Cabin Noise

Cabin Noise

I have now test driven the Model S Performance twice and haven't been impressed with the cabin noise at freeway speeds (70-80). Once you hit 60+ I was noticing a wine from the gearbox that gets really noisy at 80 (definitely, not the invert sound). There was also a surprising amount of road noise from the wheels in the rear. About on par with my Z4, which I found noisy. Our X5 and M5 (full leather which helps) are about twice as quiet at a similar speed (and trust me the M5 has much noisier tires than the Model S).

This similar with other's experience? Has me considering the vehicle or if to plan on an audio shop adding sound dampening... Just really surprised me as if it was me I would have made sure to have "owned" quiet if producing the vehicle. At lower speeds it's amazingly quiet just by being an EV before the road noise kicks in.

I haven't driven a performance version, and the 21" tires might make a difference as well, but I found the road noise was quieter than any other car I have driven at highway speeds -- however, it was more noticeable because you didn't have engine noise to hide the road/wind noise. Are you sure that isn't what you are experiencing?

suegie | 26. desember 2012

I always have my radio on, but I find it to be quite quiet. Honestly, I am enjoying the drive so much, I really don't care if there is a little noise! But, when I open the roof and drive it really sounds loud, not sure the deflector is doing its job.

lph | 26. desember 2012

Was the test car a production model or a beta version?

Carefree | 27. desember 2012

I don't have my MS yet but I can imagine that in an otherwise quiet car (eg no engine noise) cabin noise at highway speeds might appear much higher. You should measure it. You might be surprised.

dtich | 27. desember 2012

the car is really quiet. no two ways about it. if you think you can fly down the road at 90 mph and not hear something, well, your expectations may be off. i have had bmw's and lexus's for over a decade and this car beats them hands down. it's a joy. yes, little wind. yes, little tires. maybe even a little whine as you pump 500kW into the motor.. but you know... it's little. quiet. very. (performance, 21")

dtich | 27. desember 2012

not 500kW obviously... it's late. lol.

mrspaghetti | 27. desember 2012

I've seen others claim that so-and-so vehicle was quieter too. It would be interesting to have someone measure with a dB meter and post results. And if you could do it over the same road at the same speed with the comparison vehicle, so much the better.

adurstewitz | 27. desember 2012

@mrspaghetti - I think the point that you're elleuding to is that volume can be a matter of what we are used to hearing. I've never owned an EV before. So I'm sure ill hear the whine, at first.

Thumper | 27. desember 2012

There is a db phone app but it doesn't seem to work for me at all.

Some Roadster owners report hearing birdies tweeting while driving with the top down. Apparently they're not bothered much by it, though.

Here is my email to George Blankenship from about a month ago and the reply from TM about Active Noise Cancellation. Wind and road noise seem to be perfect candidates for this technology.

Hi George,

You’ve been very nice to read and reply to my emails, as you must get many from owners and potential owners like myself. I know the list of requested Model S software enhancements is long and that many of them are already in the works, but I’d like to add active noise cancellation to that list if possible.

Due to the lack of IC engine noise, some owners and reviewers have noted the “relative” noise of the wind/air and tires/roadway at speed. The absolute sound levels of these components are most likely the same as with any other premium car, but as you know there is no IC engine noise to drown them out.

Many car manufactures use active noise cancellation technology already: http://www.usatoday.com/story/money/cars/driveon/2012/09/26/cars-noise-c... and Bose will license their technology: http://editorial.autos.msn.com/blogs/autosblogpost.aspx?post=a5b6fb48-36... . The Model S already has a microphone to sample the ambient noise, and of course the necessary speakers, so I think this is a software-only fix/feature.

Since I know that everyone wants something (or more) for “nothing”, I tend to suggest things that are “win-win” for the buyer and Tesla Motors. Why not make this a feature that you get with the Sound Studio Package? That might drive up the adoption rate of that option enough to offset the Bose licensing fee, or you could just add their per-car fee into the SSP cost. Either way it’s a feature that many people would desire (and pay for) and it could increase the per-vehicle profit without a change to the car’s hardware. You could add “quieter than a Rolls Royce” to the list of Model S accolades!

Finally, congratulations on the Motor Trend Car of the Year award! What an achievement for such a young company.

Here's the reply:

George Blankenship forwarded your email to me. Thanks for your support and suggestion.

I agree that noise cancellation technology would be a nice addition to Model S so I forwarded your note to our infotainment team. One of the things we really like about the Sound Studio package is the value derived by engineering the system ourselves and avoiding licensing fees. But as you say, perhaps the sound improvement could warrant the added costs.

