hi guys my google-fu isn't on good form today. i'm after some heavy blankets with sound absorbing property.

it's actually to put around the wheel well of my station wagon ... but i guess these things are usually found under home construction material.

was thinking of some old wooly carpets lol

tyre roar is unbearable, i can't hear myself speak when driving over chipseal

There are various sound deadening products. Dynamat is the one that's been around forever, there are various cheaper products too that I'm sure would work fine.

If you put 'sound deadening' into supercheap autos website it produces some results.

Looks like its all special order though.

I have put tgese guys all over the wagon. The music is awesome and the door closes like a merc. But it is actually a dampener. It still transmits sound. Need sound absorber over the wheel wells.

Note I haven't tested it yet but I'm pretty sure that's the theory. Mass vs energy etc

Have you considered better tyres?

might try continental next time. got Michelin Pilot Sport 4. Prior to that Bridgestone Potenza RE050A. 45 profile.

my van is quiter. we can have a conversation between driver and right at the back. it's got Contis.

still won't stop me shoving blankets over the wheel well.

i think a lot of the noise is actually through the door seal.

Having gone through this before, change your car. What ever you do will only make a minimal improvement. Good sound isolation is engineered into the car at the design stage and it is very difficult to achieve later.

completely agree. i've got nothing better to do esp with the lockdown coming up.

it's kind of an experiment to prove just that.

so far with all the dampeners I can hear sound coming through the door seals :)

i read the germans have super good door seals, even double seals

Double seals certainly work on dishwashers.

As it's rear doors you could seal the doors up with tape to see if that makes a difference.

A big part of the noise will be the vibration coming back up through the car. You won't stop that with blankets. Invest in better tyres or change cars. Some cars are just bad for road noise, pre 2004 Mazda's come to mind.

What sort of vehicle? I have Conti Sport Contact 5's on one of my cars currently and will probably swap to Pilot Sport 4's next time. The Continentals came on the car, the noise level is OK but anecdotally the Pilot Sport 4's are a better tyre. Can't speak for the road noise. Wagons are often noisier as they don't have the sound deadening created by having a barrier between the cabin and the rear of the vehicle like a sedan does.

Nothing wrong with the Pilot Sport 4's as a tyre which is what the OP has already.

it's the car. as i said my van which is much older is way quieter. the material i bought was for $120 for the whole car, it's now completely damped.

no chance of seeking chipseal as we are in lockdown. (it's very very quiet on tarseal before my exercise anyway.)

but i'm sure little will change, i just did this for fun.

then realised the car's covering trim around the rear wheel arch has huge gaps. perfect for some heavy blankets. but no idea where to get them.
