Default Road noise

Anyone tried sound deadining material to cancel out some of the road noise?

I am not to worried about the extra weight like some of the pro racers here and would like to regain some of my hearing again (the roads in portland suck, lots of rocks in the asphalt to help move all the water that gets on them).

I also noticed that I loose alot of my bass tones on my sound system from this road noise. The treble sounds fine.

I would think that some of the road noise are out of phase with the bass, is the road noise the thumping like when you go over bumps or is it just a constant bombardment of clicking noises?

I put dynomatt in all the doors but ut really didn't help the road noise. It was meant for the audio. But I don't think the db level in the car is bad at all. It's actually pretty good if your previous car was a Mustang GT. That is loud! STi is quiet as hell in comparison.

You just aren't hardcore enough!

Seriously, the STi is designed for speed and performance. Almost of necessity to reach its price point, niceties like quiet interior too, are laid aside.

Crank up that motor and party on!

If you want it quiet, remove the entire interior, dynomatt the doors, the floor, and the firewall. That should add a ****load of weight but give you a quieter ride.

Default clicking

It's mostly a series of fast vibrations like going over a cheese grater. That's why I cant' understand why the bass is going away. But if you slow or stop the car the bass comes booming back proportional to the speed you are slowing too.

It's not horrible but I figure if I can quiet it down I wouldn't worry about a little extra weight. How much weight are we talking about?

yes... the roads in OREGON are noisy. just finished a 600 mile to portland and man... my ears were dying. i had to crank the stereo just a wee bit more.

and yes, sound deadening wil help. just bought a roll of dynamat alternative. forgot the brand. big roll was like 25 pounds. so can you live with 25-50 pounds? i mean this is doing the ENTIRE car not just doors and stuff

also tire choice. in about a month or so, i'll be swapping in the old set of kumhos. i'm sure they will be less.

as for bass cancellation, the only thing that would do that is the inverse sound wave of the thing you are listening too. so maybe when you run oer the grates, they are generating an axact, or close to it, negative sound wave...
