Title: Motor way noise
Post by: Jazz03 on September 14, 2020, 12:18:56 PM
hi everyone

Wondering if anyone experienced motor way cabin noise and pressure. Feels like I'm in airplane about to take off.

I just got 2017 jazz exnavi and the noise is unbearable. I measured it using an app in my phone cane to 85 decibels

Is it a common issue. ? Car is done only 14000 miles.

Tried to lock and unlock the ac vent but still the same issue.

Current tyres are 3 dunlop sp sport 2030  and one is hankook they all look new.

Thanks

Are you sure all the windows are fully closed?  I find mine is quite a reasonable noise level at 65 mph; the noise is mainly from the tyres and varies a lot with the road surface.

Post by: Jazz03 on September 14, 2020, 03:22:06 PM
Yes they are fully closed. Im thinking to replace the tyres.

I recently got a CVT and on the Open Road they rev at such low revs that the road noise becomes a lot more apparent because there's virtually no engine or transmission noise to mask it.

I have actually just replaced all my tyres with Goodyear Efficient Grip and I thought I had been sold duds because of the relative road noise compared to my previous Honda CRV, then I realised what I posted in the previous paragraph.

Virtually the only noise audible in my Mk1 Jazz is tyre noise. Even at motorway speed, the engine is barely audible, but the tyre noise varies dramatically with different road surfaces. They have recently resurfaced sections of the A92 near me with an almost silent road surface. It is wonderful.

sometimes the road surface can make even the mitchelin tires sound like an old mini gearbox whine and then on other surfaces it is quieter

Its just crazy noisy feels pressure in my ears like airplane landing particularly in bad roads. Miss my old jazz  2003 no noise whatsoever

Feels like cabin pressure will have to sort it ASAP 
Title: Re: Motor way noise
Post by: monkeydave on September 14, 2020, 07:29:37 PM
also the doors sometime make noise near the top when the car flexes and moves the rubber seals about, usually after the car has been left for a few days outside and it goes away after a while

I canít believe you are showing a reading of 85Db, that is loud! In fact it is the legal limit for noise in a factory environment.
Are you sure your Device is reading correctly?
I have a sound level meter and will check out my Mk3 CVT within the next couple days and report back.

Regarding the air pressure, are you sure the vents at rear of the car (I think behind the rear bumper) are not blocked, which would result in pressure build up?

Thank you so much yes I used my mobile phone. I will check that vent. Didn't know there is vent at rear.

Looking forward to hearing your reading.

How do u unlock the rear vent ?

Thank you

Not sure of the exact design, but it is normally a small grill in the bodywork  both sides, with possibly a one way valve, which allows air out, but stops dirt etc coming in.
This allows the pressure build up from the air con or blower, to dissipate back to atmosphere.

This all sounds very strange. Like most small cars, the Jazz is noisy at speed because of the limited space available to fit sound-deadening, itís mostly tyre and wind noise, but itís tolerable and nothing like the OP describes. Certainly a 2017 model shouldnít be radically worse than a 2003 car.

Are you absolutely certain that one of the windows isnít open slightly? On some cars you can get an aerodynamic resonance phenomenon inside the cabin with a window open at speed. Itís exactly like blowing across the top of a bottle, or playing a flute. The result is a very strong pulsating pressure inside which can be loud and physically uncomfortable. Solution is to close the window, even moving it up or down a few cm can change the noise, or opening a second window sometimes disrupts the resonance.
Title: Re: Motor way noise
Post by: Muldoon on September 15, 2020, 09:09:39 AM
I would agree with Colin, check all 4 windows are fully closed. It may be a very small gap can make a loud noise as your speed increases.

When I got a Mk 3 loaner while my Mk 1 was having the airbags replaced, I was delighted by how much quieter than the Mk 1 it was.
Jazz03: Was it okay on the test drive?
Title: Re: Motor way noise
Post by: Jazz03 on September 15, 2020, 10:04:13 AM
In the test drive i drove it with radio on and locally not on motorway. Just spoke with dealer they will book it to get it checked. Otherwise if I decide to return the car I am loose 1500 pounds. Or I may have option to exchange within 30 days only if there is mechanical fault.

Will see hoe it gos. But yes surly my 03 jazz so quite no pressure inside cabin. I will try to upload the recording of the noise so you guys can tell.
Title: Re: Motor way noise
Post by: Jazz03 on September 15, 2020, 10:10:05 AM
Hi

Please see audio aound of noise inside the car.

https://easyupload.io/2xoawm

Let me know what you guys think

Thank you. I moved the phone back while driving by rear seat where noise is louder then front. It measured 80 to 95 decibels
Title: Re: Motor way noise
Post by: Kenneve on September 15, 2020, 11:29:46 AM
Very difficult to assess in home environment on computer speakers, but yes the lower frequencies seem to be much louder. 95Db would be like having a rock band playing in the car!!

