Make Your Car QUIETER For $20!!!

Sound deadening your vehicle can be made cheap and easy with a small amount of soundproofing material on the right spots! I have a before and after sound test where I added some sound deadening material from Canopus inside the wheel well to see if it makes enough of a difference to make it worth it!

20mm foam or fleece in a very thin polyethylene film (plastic bag material) will be most beneficial, applied to rear surface of wheel arch liner. 20mm is minimum for absorbing tire tread peak frequencies which are usually around 800-1200Hz, but can only be used if there is room for it, as you don’t want to push liner into wheel travel envelope. Also road noise best measured only up to around 30mph, above that wind noise starts to become predominant. Plastic film is to stop the absorber becoming filled with dirt when wet, reducing absorption. Sound deadener or damper pads are best applied to the body in flat areas. I did vehicle NVH for many years in a previous life. Hope this helps.

[@soundproofguide]

Keep in mind the logarithmic scale of the decibel measuremnent system. A noise reduction of "only" 3 decibel is equivalent to a reduction of 50% of the sound intensity. A noise reduction of "only" 2 decibels in your case is equivalent to approximately 33% reduction of the noise intensity. It's like having 2 radios broadcasting white noise instead of 3. So really it makes a nice difference, and for only a couple of dollars too, it sure makes it worth it

[@allicks9220]

I have successfully removed a LOT of drone noise and NVH (noise, vibration and harshness) from my car after doing four things that made a big difference. (And I had like everyone else started off by trying to get things quiet using butyl mats/dynamat etc. I realised that that had a very limited effect and beginners usually end up sticking down way too much of the stuff and later regret it because you start thinking how much you’ve weighed the car down by. And a year or three down the line you end up taking two thirds of it back out - or trying to). Here in England I run a 2011 Ford Mondeo (Fusion) estate/station wagon. MY FOUR BIG TIPS for INSTANTLY reducing noise (REMEMBER - you are NOT going to get your sub-$25thousand dollar car to hush like a Bentley. BUT - you can get a LONG way towards it.) NUMBER ONE - REPLACE YOUR TYRES. If you want quiet, you need to LIFT the car further away from the ground and have less tyre in contact with the ground. So run NARROWER tyres with a TALLER SIDE WALL and if you can a SMALLER RIM SIZE. I replaced my 215 55 R17 tyres with 205 65 R16 tyres on replaced 16 inch rims. This dramatically reduced the rolling drone of the tyres on the road and gave a softer ride because the taller side wall raised the car further above the ground as well as reducing the contact with the ground. Yes you will get less of a sporty ride but I’m not interested in a sporty ride. NUMBER TWO - INSERT SURGICAL TUBING into all your door seals. You need to improve resistance to outside sounds coming in. Adding surgical tubing into all your door seals makes them nice and snug. Don’t go TOO tight though - get the right tube width - or else you won’t be able to shut the doors and you’ll feel real dumb. NUMBER THREE - Buy cheap ‘RECON FOAM’ cut it up into small cubes and shove it compacted in all the empty cavities under the trim around the console, footwells and glove compartment. You wouldn’t believe how many just open holes there are in that area doing nothing but causing sound from the engine and up from the ground to reverberate around. Foam (NEVER USE SPRAY FOAM - it will enter places you really don’t want it to get and you will never get it out in the event of a repair requirement) dampens all that NVH and contributes to the multi-pronged solution we are going for. You need to do a LOT of things to add up to removing those decibels. NUMBER FOUR - Go to the back of the car. On most cars under the rear bumper on the left or right corner area hidden away you will find a one-way ventilation flap on each side of the car. These are interior pressure flaps that allow air to escape from the car when the doors are closed and to allow ‘used’ air to escape from the cabin as new air enters from the front air vents. BUT they usually are located behind a very large cavity that sits adjacent to the rear wheel arches. In some cars you can reach into this large empty cavity through the back hole at the rear of the small felt door/closet you find in the left or right wall of the boot/trunk - the little hidden hole you might put an emergency traffic cone of yellow jacket in for example. I discovered one of these cavities causes a LOT of droning noise. The noise from the rear wheel comes straight through them, reverberates and comes out through the rear air escape vent. FILL THAT CAVITY UP! DOn’t fill both - you need one to maintain the ability to release the cabin air pressure remember - and often the fuel fill area prevents access to one of the cavities depending on if you have a left or right hand drive. But if you can get access to one side - fill it up tight with old rags, recon foam, old pcarpet that can be scrunched up - you want as much as possible to remove cavity space that creates reverb. Use anything not too heavy but DENSE. So recon foam, being more dense, is a lot better at dampening and muffling drone that say bubble wrap. Pack it in tight - and there’s room for a lot of foam and rags in there. This for me REMOVED 80% of the heavy drone in the back of the car - particularly on long highway journeys. NUMBER FOUR POINT ONE (!) Not essential but this improved my car dramatically - If your car is one of those that tilts down slightly towards the front end (to allow for the backend to dip slightly and the car to even out when the trunk is fully loaded) buy a pair of polyurethane lifting spacers to sit at the top of your front struts. Your garage can fit them for about $250. They again move the from end higher off the ground, away from the noise of the road. So coupled with the tyres we’re really changing how close we are to the noise of the road. Plus they make the car sit more evenly and look a lot better. These are my main tips for really getting to a quieter, pleasant drive. And they have really worked for me. I wish you all the best with your own particular car - every one has its quirks and every one will have slightly different solutions. But persevere and you can get a nice result.

