Ford Focus 2003: Enhancing Cabin Soundproofing with Bitumen Mats, Foam, & Tire Considerations

Hello and Hello everyone, I have recently had a Ford Focus 2003, this is my first car, it is modestly modified to increase driving comfort, including soundproofing the door with bitumen mats and foam, and here are the stairs .... Somehow in the summer I silenced the door Ford was standing on wheels 15 alloy wheels on a 195/60 / R15 tire and after silencing the door I was satisfied with the results, there was indeed a difference compared to the factory, after installing 175/70 / R14 winter tires (I will only add that these matador winter tires as well as summer barums may be 71 db) it was louder, but it was still bearable, and then the decision was made to silence the walls of the trunk, and it gave a minimal effect, then I added one layer of bitumen to the front door and let go of the rear door, because I did not hear the effect, and here is my first question - is it possible that if winter 175 tires generate 71 db and summer 195 tires, so wider and in theory louder, which seem to have the same index 71 db, are simply much quieter as about that they are lukewarm? I will just add that winter tires and rims were bought new together with the rims and they are not damaged, and the summer tires have one season. And the second question - do you think it makes sense to play silencing the Ford in winter in a warm garage? Isn't it better to wait until summer? Can it turn out that after all these operations in the winter I will hear poor results and after installing the summer 15 suddenly it turns out that I am driving a Mercedes? ?
And the last question, if I have muted doors and trunk walls, what should I mute next to make it really quieter? I will add that I do not care much about the sound from the speakers, I think that the series meets my needs enough.
I will also add that my dad has a Mazde 6 mk1 after a lift and it is much quieter in it, up to about 100
kmh, however, the difference is that in Mazda it is completely quiet up to about 60, but then it is louder and louder and at 140 you have to raise your voice strongly, while in my Ford at 60 it is medium loud but at 140 it is not much louder, but by that too loud to be able to talk calmly or could it be the effect of silencing the walls of the trunk and the door? What we care most about is a tip, what can be quieted further, so that even on winter tires it is quiet. best regards

Long topic, you have one post so I will dedicate myself and sit half a night for a few explanations
Especially since you gave a specific description ...

It makes no sense to pack 2-3 thousand into a corpse. into a comprehensive profi suppression because only such an effect will give something. I was so smart too. A non-returnable job for ideas. But I am not right.

Andrzej, maybe the muffler farts or humming bearings, or the clatter of the diesel or the howl of the box. Ooze the meaning of the project, I want to let it have. You have a comparison to Mazda 6 or Mondeo, it is not known what engines, gearboxes, general condition, generally one post.

Thank you very much for your quick answer, in this case I will wait for a more specific answer from you, addressing the state of Mazda and Ford, in general, both cars are in perfect condition, for me there is a 1.8 tdci engine in my Ford (unfortunately), and in Mazda 2.0 cdti, i.e. both with the worst reputation in these models, both cars are station wagons, Mazda is year 2007, returning to the topic (I am departing a bit), I wanted to add that I can buy from a friend from a warehouse, purchase of bitumen mats from the app brand for about PLN 3 for a 25x50 cm sheet, hence I can use even about 100 pcs, unfortunately the foam is not that cheap anymore, but as far as I know, the bitumen mat itself, unfortunately, does not mute the cabin and apparently stiffens (if I am wrong, please correct me. I will add that 90% of my routes are city and suburbs and the maximum speeds I reach there are 80-90 and I wanted to mute the car as best as possible when it comes to Mr. Andrzej's comment, it's true that it's a corpse, but I think that it is not in this version and condition, I have I drive 80 thousand mileage there and there is documentation of the ASO service in Lodz, hence I think it makes sense to pack money in it, I'm going to drive it for at least 5 years, the idea of mute came from here because I have an internship in a Mercedes service on a daily basis and I always dreamed of the car is so luxowe, it is true that it is only a Focus, but silencing is a step in this direction ? Regards.

spend this money on adding the dead bodies after the sale And buy a merca.

But I am not right.

I used to silence Lanos, using foam mats (something like travel mats). They lined all the doors, the cabin / engine partition, the rear seat and the shelf (sedan version). Three days of work and a noticeable effect, also in the opinion of others.

In this case, thank you for the answers, although I did not find out what I asked about, because I can see that the opinions are divided as to the sale of the car - at the moment I am not going to do it because I want the car to be better quieter than also more expensive to maintain, As for Mr. Andrzej's comment, maybe you are right, I deal with cars over 100,000 zlotys on a daily basis, and yet I do not consider Ford to be a corpse, not because I cannot afford a better car, just my Ford is technically and in terms of paintwork a sight car and I do not want to buy, for example, w221 below, for example, 50 thousand to get into a mine. best regards

You also need to dampen the bulkhead wall well. Apart from that, there are other methods for the upholstery, it is best to remove everything and give the mat a roof, a floor.

Apparently, these cars for 100 sticks are stuck together.

A correct comparison only on 221 ke you need to give '' a little more '' or buy a tackle.


First of all, the door seals must be as new or new - it gives a lot.
Next soundproofing of the floor and bulkhead.
Anyway, you have a clatter, it will always be a clatter.

I write that there will be no eagle from the hen.

Hello, thank you for the answers, my focus is already demolished in a warm garage, and I can honestly say that the floor looks quite well-sounded at the factory, but the bulkhead wall is another matter, a bit of poverty, goal sheet metal here and there some sprayed bitumen, I would like to ask more Does it make sense to invest, for example, in stp or dynamata? This is an amateur mute, hence my dilemma, in general I do not have a specific budget, I want it to be good. And finally, I would like to add that in Mazda 6 2007 it is completely the other way around, the floor is muted but weak, but the diesel engine can hardly be heard inside but outside the chalas is amazing, unfortunately the air noise in Mazda can be heard terribly ?

To be honest, soundproofing the floor and wheel arches with bituminous mats and gms foam and 3 mm felt did not help, or I am deaf, I gave 3-4 layers of bitumen mat for the wheel arches and two here and there 3 for the floor, gms foam and felt. I have the impression that from about 100 km there is an almost imperceptible difference, but probably the placebo effect, the materials came to me about PLN 500-600

It was necessary to measure dB before and after. When it rained it should be quieter. Important bulkhead wall. Besides, door seals let out noise.

I said because I blended in so myself

I also added gms foam for the roof, and silenced the bulkhead wall, I decided that since I had already spent a lot, I will go all the way, I bought gaskets from the Mercedes w222 on scrap metal for PLN 50 and to be honest there is a noticeable difference, maybe it is not a gulf, but it is actually much quieter in the wet and when driving on the motorway, the noise is lower, in the city not a big difference, unless on a poor surface, then it is less noticeable, was it worth it At the moment I got around a thousand zlotys, the difference is small to 100 kmh but clearly noticeable on the highway above 100-120 kmh, and I think that the effect is cool, but unfortunately the price is quite high for the effect itself, as it is with, for example, the new Mercedes it has little soundproofing directly on the sheets and it is quiet and I have everything in the cabin fired with several layers of mats and is it louder?
