Sound Deadening Project

[johnloov]

It's just easier to remove the wheel on a jack and get full access. I tried that initially - you maybe able to do it - but it could be a hassle

I rode in the back of a brand new Honda Civic sport 2026 and it was gosh-awful road noise and it made me realize how badly insulated these vehicles are from the factory and I could hear a ton of road noise coming back from those wheel arches in the rear. I hope Honda figures out a low cost way without adding weight to really damp and isolate sound because it is Gosh awful..

I can confirm by riding in the back for the first time that road noise is coming from the rear wheel arches and trunk. It’s unacceptably loud. Feels like a tin can. And this is also a car on less noisy road tires than the type R.

Honda listen up and fix this on your cars moving forward !! If all other manufacturers can do this without adding much weight, do it! My ears are slightly ringing this morning, I can’t even remember and imagine how loud my type r used to be.

It is a Civic. They're designed to be low cost, fuel efficient cars. Except for the tin can body, those properties don't translate to the Type-R. You're going to hear every sound the road has to offer.

The tinnitus is real, and earplugs are your friend.

I keep a pack of disposable foamies in my center console for local trips, and a pair of silicone rubber triple flange plugs in my door handle for highway drives.
Until I get my car insulated, this is life in a Civic.

That’s what I call my tinnitus military grade I even talk to my self to make sure I’m hearing them and aren’t paranoid or part of my imagination! I use the earpro and go crazy because they go even louder!

The sound deadening was necessary for me - now it's a pleasure to roadtrip to track - drive home

I laughed at this thread when you first made it, but after 2 years with the car...I'm doing at least the rear seats and trunk. Highway drives suck.

I completed a layer of the Amazon Basics mat in the trunk that is visible by pulling up the floor mat and tire fixit stuff only. That did quite a bit for road noise. I'll likely continue with the wheel wells and re-assess but I'm much happier with the volume, now.

I am still debating if I want to do the front wheel wells, maybe only if I could pull back the rear half of the liner since I have no ability to remove the wheels. Do you think it's possible to treat that area by turning the wheel all the way to one side?
I want to treat the floor as well but don't feel like pulling everything apart.

Impossible to pull the liner off without removing the wheel. i tried, they have some dumb clip behind the wheel

You mentioned that you hear the engine more now. Did you find the humming/droning of the engine became annoying after you had treated the wheel wells and the floor?

 

[johnloov]

No drone of stock engine - everything was better - sound of engine ( minus constant road noise )

I am getting ready to start my sound Deadening project and have a few questions.
Does anyone have the size of the openings in the front and rear doors. I need to order materials to make door block off plates. I am going to do before, during.and after sound level measurements. I did change out my tires for.Kumho Ecsta S PS72 and that did help with some tire noise.
I plan on adding a CLD, CCF and 1" doubled scrimed Thinsulate. I have 1/8" MLV and will only add it if i am not happy with the results.

Good luck! Best decision I made so far.

Another major added benefit to all the sound insulation - is thermal insulation.

I didn't appreciated it until I moved to Texas. The car on a hot day is able to maintain easily amazing ice cold interior temperatures in the cabin and on road trips, the insulation keeps interior very insulated from outside temperature deltas. The car feels like a vault.
