Disappointed After Spending 4k In Soundproofing

Bmkia,

Very sad to read your feedback here.

Our motto is to provide the Best results to ALL our customers.
You could have contacted me if you were not fully satisfied with the results.
My regret here is Waiting to do your Doors together with 3M Roar buster to offer you a better deal.

We had the NON waterproof 3M version in stock then but i will Not apply it to the Wet wheel arches.
The water-proofed 3M material is now available.

Have you also considered what you are enjoying Now are is the COMBINED result of our solutions, which were determined by your budget then, therefore the Door SP was to be done later and the subsequent Dynamat application, esp.on the doors ?

KHAWWM has made a fantastic suggestion.
Lets arrange a Merry Mazda 3 Char Siew Makan at a at my place to test and compare results. I have a nice route.
Or, you may suggest a venue.

To make things more interesting, I will also invite 2 other Mazda 3 owners who had thier rides recently done with us,
Adrian ( remember him? He did his the same time with you) and Andrew.

All 3 are 2.0s with bigger noisier tires.

It may all come down to preference. I suspect they may prefer the Light, airy "Bigger" car ambience we gave them as compared to the "Heavier", high pressured cabin you seem to prefer.

However, if they prefer your results, I will UPGRADE them with the Same Dynamat Extreme you applied, FREE !

You can also test how much more 3M Roar Buster can improve yours.

Let us know when you are available asap so I can arrange a Merry Mazda 3 TT.

Those interested, ALL are invited to a SP shoot-out ....with delicious lunch, on me.


Cheers,

"Asia's Answer to BMW" is Wajunk, not Forte; haha...

This was my second car about 7-8 ago which was noisy; however, get myself interested
in the subject of sound proofing cars ultimately. Then, I sold it off & get myself a Hyundai
Sonata NF 2.4 - a damn quiet car from Kimchi. After which, I sold it off again & get a Toyota
Camry 2.4V - damn noisy 2.4 engine from Toyota which was also sold off last year. I did
my noise insulation with Desmond too - which was, well, with some improvement though.

Just my humble opinion.

That's why I suggest those who are interested in soundproofing of cars to have, at least, some basic understanding & knowledge in car acoustics, rather than just let the auto accessories shop owners simply "put" everything to you &
ultimately find yourself regret or not satisfy with the results after spending so much $$$$.

Just go google, you can find a lot of info on car NVH. In fact, if you have some basic knowledge in high-school level physics or an engineering background, it would be much easier to understand this subject matter.

Everything is just basic physics - no matter what marketing strategy one uses to "brand" or "re-brand" a product.
To me, structural damping + noise absorption are the two basic ways to go for, in addition to bearer.

Only one thing I still can't find for my car: replacement of normal tempered glass side windscreens with acoustic
windscreens. Acoustic windscreens are quite popular in the US & Europe.

Desmond, are you planing to bring in acoustic windsreens to us Malaysia car users? I don't find applying
security film (4mil etc) an effective solution since there is no absorption inter layer here.

Hi Khawwm,

Lol.... I am more than happy to compare the SP since we are driving (almost) the same car and share very low tolerance on the road noise from our Mazdas. Can you share what have been done to your car and how much you have spent to date? I already spent almost RM7K on the soundproofing of my car and can give you a breakdown as well.

And we need to test it on on highways where speeds of 110km upwards can be reached (recommend the NPE for this), not just bad patches of taman roads.

Hi Desmond,

I did contact you twice remember (somehow only got your attention when a negative feedback is posted up on the forum):-

1)After waiting 4 days for the foam to cure and finding out that my car then had a new annoying "chit chit chit" problem which was caused by your expanding autofoam and had to spend half a day back in your shop to locate the sound and clean up the foam. That was when Adrian was around but I don't think he soundproofed his car, more like fully autofoamed his car (ultimate package) and applied QuietDrive to his 4 wheel arches only. My 4 wheel arches was already dry then, but you said wait for the Autofoam to cure for a full 10 days and your 3M roar buster was out of stock.

2)Called around 2-3 weeks after that (since you said the foam will take 10days to fully cure), still no 3M roar buster and said you willl call me back when the 3M is in stock. Well, there is no phone call until hearing from you in the forum today.........

Btw, light and heavy is a matter of "perception". "Heavy" in my "perception" that the Soundproofing is working, you don't hear much (road noise/ passing vehicle sounds, etc) from the outside anymore and could enjoy your cars audio/music on a lower setting whilst "airy" means the soundproofing has a slight improvement only, you still hear much from outside your car. And what pressure are you talking about from a good soundproofed car? The one where your eardrums feel uncomfortable going up Ipoh or taking off from an airplane?? I dont feel any of that at all....

And your logic of a "shootout" at KL Auto doesn't benefit me at all. Can I get a full cash refund if Adrian and KHAWWM agrees/ prefer the soundproofing done on my car compared to theirs?

Hi,

Sadly I was ignorant and spent the first RM3.2K based on "recommendations" that was very expensive with only slight/ minimal improvements. Was disappointed after that and did a lot of online research on soundproofing the Mazda 3 and that is when I decided to head to KK Lau to Dynamat Extreme the car. I am no engineer as well.

Anyways, this seems to be a success case for soundproofing the Mazda 3.

hi Bmkia,

Yup, i also remember you telling Adrian you were satisfied with the improved Comfort and steering feel.

Since we are in the spirit of sharing, pop by and let your fella 3 bros like Adrian, KHWWM also enjoy the experience.

If they like it, i can upgrade theirs, with NO costs to them AND with all gratitude to you.

Cheers,

Desmond

btw, my phone was stolen and all the contacts with it. I dont back up
Bros, kindly send me a SMS to record your contacts again. Will back up this time.

Bmkia,

Just read your post again. Your benefits...That's fair and we want happy endings.

If both Adrian and KHWWM prefer yours and want to do the same on their ride, i will gladly remove our soundproofing materials from your ride and refund you in FULL the removed portions.

In fairness, since they are running on 17" tires compared to your 15", all tests shall be done with KHWWM's tires.

Sounds good?

Hi Desmond,

I'm reading this with utmost interest... Are there any side effects of having high-pressured but quieter cabin on a long journey...? In this case I would also know how do any of your Lexus customers feel about their long drive in a quiet cabin. I've been enjoying your work so far, but my main gripe is still on tyre and road noise. Despite having the quieter Michelin PS3s for some time now, at times I still get those irritating drone noise coming from underneath the car even though I have 3M Roar Buster installed. You know my sensitive ears. QuietDrive or SP Premium/AcoustiBlok undercarriage treatment or both...?

Not sure what when wrong but 1 thing for sure is that sound proofing doesn't make your Proton car as quiet as mercedes no matter how much you spent (sorry for being optimistic )...

Its only help in reducing/lowering/minimising sound decibel, there are alot of factor that contribute to noise....from the design, construction of the car body, (aerodynamic)....

Also as mentioned, different person have different sensitivity to noise level...(i am wondering before you purchase the car, sure you did test drive...'quiteness' should be one of the criteria you look into it right ? ...takkan after beli, drove sometime when tyre/bearing start wearing out and 'noise' level increase...than you think that put few K to 'seal' the car will make it as quiet as brand new again ??

Just my 2 cents.