However i've been out this morning and can give you the following figures

Mk3 CVT Tyres Dunlop 2030, Aircon On, fan running on 3rd notch. Location M42

Sound meter lying on front passenger seat & set to fast response Dba Scale
In car stationary engine ticking over:-  46-48 Dba
At 30 MPH   56-58 Dba
At 50 MPH   60-62 Dba
At 60 MPH   62-64 Dba
At 70 MPH   68-70 Dba

It's apparent that the major source of noise is road/tyre noise, where when coming back home over some local roads, the 30MPH result could be significantly higher.
Conversely, increasing the speed makes little difference.
The noise from car itself appears insignificant.

So I guess there is something definitely wrong with your car which needs looking at.
Can you hold a conversation in the car without raising your voice?
Hope this helps
Title: Re: Motor way noise
Post by: Jazz03 on September 15, 2020, 11:36:00 AM
Thank you ever so much. I can have conversation but not comfortably i have to slightly raise my voice.

I also checked my reading at rear seat which is louder noise compared to front.

Still waiting for dealer to give me a date to check it.

May I ask what tyre brand size you're using.

Again can't thank you enough appreciate your help in this

Same as mine i think I got the dunlop sp sport 2030. Maybe its something else. Perhaps I should try another jazz from dealer to see if there is a difference
Title: Re: Motor way noise
Post by: Happyarry on September 15, 2020, 12:32:03 PM
Haven't collected mine yet but on the test drive I drove a fast dual carriageway which has a ribbed concrete surface. This road is so bad, neighbouring houses had to be insulated against the constant drone of traffic.

Having driven this road in many cars over the years and been deafened in the process, I can honestly say the Jazz rode it as quiet and smoothly as any.

Coming back from Yorkshire yesterday we drove over some of that concrete carriageway (A1M or a bit of the M1 I think) and the road noise was horrendous but that is the same for most cars.

This is my second Mk3 - the first one had Michelin Energy Savers and this one has the Dunlop SP2030s. The Michelins are definitely quieter but not to the degree that would explain your issues. There must be something else going on here as others have suggested.
Title: Re: Motor way noise

KENNEVE thank you. Yes I will do that today and report back.

I am also going to the dealer to try another jazz to see if its different to mine with regards to the noise.

Thank you

If the tyres are directional, maybe check on the sidewall that the direction of rotation is correct, in case the wheels have been swapped from one side to the other.
Title: Re: Motor way noise

Title: Re: Motor way noise
Post by: Muldoon on September 15, 2020, 02:23:45 PM
The main source for most cars is road noise / roar from the tyres particularly as speed increases and on some concrete road surfaces it's very bad. If you dismiss the tyres as they look fine and most cars have this problem to a degree depending on tyre type. It could be gaps letting noise into the cabin, perhaps a panel which isn't fitted properly - possible accident damage not repaired properly? If the bonnet or door is not fitted correctly it could cause a resonance above certain speeds like a buffeting / wind noise you describe. If sound deadening material has been left out it would also make a big difference.
Title: Re: Motor way noise
Post by: Jazz03 on September 15, 2020, 04:21:04 PM
At the dealer tried another jazz and its the same. Unbearable noise. Not sure if it because the low profile alloy wheels 16. As my previous 2003 jazz was wonderful with regards to noise.

Discussing my options with dealer not sure if I should exchange it for something else.
Title: Re: Motor way noise
Post by: Kenneve on September 15, 2020, 04:22:00 PM
I went out in the again this afternoon.
Got into the car on my drive, outside temp, 29c inside temp 42c
The air con immediately went up to maximum cooling and the noise meter read 71Dba with the engine ticking over.

So based upon the previous noise results, I was effectively doing 70MPH whilst standing still ???

Slightly off topic, but with the temp conditions mentioned, what should be the temp of the air coming out the high level vents ?
I registered an minimum of 9.9c Is this normal?

At 29 deg ambient With fan on maximum 10deg is about right,  as you slow the fan speed down the air coming out of vents gets colder and can get down to 5deg.   With fan on medium speed 7deg  is pretty normal.  It is all down to the capacity of the system - with high airflow it is asking a lot to get really cold air, but 19deg below ambient is not too bad.

Post by: springswood on September 16, 2020, 08:53:32 AM
I'm puzzled because the Mk3 CVT hire car I drove in on the M62 was much quieter than my Mk1.

