When it comes to car sound proofing I've done it all. What u done was add mass to the panel which you did not need. U needed closed and open cell foam to kill the airborne noise that you have. Added mass will reduce the resonance which was not your problem like older cars might have you have airborne noise. Also most of the noise in EVs come from the windows and tires so wheel archs needed attention as you can't do anything to the Windows. This is part why you found no difference and wasted your friends time. Don't waste your friends time.
You're exactly correct....adding in weighted mass panels to doors or sheet metal will generally not make the vehicle quieter but can change the harmonics to be less objectionable. The dB meter is still the same but your not getting resonance or a boomy effect. All these Dynamat type sound deadeners really came about due to giant bass speakers causing the cars panels to vibrate and buzz. High end construction equipment uses foams to help absorb and dissipate in cabin noise. The highest end luxury cars spend extra money on door and window seals. Essentially any opening or hole that can let air in lets noise in. Fender liners are now flocked with with looks like a carpet material to help absorb and lessen tire noise. Want a quiet ride?.....seal the cars cabin to the point that the car will float....it won't get any better than that.
The hatch is good to dynamat, as it gets quite a bit of wind and resonant noise. They're aluminum in Gen 5 Prius, and there's next to no noise isolation there. The aerodynamics definitely make it quite loud there. But you're right, the road from wheel noise is the biggest thing. On a freshly paved road, in EV mode, it's actually quite quiet. And the premium model that his friend has comes with laminated passenger and driver front side windows. This already lowers wind noise a lot for them.
I had an older Model S. Doubled up the door insulation, adding felt near resonating chambers, and putting ¼ inch Noico foam on the back side of wheel wells and body panels near wheels. Made a HUGE difference.
I used your tips and did the wheel arches, doors, hatch and hood in my wife's 2018 Kia RIO hatchback and measured a 7db average drop in noise. A very noticeable difference! Not bad for an economy car. I've done the same to my own daily driver, and have been experimenting with the butyl deadeners in my engine bay. I wanted to let you know that after 6 months of driving I can attest that using the butyl on my valve covers, intake manifold, engine mounts, alternator brackets etc, have not melted or caught fire. lol. They also have not made any noticeable difference, except when I put some directly on my high pressure fuel regulator, and hoses, and the underside of the plastic engine cover. They actually made a difference. I only mention it to you to let you know that the material does not burn, smell, smoke etc. Obviously exhaust manifolds are a no go, but just about anything else seems ok. Use at your own risk though. Thanks for the ideas, and tips that gave me the inspiration to experiment. Modifying performance cars has been my hobby for more than 35 years and I'm still learning cool stuff.
BTW on some of the more plastic cars, there can be roof seam gaps that create wind noise. If you put a rubber insert that, it quiets it down. Door seams too; my current car actually came stock with rubber seals that block the door gaps.
Quite cabin is a big selling point. So automakers would have tried their best. My Corolla cross Hybrid got some floormat like material for the rear wheel wells not plain plastic. They have cut corners in almost all places but curial places they have changed. It works. That car is quiet unless pushed hard
I have a 2025 toyota camry xse and it's pretty noisy on the freeway, regardless of what reviewers say. I added the sound deadening material like you did to the doors, and didn't see much improvement. I then used soundskin pro on all four wheel wells and that made a big difference. That one has some foam material to block sound, unlike the stuff used on the doors. I've now added the same soundskin pro on the doors, and that quiet down the interior some more. It also made the audio sound crisper/clearer. But yeah, I think in order to get it quiet, you need to use stuff that has a foam layer on it. I'll eventually get the full floor and trunk done, probably next year, it's $$$ lol
2010 civic feels like driving a tin can - put a tiny bit inside the doors and the upholstry guy put some on the roof while doing a headliner - going through the car wash was unreal with that thing - the dryer air sounded like somebody playing the drums
The biggest improvement I made in my Infiniti G35 was installing tires with noise canceling technology. Now all I hear cruising at 75mph is the sound of the air rushing over the body and that's very faint.
@ No. I mean from the weather after application. Some cars are manufactured with pieces of foam under wheel arches to prevent plastic vibrating against metal and some of those are known to accelerate corrosion along the metal edges of the wheel arches. Was wondering if you chose materials specifically to avoid this risk…
My 2024 Honda CR-V has some notable panel gaps, particularly around the hood and A pillars. Will covering those gaps reduce wind noise? I've noticed the wind noise is pretty loud at highway speeds.
Is this as effective as chaning single pane window's to double pane windows where possible? The 2024 VW ID 4, is otherwise a good car but with poor sound insulation, along with the Kia Nero EV from 2023
Do you know any affordable ways to sound proof a room that doesn't need drilling into walls and is easily removable? I wanna sound proof my dorm room but we aren't allowed to drill or paste anything that isn't removable in the dorm. And at the end of the school term we have to take it all down.
Rugs and soft, heavy materials (blankets, throws, pillows) anywhere you can will help reduce resonance. For sound “proofing” your best option would be to close the gaps around doors and other openings. They make foam, plastic guards and other products to do that.

@georgecarousos6735 perfectly said and correct!.

You added only vibration absorbing material.
Noise absorbing material you did’t apply. Something like foamed polyurethane or special carpet.
up to 5 db is significant, in my opinion
Could any of those materials trap moisture? Especially the stuff you put under the wheel arches…
It might If it’s not clean and dry when applying.
@ No. I mean from the weather after application.
Some cars are manufactured with pieces of foam under wheel arches to prevent plastic vibrating against metal and some of those are known to accelerate corrosion along the metal edges of the wheel arches. Was wondering if you chose materials specifically to avoid this risk…
@@soundproofguide So is that a ‘don’t know’?
I wasn’t commenting I was looking for useful information.
@@anonimushbosh Yes, some materials will absorb and trap moisture. Don't use those.

Have you tried ResoNix CLD mats?
Do you a video on exhaust drones on 4 cylinders lol
Some content creators are recommending weather stripping that compress easily and claining that is very effective
can you be a bro and point me to a video about that?
Yep, share the video ;)
Do you know any affordable ways to sound proof a room that doesn't need drilling into walls and is easily removable? I wanna sound proof my dorm room but we aren't allowed to drill or paste anything that isn't removable in the dorm. And at the end of the school term we have to take it all down.

Road noise mainly comes from your tires! Buy a better compound set of tires & that will cut road noise significantly!
So what’s the video about? Sound deadening the hood of a Tundra?
Hmmmm good question. In reality it’s to show people that not all sound deadening works for all types of vehicles.
Car manufacturers should treat their customers like thinking being and explain what soundproofing they use on their upper trims 😂
If it's 3 dB less it means its half the sound pressure
Have you ever Tried putting Sound deadening mats under the mats in the footwell?
There goes your mpg 😆
🤣
No more than your wife adds.
Moving studio
Installed it wrong. should have installed it on the inner side of the door.
It was on the inner side of the door.
