Sound Deadner

It's a pain in the ass to apply and it won't work as well as you hope it will. It's easier and more effective to just turn the music up.

Turn the radio up, and get some moving blankets. Just lay them on the floorboards and possibly the trunk if that's an issue.

>>17739011
fuck no its dead weight.
I just installed a loud exaust so most of the road noise is nice.

So there's two different schools of thought to applying sound deadening.

There's the autistic audiophile method, and then there's the "I just want things to be quieter" method.

>Autistic audiophile
This is dead weight if you're not looking to have the absolute best sounding stereo possible, because you aim for literal 100% coverage of all panels... roof, floor, doors, and so on. When you deaden literally fucking everything you can control the sound of your radio much better, and you can go deep down the rabbit hole of eliminating resonant frequencies and standing waves and reflection, etc. etc.

>I just want it to be quieter
This method you still buy quality deadening for, but you really only need like 50 to 60% coverage on panels, dead center. This will take the edge off a lot of road noise. It also depends on the type of vehicle, for instance if you drive a pickup truck, pulling off the rear panel of the cab and slapping a big square of deadening there is minimal weight gain for what will be a noticable drop in sound, as that is the "noisiest" panel on the vehicle, generally speaking. Different body types have different properties like that.

Either way, don't buy shitty sound deadening.

>>17739011
No, because I just bought a modern car that has insulation in it already.

Put an aftermarket fiberglass trunk on my Miata and the sub I have in the trunk make it rattle like crazy. Got some Noico 80m mil sound deadening and put it on the center section of the trunk where it rattled the worst. I was hoping it would cut down on the rattling a bit, and it sure did. It's a night a day difference. The trunk still rattles a tiny bit with any heavy bass, but that's because there were some spots I couldn't reach because of the design of the trunk. I noticed a huge difference from in the car. The bass is so much deeper and sounds a lot more clear. I still have a lot of the stuff left, so I might put a little on my speaker grills since they rattle a lot with any heavy bass.

Like other people said, the stuff is really heave, so you'll be adding a fair amount of weight. In my situation, it was worth it to me. Put it on a fiberglass trunk, so the weight isn't much different than the stock trunk. This one might weigh a couple pounds more, but the trade off is worth it to me.

>>17739072
also after the first 50-60% coverage you fall into the land of diminishing returns

>>17739127
cause i drive a roadster and I hear everything any way.
And it the burbles and pops are great

>>17739072
So i just want it to be quieter, I'm assuming doing the doors and trunk will cut down the noise? Is the noico sound deadening or should i go for like dynamat or other known brands?

>>17739310
Have some consideration for your fellow man, or don't be surprised when you find the top slashed.

That "sound deadener" you're referring to is actually only for vibration, it doesn't block noise it just reduces the noise generated by vibrating panels. Follow the link above if you actually want to reduce noise, I fell for the dynamat meme years ago and was severely disappointed when it made basically no difference.

Better off getting sound isolating all weather mats to cover the floor much as possible and calling it a day.

If this kind of thing is important to you, buy a car with a less noisy interior stock. Most newer Toyotas and especially Lexus are quite a bit quieter inside than most cars. Like a Camry / Avalon / GS / LS.

Should i go with dynamat than? Or is the generic shit okay?

>>17741911
Noico, Dynamat, Fatmat, Secondskins, etc are all good material.

I have experience personally with Noico as of late. Have not used the other three in years, but was surprised by Noico. It's about 30% cheaper than Dynamat, yet it quieted my cars just the same.

Yeah, and its not very effective unless you integrate it directly into the frame, which means removing heaps of paneling.

Even then its not really worth it, look at getting new tires and or suspension, both of these things will have a more drastic effect on interior cabin noise.

