It varies from 30hz all the way up to 550hz. I got to get a video recording, for you to see. Link to comment Share on other sites More sharing options...

The loudest ones probably the one that's reverberating in your cabin and annoying you.Is it like a bassy "booming" constant kind of sound when you're going up hills or at a certain rpm?

Basically how "loud" specific frequency ranges are in the overall sound profile. 1 Link to comment Share on other sites More sharing options...

I will have to get a video recording up on imgur. Link to comment Share on other sites More sharing options...

I put a lil dynamat in both front doors and that was a huge difference on highway cruising, did you deck out your front doors? you put invos on ay? kinda sounds like tyre noise ish. also isnt there some thing where the noise comes in through where the manual gearstick is, and you can insulate it? the recording device seems to be above this is all.

We struggle a bit to have a quiet conversation at 100km/h. That video was at 100km/h. yeah I got the invo's on the rears only. The mobile phone recording this is above the dash near the A pillar.
