not looking forward to doing the mudmaster next weekend as its 2 days in a soft top 90 with SATS & a blowin exhaust,anyone able to lend me a pair of practice headsets for a terraphone intercom???

Very much like the the economic soundproofing solution, unfortunately came upon a small problem when suggesting it to co-pilot,

It went something like - " After I've paid £**~~.&& for my hair straightening I aint wearing them".

Looks like I'm back to sticking on lots of felt then...

Oh! well,
still thought it was a d**m fine idea though,

This chap's had some really bad feedback recently. It may be as he says, but could be worth holding off a while.

[Xtremeteam]

Back again,just got home from the mudmaster & am now deaf, #-o  .did not that bad (4th) would have been 2nd had i engaged brain aswel as low box & difflock,picked my car back up  which is fitted with a straight through exhuast & induction kit & its SO much quieter than the 90.