Another way to reduce noise: Make sure your tires are good and balanced. My tires are nearly worn out and I always notice how much quiter and smoother it is with new freshly balanced tires.

[@soundproofguide]

Very true! Also the type of tires will make a big difference! Thanks!

[@michaelrobinson9643]

Tyres have a number of variables to manage that will influence Noise, Vibration. 1. Tread pattern and wear - noise magnitude and specific resonant frequencies for certain speeds - some are renowned for horrible noise. 2. Balance and air pressure - suspension bounce, and how well the tyre mates to the road dramatically impact vibration and thus introduced noise. 3. Tyre wall height. Lower profile = louder due to higher rigidity. 4. Tyre width. More tyre on the ground = more noise 5. Tyre compound. The hardness will alter the level of sound When shopping to replace your tyres it is REALLY helpful to investigate the quietest tyres for your vehicle that also still meet your driving needs and expectations for climate, life of tyre etc. Final tip, ask/investigate tyres different to your stock dimensions but still compatible (eg wider/narrower) because the more common a tyre is the cheaper it usually is. EG my car tyre costs $450 but if I buy the one 1.252cm wider it is for the most common vehicle in my country and only $200 for the same model.... economies of scale and competition at work :).

[@ScottoGrotto]

That’s a significant reduction in decibels for one area of treatment! Quieter tires of course help here too. I switched to Michelin pilot 4 A/S, and my 2002 WRX Wagon became a lot friendlier on noise! I did the whole back of the car treatment up to the front seats to quiet the interior from my aftermarket axle back muffler :) I’ve been meaning to get around to the front of the interior for awhile… Looks like a good product you found. I used a butyl damping layer with closed cell foam adhered to the top. Layered up the butyl till it passed the rap test in an area. Then applied the foam layer. Thanks for sharing your experiences, cool videos!

[@grahamtricker4103]

The human ear can just about perceive a 1dB change, so 2dB is going to be pretty insignificant. Certainly not worth going to all that trouble for 2dB. Changing the tyres to a quieter tyre will have more of an effect on Road/Tyre noise, all be it a more expensive solution.

[@OopsWhatIMeantToDo]

One safety tip: If you don't want to use or invest in proper lift stands, you can slide them under the frame (close to jack) as a safety measure. If the car falls off the jack, or the jack fails, it will fall onto the inflated tire or rim before crushing you. You might end up with a ruined tire or damaged wheel, but you should be fine. Plus, as the tire is rather wide, it will allow for a sideways slip (to some extent), not just up and down. As I have lift stands, this is something I always do when changing a tire roadside.

[@ckm-mkc]

Stands are a must, a friend was killed when his jack failed. Hydraulic jacks are actually more dangerous than the the OEM jack as a hydraulic failure will cause it to collapse instantly. And the tire under the car is something I always do, even with stands......

[@kekrikekkuli3359]

Try noice cancellin with amplifier. Mic or speaker (as a mic) connected to car floor (cone pointing floor) and conneted to amplifier. Subwoofer and speakers from that with opposite phase and you can adjust volume with speaker level adjustment and adding more or less mass to mic cone.

[@MrROTD]

If you use this stuff try putting it in places that are flexible plastic stuff like door pockets, dash and center panel, door panels in the interior etc, you can hide it quite easily by tucking it under or in these areas, makes a big difference and it doesnt take much to dampen the sound a bit. A problem with putting this in the wheel wells is these areas need dissasembly to maintain the car for instance some lights and evap equipment requires the liners be removed to replace bulbs or parts. if you can avoid covering up the fasteners its ok.