A leaking door seal or blocked vent should be easy to check, try opening a window on both sides of the car, an inch or so should do, and if the noise reduces then it's likely your problem's there somewhere.

Good luck.
Title: Re: Motor way noise

I had a Mark 2 and, although there is not much in it, the Mk3 is quieter.

If the tyres are directional, maybe check on the sidewall that the direction of rotation is correct, in case the wheels have been swapped from one side to the other.
Make sure the directional marks are facing forward or if it says inside or outside on the sidewall that they are on the correct orientation.

Post by: Jazzmeister on September 16, 2020, 01:22:29 PM
Op if the other ones are about the same in terms of noise then it may just be in your head, I know each time I get a new car I become hyper sensitive to every noise and nuance and it takes a month or 3 till my OCD calms down.

I'd ask a few people who's judgement you trust to come with you inthe vehicle or just to take it for a drive themselves and see what they report back in terms of the noise.
Title: Re: Motor way noise

When the OEM tyres ( Pirelli Cinturato ) on my first Civic wore out and I replaced them with Michelin I really thought I had gone deaf - the difference in road noise was unbelievable.

There are also vents in the boot to let cabin pressure out ( when the fan is running it is blowing pressurised air into car ) make sure these are not blocked by anything. The Americans call them trunk vents,  they are there to equalize cabin pressure due to fan and also when you close doors or tailgate ( to stop the windows popping out LOL ).  Normally behind the bumper moulding.

Post by: Jazz03 on September 16, 2020, 04:06:19 PM
Thank you everone for your input. I am very gratful for your help.

Yes I got 2 people in the car one reported noise is ok there but it is not too bad. The other said it is too noisy and that he would have returned the car straight away.

Dealer offered to add extra insulation by removing door panels but said its 50 50 chance of improvement.

I checked the vent air in/out but bit of difference feels when i let air in feels better with regards to pressure.
can hear the wind from the driver door. not too bad but can hear it clear.

I spoke with a friend today first thing he said TYRES then said check tyre pressure so OEM advise 2.3 bar at rear tyres and 2.2 front ones. when checked found rear over 2.5 bar and front over 2.4 so deflate these slighlty and will drive it in a bit and see how it feels and update you.

My brother said to me that I didn't hear noise in my old jazz because the wheel size was narrower i.e. 14 therefore high profile i.e. more tyre thickness between wheel and ground. My other brother suggested fitting 205 tyres instead of 185 wider and will feel soft on roads. I know one says narrowr better for noise other wider better for comfort.

I am not sure was really thinking to return it and get S Class Mercedes

but first I will try it after letting some air out and see if it makes a difference.

will update you here asap.

thanks again

Thanks for the update. One thing it might be the driver's door not sealing fully - this has come up before on the MK3 Jazz. Even a slight gap between the door frame and rubber seal would let wind noise / whistling sound come in.

Re tyres - yes a higher profile would help with comfort, perhaps less noise but it does depend on the make of tyre a lot. Difficult and expensive to experiment swapping wheels and sizes. It may be the tyres fitted are a hard compound and they generate more noise than other makes. Reducing the pressures would improve ride quality slightly and make a softer ride.

From what you say it does seem the noise is coming from the road / tyres - rather than wind or engine / gearbox noise.
Title: Re: Motor way noise
Post by: Jazz03 on September 16, 2020, 07:43:41 PM
Guys you might be surprised. I spoke with a friend of mine first thing he said Tyres so said check the pressure before replacing tyres. So the pressure recommendation for rear 2.3 bar when checked it was over 2.5 bar.  Front should be 2 2 bar was over 2.3.

So we let some air just over 2 bar and SURPRISE it is a different car. So smooth and so different n quieter. 

But then air pressure sensor poped up in dash so went and inflate tyres as per recommendation and the Noise is back terrible.

Now will repeat experiment tomorrow with dB meter. If found its tyres for sure I'll keep it n replace tyres.

Tyre date is week 27 2017. So 3 years old and done 14000 miles. My friend said it could be hard due to age and low mileage

So will see and update you

You never test drive a car with the radio on. Check it works then switch it off. You want to hear every creak, groan, rattle and knock. And if the seller puts the radio on, be very suspicious.

I used a sound meter on my 40 mile run home from the south of Edinburgh today. The average for the hour journey was 68dB with a peak of 89dB. This was with conversation in the car, the satnav rambling on and doors being opened and closed.
On my return, I measured sound levels with the engine running and the car stationary. At tick-over it registered 44dB and at 3,000 rpm it went up to 53dB

Sounds interesting, maybe stick to those lower pressures for a while. The pressure sensor system is well known for being over sensitive so donít worry, so long as you keep an eye on the tyres regularly each week you can spot any issues quickly.

