Looking for recommendations of where to buy soundproofing and also where to fit it. 3500rpm at 70mph appeals to no man after three hours at the wheel of a Fabia with knackered seats.

 

Muchos Gracias folks.

Bump out of interest

I've been looking at rolls of stuff off ebay to do my two.

I think the biggest gains are to be had from doing the boot area as there's not much sound deadening there. 

Aye I had thought about the boot area. Under the bonnet would be my other choice too.

I fitted the under-bonnet sound deadening pad from a vRS. Makes a suprising difference. The orange plastic clip that holds the bonnet stay is different for the models with the pad and has to be changed.

 

As DieselMonte says, the vast majority of other noise comes from the back. I sound insulated under my back seat, the boot floor and inside the hollow rear quarters. Made a big difference to road noise.

Thanks, Lee. Going to have the car in tons of bits over the Summer anyway for a deep clean since it's absolutely filthy inside, so I'll start sticking insulation in those bits.

A few useful part numbers...

Thanks once again. For anyone else: can't get the bonnet stay or the acoustic pad off eBay at the moment, but the clips can be had in packs of ten using @TMB's link.

Snap, posted the same link as TMB lol.

I used this https://www.ebay.co.uk/itm/255234238733?hash=item3b6d25690d:g:X8UAAOSwrpRdlG2C on the underside of the plastic engine cover on my MK1 Octy diesel and with the bonnet open it reduced the noise by 6db according to the app on my phone 

For rattle, drumming, vibration types of noise I've found self-adhesive stick on van type sound deadening pads to be very good, they're the only sort of sound or any insulation on my car other than the world's cheapest "carpet" set, no underfelt.  A lot less effort to fit as you can fit bits one at a time and you can add more if required later, they can be cut into smaller shapes or strips if required.  Mine are just stuck on painted panels on the bonnet, in the boot, engine bay, footwells - but not on the doors where I intended to start as I couldn't be arsed to remove the door cards and it's mattered so far.

 

I can't find the ones I got, 10 panels and I still have a few left, but these I give as only an example of what I mean, these are smaller pads but less cutting then. -  https://www.ebay.co.uk/itm/300894542405

One other thing to look at is what about your tyres?

 

Different tyres can have a huge amount of difference between how noisy they are.

Yep, I went from Toldeos on the front and some no-name ditchfinders on the rear which made an awful din. In comparison my Matador tyres are whisper quiet. 

 

The biggest issue I've got is engine noise on long journeys.

For engine noise timely servicing and perhaps oil choice a bit, induction noise (air filter and housing), exhaust noise, noise from the engine ancillaries and a/c and perhaps others stuff in the engine bay, then as you're considering sound deadening or insulation to and/or from the area.

 

I find my wife's 2015 Fabia engine bay noisy from inside the car, perhaps that's partially why VW cars are heavy all the sound insulation, less insulation on the non-VW badge cars to keep price and value differentials.

 

Perhaps you are more used to quieter cars, a free phone App measured my car at 93db at a steady 30mph with the roof down, it'd be more with the roof up.  Never tried on my wife's Fabia, the blower motor is noise if above 1 and the a/c adds its own noises, engine bay noises vary all the time, then there some sort of noises from the front wheel area, no noticeable induction or exhaust noise though, well not over the rest anyway.

Always serviced and looked after. The exhaust is quite throaty for a "standard"-spec replacement that was fitted before I bought the car.

The other two cars in the "fleet" are two fairly clattery Dacias. This car is quieter (less wind noise but more engine noise), but it could be quieter. As outlined above, cutting engine noise is my main priority. I can live with the creaking and clunking over bumps (I will fix that someday) but the engine noise is my biggest peeve with this car because of the short gearing in 5th (3000rpm @ 60mph).

Though the engine isn't designed as a barnstormer nothing wrong with 20mph/1,000rpm, puts 60mph at your max torque.  Couple of decades back my wife had a three-pot with 16mph/1,000rpm in 5th (top) gear and she'd have it in 5th at 35mph, though it was a marvellous bulletproof Japanese engine in a smaller capacity engine and smaller lighter car.

 

Timely changes of things like plugs and other items can help a bit rather than trying for world-record mileage use because they still work and haven't totally fallen apart but you're not going to beat the engine design and engineering quality.

 

Also bear in mind your car and engine are 16 years old, you've probably forgotten how noisy cars used to be and you didn't see so many smaller family cars at 16 years old still running back when your car was new let alone before it.

 

As said by others tyres make a big difference to noise and comfort and any suspension, steering, hubs, wheels or component support wear will add to the cacophony.

 

Perhaps your standards and expectation of noise and comfort are too high, or your servicing and maintenance standards not as high as you think - or you just have above average hearing sensitivity, but not for the whole range if you listen to cassettes. 😄

  

My 1.4 mpi does about 3,200 rpm at 70 mph and is surprisingly quiet at that speed. You can barely hear the engine, the rest is road noise. I guess with yours being a 3 pot that it's inherently a bit noisier. The Estelle 105S I used to have would deafen you at that speed (when it was able to get there)

All I'm saying is on road trips the people in the back of my mk2 have a hard time hearing the people in front. 

I wouldn't be expecting it to turn into a Rolls Royce with a few rolls of sound deadener  but keeping things a bit quieter couldn't hurt.

Same issue with my Mk1. I don't expect sheer luxury and I'm a bit corned beef (deaf) anyway so it must be bad if I can hear things.