Its fine for a track car

But my daily needs to be cheap, quiet , comfortable and an audiophile grade sound system to enjoy while driving

>>17739011
Shit get a fucking land barge if you want quiet daily on the highway. Town Cars get 26mpg quite easily my ls400 managed 25 hwy. But Dynamat is great for sound deafening. If you want your car to be cooler inside use peel and seal aluminum roof sealer. Ive done it in interiors of old cars with no A/C in florida and everyone says it works well.

>>17739011
Yes it does work.

Even just putting a square in the middle of a large piece of metal (outer doors, the roof, under the carpet, on the trunk and panels) will noticeably change the tone that the metal reverberates.

However that's not where most sound comes into the car. It'll help more with sound escaping, but won't improve DB's.

You would need to isolate the cabin more from the outside (feel your keyholes and handles with the air conditioner on full. air will come out) to actually improve sound quality from just deadening.

It does make your far feel more quality when going over bumps and shutting doors. More of a thud.

But first:

Get quieter tires
Inspect your suspension for worn and seized parts.

>>17739011
COVERING 100% YOUR PANELS WITH DYNAMAT IS THE WRONG WAY OF DOING IT!~

>Has anyone used any type of sound deadner in their vehicle?
In my car, the choice of tires matters a great deal as to how much road noise gets into the car. No doubt you've experienced the difference in road surfaces on the noise you hear. Concrete versus asphalt. Fresh asphalt versus old asphalt. New tires versus old tires worn down to the stiffer block sections. And of course tires that are deliberately made to not be so noisy at the cost of maybe a little performance.

If you run MPSS tires, then of course you'll have a lot more noise. If you insist on MPSS all year long, then asphalt sound deadener isn't enough. You'll have to dampen out the way sound travels inwards with something more aggressive like 3M 2552 Foil so google that. It's made with sound dead aluminum alloy which is not like your usual aluminum alloy. It's the type of material that reduces longitudinal sound propagation on a beam, rod, or surface. Remember to use walmart.com as your baseline price comparison as not everything in this world should have amazon as the baseline especially if it is a chinese copy made with normal aluminum. I have engineering samples of 3M 2552 and it's pretty good stuff.

See this archived /o/ thread as an example of sound deadening threads.

Thank my man this has definitely helped, i think I'll go with the new tires and go on afterwarda

>>17751207
>i think I'll go with the new tires
The higher speed rated tires have stiffer blocks, so if you don't need to go high speeds, get the lower speed rated tires with less stiff blocks. As you can see in the picture at http://archive.4plebs.org/o/thread/15364893/#q15373336 when the tire meets the road, it compresses. That absorbs not just the impact but reduces the amount of road noise. If the rubber was stiffer, it would compress less as you can imagine from the picture.

Many years ago during the Monster Cable fad craze that had so many people recommended monster cable to each other, that company came out with power cables to replace those you use with your home audio units.

The salesman tried to get me to buy those $29.95 power cords. He talked about how the shielding made sure your power was clean and didn't stress the power supply. I simply cut him down with the comment that the AC power lines in the house going up to the wall socket are not insulated and shielded, so it makes no sense to shield the last few feet of AC power lines to the gear.

Not that guy, but even small cars have have a huge outdoor sound depending on how it's done. Some audio car mods are made with extra speakers. The normal set of speakers are for when the is being driven. But the extra speakers are for when the car is parked with engine / extra alternator running to drive the extra speakers.

The extra speakers are mounted in the doors and rear hatch lid. Other speakers are exposed by opening the hatch. With all the doors open, the car can deliver a good loud sound that has fairly good fidelity.

There's one well-off coworker that had lived that way for a long time until he got married. He didn't need the space or expense of an apartment. But the downside was that he had to commute from a much farther distance. He saved up his money and has a home and wife now with kids. 2 of which have graduated university already and the last one in school.

Not that any of you are retired in here, but in the winter time, many retired people from the northern states head south in their campers, trailers, and RVs. They winter in the southern states in large numbers. Many are multi-millionaires and there they are in their trailers. Of course, some of them end up buying houses and living down south permanently just to escape the winters in their retirement years.

