You would have to look into what all needs removing, but if the punks at the local stereo shop can do it, you should be good to go. Its really not too bad. Like STEye said- it makes a nice weekend project. In fact, any time you pop off a door panel or even a speaker panel, putting dynamat or similar down is a good idea imo.
Idk why I havent thought about adding my own sound deadening, but as I said- its really not the road noise that bothers me, just the rattling parts.
I'm going to start thinking about adding dynamat to some key areas of my Impreza. If anyone does actually start doing such a project, let us know how it goes.

Also- undercoating can help with road noise. I undercoated the entire rear hatch area on the CRX. That was messy. But it sure dampened that noisy little car down a bit.

In my experience, this car is noiser when it warms up in the morning. The engine/cvt are still brought up to working temperature. After a while, it's quite ok. Maybe I get used to it already.

Also, I came from Toyota Camry V6, I didn't satisfy with Impreza's noise at first place.

indeed, the engine itself is noisier during the warm up period (first 1-2 miles) in my experience. after which, the power/drive train are pretty quiet, IMHO.

Toyota, i admit, does a great job on making cars with less engine/road/wind noise in general from the corolla, all the way up their Lexus vehicles. but IMHO, the tradeoff is less connection to the road... (not that it's impossible to give yourself a quiet car with good driver feedback...but at this price point, i found you got one or the other...still relative to what you get in this price range)

Auto Week's review thought it might be noisy too, until they tested it.

"I have always thought Subarus were a little raspier than other four-cylinder engines. So I got our expensive decibel meter out and measured sound. The Impreza got the following: 40 dB at idle, 66.1 dB at a steady 60 mph and 72.1 dB at wide-open throttle. Some recent cars I've also sounded out for comparison: Buick Regal GS: 43.7, 65.0, 71.9; Volkswagen Passat TDI: 48, 66, 69; VW Jetta GLi: 44, 66, 75. So it's quieter than I might've thought. "

i wonder if these are on smooth road, or ???

it seems there are different things than contribute to noise levels: wind, engine and road noise are the big ones i can think of.

i think for the Impreza, unless under full throttle to accelerate, it cruises quietly and the lack of insulation allows rough roads to give a fairly high road noise level...but nothing too different from other small cars i test drove and have driven in previous years. (some better, some worse...)

Was that exhaust noise in decibels or what? If you put the car in neutral its still just as friggin loud. The ENGINE IS THE QUIETEST PART OF THE NEW IMPREZA.

I read that as well.

No way is the Impreza quieter than a VW GLI. I'm wondering if they tested a sedan instead of the hatch. The Sport Impreza is way louder than a VW GLI.

There's different ways to measure sound, involving weighting different frequencies. Low freqs can be quite loud, and you won't notice them. Road rumble falls there. Freqs around the human voice (1kHz) are easily noticed, and high freqs (13kHz and up) are in the range where even quite young people are suffering hearing loss. Depending on the weighting used, your perception of loudness will differ drastically with a machine's.

Having tested about 5 different manufacturers before settling on the Impreza, I am of the opinion that many new vehicles have poor sound insulation.

Today, I noticed that I can hear the petrol swishing around inside the fuel tank.

I noticed it in my last vehicle too but that was a VW T5 Transporter with bare metal in the back.

I would certainly be interested to see how easy it is to strip the carpet and door panels out to put some dynamat or equivalent down.

The noise levels are far from unbearable but on the motorway it is almost impossible for people to understand what I am saying via the bluetooth. Plus, having a quieter cabin would reduce fatigue on long trips for those of us who spend alot of time in the car.

this!!!!. do you have a hatch or sedan? i know in the hatch, if you remove the carpet to reveal the spare tire, it is mostly bare metal. i think sound dampening would help here.

some wind noise is impossible to tune out, without adjusting insulation of the doors and windows or improving aerodynamics.

But but but, insulation adds weight, might as well take out the jack and the spare tire while you're at it too. But seriously I don't understand how people can gut their riced out car and use it as a DD.

I had test drove both the sedan and hatch and the sedan is noticeably quieter with an insulated trunk.

I find the interior of my Impreza to be downright silent...but then again my previous vehicle had a Cold Air Intake, cat delete/test pipe, and 3" exhaust. It's all relative.

I find the cabin of my sport premium to be quiet as far as road and wind noise is concerned. It's far more quiet than my 02 cougar was or even my mother's 07 Mazda 3 hatch. The engine noise, on the other hand, tends to be fairly loud especially when reving above 2500 rpm. The car has also developed an annoying dash rattle within the first couple hundred miles. Overall I would say that feel good about the cabin noise level.

Where is your dash rattle coming from? ( just curious if u can localize it & wondering if there are common rattles)

Road noise is much better than my '08 STI hatchback.

I have a dash rattle as well (not to mention several others ughh). It sounds like a coin rattling around in the radio area, tends to reveal itself most on bumpy stretches of highway.

As far as I can tell, it seems to be coming from around the upper/center of the dash around where the temp/time display is. I've tried to apply pressure to the hard plastic trim around the display while its rattling to see if stops, but it doesn't help. My rattles seems to be something inside the dash, not the outer trim. I'm not about to rip my dash apart to see what it might be though.

If it's repeatable bring it to the dealer. They should fix it for you under warranty. They'll probably hate you for it, but at least you'll get it taken care of.

Agree with ST: If its repeatable, bring it to the dealer. Mine so far aren't repeatable after the car warms up which is a good and bad thing...

just picked up my '12 Impreza 2.0 Premium from the dealer. Took it for a test drive specifically to test out the cabin noise. I didn't notice anything that would worry me. It seemed just as quiet if not quieter than my 2007 Civic LX.

I tested it with the windows up and down at highway and city speeds. I didn't notice any excessive nosie