It was a great start. I may purchase another Noico kit and try some other areas. The main reason I used so little on the liners was that I only had a few pieces left of a small 10 sq ft kit, and the rest was used on both hoods. Seeing the proof, I wish I purchased a larger kit to continue in the cabins.

Did you perceive a difference in the tone of the noise aside from the magnitude? Absorption material will enhance your result where you added the constrained layer damping material. I'd expect less vibration and resonance from the material you added. A closed cell foam (hydrophobic) with adhesive backing applied through the wheel arch as fully as possible will make more difference in blocking the noise transmission - particularly with a mass loaded layer separated from the arch metal (dynaliner for example). This can be done from inside the vehicle and enhanced by layers under the external arch lining.

If you're not using a jack stand, the jack that comes with your vehicle is going to be more stable and reliable than a hydraulic will. Hydraulic jacks are meant to put cars on jack stands. They are not meant to hold the car while you're working underneath. Obviously, supporting a vehicle by any method requires that you have the wheels at the other end locked, like with the parking brake or with wheel chocks.

You noticed that too? 😁 Yep. Imagine going through the effort to jack the car, remove the tire, breaking off a clip, then wondering how you'd get the well plastic firmly and safely back into place so you can use the car.

[@3rdclasstatamahindrabajajREtvs]

Dosent it cause rusting ? Water splashes, accumulated on the material edges ?

[@Zgurkogel]

That's the first thing I thought of, as trapped water WILL cause rust. Very bad idea. Better to take the interior out and place damping materials inside the car. Yes, it's far more labour intensive (ask me how I know) but definitely worth the effort.

[@3rdclasstatamahindrabajajREtvs]

@@Zgurkogel agreed. It is better to paste it inside. Remove quarter panel trim and paste it. But, i have done long back. It doesn't makes huge difference.

[@paulparoma]

Good haircut, good clean shirt, you speak well and didn't do silly things for the clicks. Good job!

Anytime you work near or under a vehicle it should be on jack stands.

[@Jestey6]

To quote Soundproof guy “ a difference of one, or two decibels”. Something to consider perhaps ? A skilled listener is supposed to be able to hear changes of 1dB or more. Less skilled listeners need more like 2 or 3 dB before they are sure there is a difference. (This is measuring source signal amplitude, by the way, not acoustic power.). Mind you there are other considerations here. If we hope it’s going to make a difference, are we more likely to think it does? Personally I’m not sure it’s worth the time and money……

[@JasonWW2000]

It really depends on how serious you are about wanting to make your vehicle quieter.

[@Jestey6]

@@JasonWW2000 I suppose it does. However, I suspect that most rate how ‘quiet’ a car is as an important aspect. Especially when choosing a new one, and they will take this into consideration, when watching reviews, and driving the cars in their ‘short’ list. I know I did. For those who have unfortunately ended up with a car that they wish was quieter will, perhaps having watched this video, be tempted to try lessening the sounds by sticking sound deadening material in the wheel arches etc. My observation was, that that the improvements might not be as effective as anticipated, if the facts I listed, are taken into consideration.

[@JasonWW2000]

For some reason I just assumed that everybody watching this video is at a point where their vehicle has tire noise that is bothering them and they want to fix it. I don't understand the comments where people say it's not worth it. Then why are you here watching the video? Lol. I know people who spend hundreds and even thousands of dollars to make their vehicle quieter. I'm trying to keep my soundproofing budget under $1,000. The guy in the video is doing it super cheap and people are still saying it's not worth it. It cracks me up. 😂

[@JasonWW2000]

​@@Jestey6Also, keep in mind that the guy in the video is using a very basic SPL meter as opposed to an RTA which allows you to see all of the frequency range. He averaged a reduction of 2 dB, but we don't know at what frequency. At some frequencies there may be no change and at other frequencies there might be a big change. Maybe 3, 4 or even 5 dB. We don't really know because he isn't accurately measuring it.

[@chuckwalla2967]

Hondas in general are notoriously noisy inside. Has been that way ever since they started selling cars here.

[@chriss4365]

My truck has insulation in the doors from ford. The wheels have nothing. Blasting music and you don't hear the tires anyways lol.

[@agrubera75]

You should have soundproofed the whole car including under the boot trims, door trims, footwells, under the rear seats, the hood and boot door also. I did all these from 20 sq metre of sound deadening stuff and now my vw golf sportline estate (sportwagon) is quiet as our Audi was.

[@soundproofguide]

Nice! Did you notice a decline in fuel economy?

[@hlcepeda]

He was focusing on the wells for demo purposes for viewers. Doing other areas is a given.

[@agrubera75]

It doesn't affect fuel efficiency. Not sure why it would it's only 2kg extra weight.