>boxed 6x9s that you can set out
They are removable as in those old style furry wooden speaker boxes? The problem with the generic boxes is that they are not sized for particular speaker. Thus the speakers do not produce their best quality sound and best volume. In some cases, standing waves inside the box might even decrease the sound quality.

>>17754171
>This is exactly how my setup is.
All your speakers are mounted in the car like that? A car like that is meant to be a mobile soundbox with all doors opened. Of course it must have quiet exhaust and premium quiet serpentine belt along with extra alternator.

>>17739011
>Has anyone used any type of sound deadner in their vehicle?
I will be putting 3M 2552 over the rear wheel wells and the floor of the trunk next to the wheel wells. That will cut down some of the road noise transmitted into the unibody from the rear wheels.

I came to that conclusion by taking both KentuckyBro's advice in the archived thread and from looking at my car. Peering under the rear, I can see where the suspension elements are fastened to the unibody. Those points have the most road noise coupled into the trunk and thus into the cabin body since I'm basically sitting inside a tin can that is vibrating from the road noise.

The trunk lid is another matter. It's hard to put sound deadening material on it without the stuff looking out of place.

>>17755068
>Relocate it man, or try stuffing one under the seat, those Pioneer's only need 3 1/8" mounting depth
Those ultra-thin under-the-seat subwoofers don't work in a lot of modern cars that have electric seat options. Complicating matters is that seats are able to move up and down, so putting one in means the seat is raised up high and can't be lowered or tilted.

>>17754988
>Gotta wire up a beefier alternator one of these days, stock 63amp can't keep up if lights/heater/wipers are on
Yep, the basic OEM alternator in my midsize car looks kind of puny. I should look up what amperage it can deliver somewhere as the dealership is no help. Their parts department doesn't give out specs info unless the product is purchased from them.

What about dynamat?

Also, thick windows are one of the main reasons luxury cars are so quiet. So hard to match that

>>17764354
>thick windows are one of the main reasons luxury cars are so quiet
Rather than luxury cars having thick glass, there are different types of glass that don't transmit as much wind noise. Sound deadened glass is also in non-luxury cars. My chevrolet malibu 2016 has sound deadened glass. The front windshield also has the extra-hard surface layer glass (it's a sandwich like all windshields) to reduce tiny chips appearing from sand particles.

Look at the April 2017 issue of the Consumer Reports magazine. That is their annual car issue. There is a particularly good tire rating and comparison article in that issue. They tested the tires under similar condition with identical rim and cars and driver. This helps make for comparable rating results.

I wouldn't put anything porous inside doors. Water gets in there and needs to drain out. Anything foamy will hold salt water and can then promote corrosion and mold/bacteria growth.

>below the door panels
Anything you put under the door panels should not block any drains or be in a position that catches dirt (and thus mold) on any "lip" formed by the material.

they're very good for the price. in fact they're better than what you get in a $50,000+ lexus with premium audio (they use infinty ref)

That's assuming you hit all the areas that noise comes from. If you put all the coverage in just one spot, then there will be places totally uncovered.

If so, the imaging of those speakers is pretty sharp. I remember many years ago when I tested speakers for a room in my house. The Infinity speakers were too accurate and resulted in a tiny precisely focused sweet spot exactly in the middle of the sofa. I wanted a wider sweet spot that would allow two people to hear the stereo effect, so I opted for the sloppier Boston Acoustics towers. Those had a much wider sweet spot so that the heads of two separate people could be within the sweet spot.

In modern car premium audio systems, it is possible to electronically move the sweet spot from the center of the car and steer it to where the driver's head is located. Extra Accurate speakers would thus be used for that purpose. Of course, the other passengers would experience diminished audio quality as compared to a sloppier system or one that didn't have the sweet spot steered to where the driver was sitting. But no one sits in the very center of the car.