If the noise changed that much with lower pressures it must be a tyre/road noise thing, I'd definitely try a new set of tyres before taking the vehicle back. It's worth it, considering the financial loss that returning the vehicle may entail vs a new set of tyres.

Especially if the vehicle still has the factory tyres it was sold with when new, often those are all season tyres or something else that is a compromise to suit the many markets and conditions a vehicle may be sold into.

The Good Year efficient grip Performance(there is a cheaper budget version which isn't as good) that I recently got are nice and got almost universally good reviews when I looked online, one of their attributes is low road noise.

Could you not just lower the tyre pressures again to what they were when it went quiet and re calibrate the pressure monitor, or is that being over simplistic?

I think youíre quite right.  The system would need recalibration after the pressures were lowered, but it should be possible to do that at any preferred set of pressures.  The system reacts to pressure change to alert you to a puncture.

It could be one tyre that is at fault. When I first got my Volvo S40 it was very noisy. I discovered that one of the tyres had a twist to it. Must have been in the steel belts. Tyre fitter spotted it right away, I replaced it and had no further noise problems.
I run my Jazz with elevated tyre pressures, front and back, and it is no noisier than at recommended pressures, just a little firmer ride.

As others have hinted, after adjusting the tyre pressures you need to tell the system to recalibrate.

Also, that Hankook tyre might be part of the problem. Google for "Hankook tyre noise".

In this day and age I cannot think why makers fit noisy tyres as original equipment ( although it probably comes down to a few pence on the cost ) - many a potential buyer has been put off by a road test that mentions road noise,  and it is so easy to avoid - plenty of quiet tyres out there.  My brother had a 8th Gen Civic and his one and only complaint was road noise,  fitted different tyres and it was a different car.

Update: returned the car to dealer yesterday. Wrote a letter to manager asking for full refund as I only been in the car for few hours and it's unreasonable to deduct £1000

Will see what happens today. For me if it was noise only I could live with it but pressure felt it in my ears.

I bought a car as my old 2003 jazz leaking from everywhere and beyond economical repair.

Will check for another car . Now thinking luxes audi or mercedes

This debate had me looking at the "official" ratings on a number of tyres. I just wonder how reliable these ratings actually are. The Dunlop 2030s have a similar decibel rating to Michelin Energy Savers but the latter are a significantl amount quieter from my own experience.

Some of the cheap "budget" ditchfinders have high ratings for performance in the wet and dry but actual tyre tests done by various consumer and motoring organisations show many of them to be almost dangerous.

Is this a case of "self certification"? If so, it's a disgrace.

Just had my Civic in for MOT and service and was lent a Mk3 Jazz as a loan car, on leaving the garage I am straight on to a national speed limit dual carriageway for ten miles I increased speed to 70 mph and more or less immediately thought I could not live with the noise for any length of time, I am not sure whether it was tyre or  engine noise or both combined but it rather extinguished any possibility of going back to a jazz after the Civic.

Edit :-  This Civic now been part exchanged for a 2020 Civic EX. :)

Just had my Civic in for MOT and service and was lent a Mk3 Jazz as a loan car, on leaving the garage I am straight on to a national speed limit dual carriageway for ten miles I increased speed to 70 mph and more or less immediately thought I could not live with the noise for any length of time, I am not sure whether it was tyre or  engine noise or both combined but it rather extinguished any possibility of going back to a jazz after the Civic.

Exactly that is my point. Can imagine driving the car for 6 hours drive from London to somewhere up north !

Did it feel like airplane taking off landing ? Did you feel pressure in your ears as well?

Thanks

This debate had me looking at the "official" ratings on a number of tyres. I just wonder how reliable these ratings actually are. The Dunlop 2030s have a similar decibel rating to Michelin Energy Savers but the latter are a significantl amount quieter from my own experience.

Some of the cheap "budget" ditchfinders have high ratings for performance in the wet and dry but actual tyre tests done by various consumer and motoring organisations show many of them to be almost dangerous.

Is this a case of "self certification"? If so, it's a disgrace.

I agree with you 💯. The rating means nothing. Its  a shame though

Funnily enough the noise rating is for people outside the car, not inside.  Road surface makes such a huge difference to noise level,  I wonder if they have a 'standard' road surface to test the tyres ?

Yes, the reference surface for the tyre certification noise test shall be according to ISO 10844.

There must be something different about the car compared to mine.  In the last fortnight I have driven from Suffolk to Newcastle-upon-Tyne and back, and I am now in Cumbria.  Good quiet journeys all the time on motorways and dual carriageways.