[@jollyjohn6403]

What happens when you stick that material inside the tyres? Will it reduce tyre noise?

[@aloisius4188]

If you do this, you will NEVER be able to properly balance those tyres.

[@jollyjohn6403]

@@aloisius4188 why? It's stuck to the inner tyre walls. Wheel balancing can be done after that.

[@AisuruMirai]

Some tires actually come with foam stuck to the inside to reduce noise. Using soundproofing meant for metal won't really do anything but add weight, though, I think.

[@menguardingtheirownwallets6791]

Toyota asked customers if the RAV4 was 'too loud' and most said 'Yes'. But when Toyota asked those same customers if they were willing to pay an extra $40 to cut the interior noise by 50%, almost all of them said 'no', they would switch brands to an inferior automaker rather than pay $40 for a quieter RAV4. That's why Toyota won't make quiet RAV4s, the customers just won't pay the extra it will take to make them less loud. If you want a quiet Toyota, go buy a Lexus instead.

[@TunekoLtd]

If you find even smoother road dB will drop even more. Not saying the dampening does not work but testing is done in a very bad way to tell anything true of the changes impact.

[@soundproofguide]

Sad to say but I was on a “good road”. We have many bad roads. Lol

[@TunekoLtd]

But the videos are not taken at the same place. so values are not comparable. start of measurement should be always same place, same speed, same outside temp as it impacts tire softness, and even wind as there comes whistles etc. No other cars around so best time at nigth if there is a lot of traffic otherwise in your area.

[@alp0278]

Wouldn't that cause rust?

[@soundproofguide]

It will cause rust if there trapped moisture in between the material and metal. That’s why it’s important to make sure the surface is clean and dry.

[@Krakzzz]

My opinion: the subjective effect is greater than the decibels The noise is not only less, it is muffled deeper - this is perceived as less unpleasant

[@soundproofguide]

Agreed.

[@philtucker1224]

How come your car can run without the drivers seat belt engaged? Have you removed the safety relay?

[@JasonWW2000]

Seat belts should not have any effect on the way the vehicle runs. If yours does, that then it might be your specific model of vehicle.

A larger jack (than the car's own jack) makes little difference to safety. A jack-stand (AKA an axle-stand) is the proper way to ensure a higher degree of safety (or at least, a lower level of danger).

[@jdc212]

As a rule of thumb, a human can detect a 3db change in sound level. So....that's a start.

[@PatrickjoosJoos]

You're better off applying the deadening material to the fender liner itself and not the body underneath. My 5series had sound deadening quilts on the fender liners, my 3series did not. the difference was profound. I added it to my 3series after examining the treatments done on a Bentley, 7series and a Roll Royce. All had soft quilted material attached to the fender liner and some had deadening adhesive pads on top of the wheel wells inside the engine compartment. Assuming that these companies did testing before applying the treatment, decided that adding deadening to the actual fender liner was most effective. The fender liners of 3series fit flush against the steel wheel well of the car. The adhesive dampening used in this video would have been difficult or impossible to make fit. Instead, I used a spray on product directly on the posterior plastic fender liner *not the side facing the tire. The result was significant but the sound coming from the area of the car was still not as quiet as the 5series. I later added adhesive inside the engine compartment -on top of the wheel well. The results where hardly noticeable. Note: the 3series had factory sound proofing in the foot-well of the cars interior that was similar to that in the 5series.

[@psdaengr911]

1. Don't speak during a sound level check. 2. Indicate what curve the meter is testing with.

[@montanawhite5699]

My wife has a 2012 civic. Loudest car ever. My 89 bronco with mud tires is quieter. I’m 100% serious.

[@schifoso]

I stripped the interior of my Honda Pilot and used Dynamat and sound deadening foam throughout. It only decreased road noise a little bit. The upside was that the sound system sounded a lot better and the crappy subwoofer actually became noticeable. Anyways, putting sound deadening material in the wheel well should have been my first attempt as that's where most of the noise comes from. Don't know why Honda has never addressed their issue of excessive road noise from the tires.

[@mikej6544]

Turn up the radio

[@JasonWW2000]

If you can make the car quieter, then you can turn down the radio while still being able to hear it just fine. It makes for a much nicer experience.

[@mitchd949]

It's the vibration of metal panels which are all part of the car chassis/body making it seem that your inside a drum. Applying the sound dampening pads on the metal panels diminishes the vibration. Putting the pads on the plastic wheel liner did absolutely nothing.

[@aakudev]

Yes, was wondering do we really require on the plastic, when applied to the metal already.
