Good morning folks, this has likely been done before but as i am new, i can't find it. If there's an existing thread out there, perhaps someone could point me towards it...
I recently upgraded my speakers across the front of the car. While i am pleased with the improved sound, above 40-50mph(80kph) i still feel like i'm having to crank up my music to hear it correctly. I feel i now need it uncomfortably loud when i am travelling on Motorways or i'm just missing frequencies. So i set off trying to learn about noise in the cabin.
Using a free sound meter app(Not ideal i know), I have the following,
53db @ Idle
67db @ 30mph
70db @ 40mph
73db @ 50mph
77db @ 60mph
80db @ 70mph
These were all taken on a fairly rough piece of Dual Carriageway but it's fairly typical of what i'm driving on i think. The car feels to me unnecessarily loud, but maybe i'm too deeply involved that i want to convince myself that that's my issue. Either way if i could get these numbers down a bit i'd be delighted!
So far I have, stripped the car from the back seats rearward and found the dreaded rear pressure relief vents leaking (L/H & R/H) and the VW boot handle drain pipe leak. 2 days to fix them!! I have put down Dynamat Xtreme wherever i have found thin sheet metal that flexes easily. i'd say i've covered 60% of available metal back there. I will now move forward where i would expect to make the most gains however, perhaps Dynamat xtreme will only deaden vibration induced noise and what i really need is to put in Dynaliner(or similar) on top of whatever i feel is weak in relation to allowing sound to pass through.
Assuming i'm on the right track, for anyone that's done this,
Where did you find the worst areas in the Golf Vii?
Is there any sound insulation on the floor pans other than the carpets?
What are the firewalls like? Do you improve them from inside or outside?
Is a hoodliner worth it?
I'd appreciate any info you folks have on this. I'm in my late 30's and this is only my 2nd car, I have had this for 4 years and can't see me letting go of it for another 4 years at least, so it is worth putting time into it. I'm also an Engineer by trade so i have plenty of ability, my Engineering background is not Automotive so i would enjoy learning from anyone elses experience in trying to quieten their Golf.
Cheers!
