Title: soundproofing
Post by: Travis on January 30, 2023, 02:32:47 PM: HI does any one know if you can fit soundproofing material under the carpet on a mk 4 jazz ex.
Many thanks.

Title: Re: soundproofing
Post by: Kremmen on January 30, 2023, 05:33:40 PM: Very difficult as the carpet goes under all the trim.

Why?

Maybe Travis found this on his side windows?

This will be a lot easier than taking all the carpet out. Moreover probably also much more effective:

Post by: Marco1979 on January 30, 2023, 06:16:41 PM: There are basically 2 options for sound proofing: adding absorption material anywhere you like, as this enhances reverberation and lowers the sound level. However, option 2 is much more effective: finding the source of the sound and adding mass and/or absorption locally.
It can be difficult to locate it, since there are so many circumstances and you cannot place your ears or a microphone near all surfaces while driving.

That said: I saw a YouTube video once where someone completely stripped his car for it. This will give you the best result, but whether it will be 2 or maybe 4 dB I don’t know.

Why?
Because there is a lot of road noise and tyre noise, and the so called carpet that they fit in the jazz is next to useless.

Post by: Wivenhoe on January 30, 2023, 09:11:16 PM: Not sure what level of carpeting you expect on a reasonably priced car. The carpets and sound insulation on my Range Rover Velar are superior to our Jazz but as it cost £ 50k more it should be.
Title: Re: soundproofing
Post by: Travis on January 31, 2023, 09:15:04 AM: Carpet would be nice and not cardboard
Title: Re: soundproofing
Post by: SebastianTR on January 31, 2023, 10:21:21 AM: For a good insulation you have to tear down the car. Like that dude on instagram.
But it's risky. Too many screws, plastic connections etc. Maybe you will get rid of road sound but you will have annoying trim sound very soon.

And I believe Jazz Mk4 is very quiet cars. After our Seat leon & arona experienced
Title: Re: soundproofing
Post by: Nicksey on January 31, 2023, 10:34:03 AM: You must have acute super extra sensory hearing if you are contemplating extra sound proofing! I found the Jazz to be quiet and road noise minimal, certainly no worse than all the Renaults I owned previously. Having also travelled regularly in a friends Merc CL, I would have been upset about the road noise he experiences considering the cost he paid.
Title: Re: soundproofing
Post by: Karoq on January 31, 2023, 11:23:15 AM: I found the e:HEV HR-V very noisy, one reason I got rid of it and went to CR-V e:HEV, much quieter.
I think the problem is that the Japanese roads are far better than those in the u.K. (couldn't be much worse! :'()
Therefore they don't need it and don't consider other markets.

Post by: aphybrid on January 31, 2023, 11:43:02 AM: I cannot understand why so many negative responses to a simple query.

If someone finds the car noisy then be positive and help or say nothing!!
Title: Re: soundproofing
Post by: Kenneve on January 31, 2023, 11:53:35 AM: I think I must be driving a very different MK4 Ex e-HEV to some of our members.
This car is without doubt the quietest of the 5 Jazz cars that I have owned.
Yes, you can hear the engine, when pushed hard, but only because it is so quiet otherwise and certainly no more than any similar car of this class, ( or indeed any manual car, when driven in the same manner)
Title: Re: soundproofing
Post by: shufty on January 31, 2023, 11:54:22 AM: ...Well I would think that if the noise levels were that intrusive, as would've been discovered on the test drive/s, then most people wouldn't have bought the car ???
Not decide to buy it then rip it apart to put some soundproofing in ? ::)
Title: Re: soundproofing
Post by: Kremmen on January 31, 2023, 12:10:46 PM: The only unusual noise I've ever noticed is in the rain when driving close to motorway roadworks barriers. It sounds like there is a pseudo hole in the lower B pillar area between the 2 nearside doors that lets sound in that bounces off the solid barrier.

No rain, no solid barrier, no problem.

Thank you you said what I was thinking.
Title: Re: soundproofing
Post by: Lord Voltermore on January 31, 2023, 08:02:03 PM: Luxury carpet is heavy ,reducing mpg . You could try quality floor mats to see if that helps noise or some noise insulation laid under cheap mats as an experiment.not a proper job but I suspect anything that would make a meaningful difference would be a major dismantling job disturbing wiring..not one I would do on a car still under warranty.
Title: Re: soundproofing
Post by: Lincolnshire Rambler on January 31, 2023, 08:21:52 PM: In my Jazz it’s the tyres that make a lot of noise. Driving onto a smooth “polished” tarmac road it’s very quiet compared to a road with a rougher surface . Maybe the blue earth tyres are the cause but on my 15 “ alloys on the SR model affects it too? My previous Nissan Note had 16 alloys with 185 /55 and on Michelin Premacy 4 tyres the tyre noise was much less. In my younger days you could notice the difference if you put soundproofing into your escort or mini.. winter driving was a real adventure even trying to get the engine to start…. The Jazz is on a different planet in comparison to those cars !!
Title: Re: soundproofing
Post by: Nicksey on February 01, 2023, 03:15:21 PM: Incidentally, what carpets are fitted to your vehicle?

When I ordered my EX Style, I was given the option of mats. The ones I went for are pretty dense, with a brushed wool like texture. One thing that did surprise me though, was the mats use a plastic twist key affair to hold them in position. I have never owned a car that has had this system previously.
Title: Re: soundproofing
Post by: Jazzik on February 01, 2023, 03:26:00 PM: Our previous car, Toyota Yaris, also had these keys, but only on the driver's side, the Jazz on both sides. It prevents the mat from sliding under the pedals.

..but this stops you using after market mats, unless you don't mind having bumps under the front edges.

This was done by Honda as I think they were sued for an enormous amount of money - in the US - of course because of an accident caused by slipping mats

It was Toyota that was sued https://www.motorauthority.com/news/1052870_toyota-to-pay-10-million-in-crash-settlement-mats-still-to-blame . I had the problem occur to me while driving a Mercedes on the motorway. Accelerator jammed, had to use brakes to control speed and get onto hard shoulder and cut ignition a pretty scary situation.
Title: Re: soundproofing
Post by: Lord Voltermore on February 02, 2023, 11:11:44 AM: My mats are genuine Honda with part numbers. Unopened . I got them on ebay for under £50 from someone who had about 3 unopened sets to sell , rather than a known Honda spares source. (maybe he has good contacts at a dealership ;) )

Full Honda logos inc on packaging but they are actually made in the,Netherlands . quite possibly by the same company shown by Jazzik. I have no reason to doubt they are Honda original equipment for the European market ,

They are quite plush but not exactly the luxury deep pile wool carpet the aristocracy might have expected on their Rolls Royces in the 1930's. They came with 2 spare clips/turnbuckles that can be fitted into the passenger side floor carpet so the mats be secured the same way as the drivers side - if you want. I didnt bother. I think you can buy the clips separately from Honda but IIRC they are about £9 just for clips.
I suspect if you avoid budget options a specialist maker will be just as good as Honda but might not include clips. If you need them.

TBH I cant say I noticed any difference in noise level after fitting the mats (fronts and rears) or indeed some rubber matting on the boot floor. But I am happy enough with the noise and refinement level any way.
I Travelled in my Daughters reasonably new Stop /start Fiesta yesterday and realised just how quieter and more refined the jazz is and without all that engine stop start kerfuffle at traffic lights etc.
