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.
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
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
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.
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
Seems to me that’s treating the symptoms instead of the cause. Some tire brands or tread designs are quieter than others. Flat run tires with the thick side walls are the worst. Next check muffler noise.
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.
so if I followed your videos correctly I add some matts in the wheel arch in the metal and in the plastics and in the doors then it will be a lot right?
@ 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…
Cld products like the ones you used dont block noise. Theyre designed to reduce panels from vibrating. A proper sound deadening job is cld 1st, closed cell foam 2nd, and full coverage of mass loaded vinyl 3rd. Not doing all 3 stages is a waste of time and money if your trying to block road noise. People that put cld down and then comment about blocking road noise are full of it
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.
appreciate the effort mate, but sloppy job, you should have researched more and see that good results are requiring 10 times the effort and materials and a lot of attention to details...the sound passing trough the windows cannot be mitigated....but real results are done in 3-4 days of work with tons of effort...

I’m sticking with my noise-cancelling earbuds-it’s so much easier to adjust my perspective than to change the entire environment around me. 😄

up to 5 db is significant, in my opinion

I wish there was a company that would sound insulate cars in my area.
I'd like to see you test out a W140 Mercedes with dual pane windows.
I did this to my 2010 Toyota Prius did the trunk and use some foam as well much better

You added only vibration absorbing material.
Noise absorbing material you did’t apply. Something like foamed polyurethane or special carpet.
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.

@@soundproofguide So is that a ‘don’t know’?
I wasn’t commenting I was looking for useful information.
@@tomoxfford Yes, some materials will absorb and trap moisture. Don't use those.

Do you a video on exhaust drones on 4 cylinders lol
Road noise mainly comes from your tires! Buy a better compound set of tires & that will cut road noise significantly!
Have you tried ResoNix CLD mats?

Have you ever Tried putting Sound deadening mats under the mats in the footwell?
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 😂
Sound deadening material is not sound proofing material. You need closed cell foam or mass loaded vinyl.
If it's 3 dB less it means its half the sound pressure

Installed it wrong. should have installed it on the inner side of the door.