Thanks again, and Happy Thanksgiving.
Ted

Both Motor Trend and Inside line have already done noise checks. Both tests indicate state of the art quietness as far as the tests go. I don't remember what dB scale they used which could skew the results if dBA were used.
With the inside line check it came in LOWER than the Bentley BMW M5 and all the other tests I could find at 70mph and blows them away at slower speeds and acceleration.
Perceived sound is a strange thing. Humans pick up on certain types of sounds more than others even though the pressure is the same.
However, as Getting Amped Soon indicated a noise canceling system would not be out of the question for Tesla and may be desirable.

DTsea | 27. desember 2012

dtich, 400HP = 300kW (1HP=746W). That's still a lot!

sergiyz | 27. desember 2012

I had a lot of cabin noise at over 50mph until Tesla adjusted the window on the passenger side.
I bet they will have to do it periodically since the windows are frameless and move up and down every time you open a door.
You can do a visual check and spot it fairly easily: look from behind and pay a close attention on how the windows align with the door frame and the roof.
I was able to see it sticking out a bit.
The adjustment was easy, they were done within 15 mins or so.

RAFellows | 27. desember 2012

I test drove a production performance model in Seattle (Bellevue store) last month. City streets and two sprints to 70 on the freeway. I was sitting in back for 1/2 of the trip. It was extremly quiet and I did not hear any whine from the motor. I found a site that has a full list of car sound levels at various speeds. I don't know how accurate it is, however it does list the Model S. It can be found here http://www.auto-decibel-db.com/

fluxemag | 27. desember 2012

I'll bet it wasn't the "gearbox"...

portia | 27. desember 2012

I have a performance S and it is really quiet at freeway speed, 70-90 even, and if you hear a lot of noise it might be something wrong with that particular car.
road noise from the tires depends on the road surface, good roads are really quiet. I would say the Tesla is one of the quietest cars I have driven (Mercedes Benz and Lexus GS among them)

KevinR.co.us | 27. desember 2012

Tesla Model S "Hybrid"?? -- I 2nd Fluxemag not likely the "gearbox"

gocken1 | 27. desember 2012

That list can't be right for the Model S. It says the Model S idle is 35.6. That's 15th on the list. The only sounds we should hear at idle are external.

Superliner | 27. desember 2012

@gocken1

It also says Tesla Model S "Hybrid" which is of course not the case. Idle would be akin to sitting still in a luxury ICE with the engine shut off lol!!

lph | 27. desember 2012

Next time they test the MS they should tell the birds to be quiet.

jat | 27. desember 2012

There are sounds for the battery cooling system when "idle", the same as the LEAF, but I agree that sounds suspect and is more likely external ambient noise (I doubt they put the cars in a sound chamber for the measurement) or maybe they had the HVAC on.

Regarding "gearbox" - there is still a differential, which could be considered a gearbox.

garyrudolph | 27. desember 2012

It was a production car and not a beta. Although, perhaps an early production differs.

It's funny, I forgot to bring my dB meter with me (seriously meant to). I'm going with a friend on their test drive next week, so I'll bring it with me then. At least that will help me figure out if it's all in my head with decreased engine noise or not. Bit, frankly dB meter tests aren't consistent unless on the same road, etc. as the road surface vary so much in SoCal which affects the road noise.

As for the gearbox... Tesla isn't running a 1:1 from the motors to the wheels, so there certainly is a gear reduction gearbox that is part of the diff/drivetrain. And it definitely made noise at 70 when sitting in the back seat when the wife was driving.

garyrudolph | 27. desember 2012

Getting Amped Soon: You know it's funny on the sound test. I can at least verify that on that list the Dodge Ram is one of the quietest vehicles I own. Albeit, it's for towing and I don't feel like driving it all the time.

The problem is it's a little subjective as noise isn't noise to everyone... (as affirmed by all my arguments with my parents about AC/DC ;) ). Also, in the 1st test drive I didn't notice it so much, but the in the 2nd test drive I was being critical and was focusing on it as my father noticed it on the 1st test drive.

lph | 27. desember 2012

You might want to check the the decibel meter is set db-B setting. I believe this more accurately measures the effect of human perception within 55 and 85 db. DbA is better for quiter sounds and dbC for louder. Looking forward to your results!

DTsea | 27. desember 2012

Use speech interference level.... that's the most relevant. A 35 dB environment is VERY quiet. Remember the dB scale is logarithmic so a 10 dB change is LARGE.

walla2 | 27. desember 2012

I get noise from the road only when I am on dirty roads the little bits of loose gravel left over from chip sealing and such. Otherwise, the car is very quite in my opinion.

please post the tables again, but this time paste them between <pre> </pre> tags. That will preserve the fixed font spacing, though it will be a smaller font. Add <H2> </H2> tags to make the numbers bold in a larger font, preferably. Here are a couple of lines manually recreated as an example of the result:

I recommend putting the table in Google docs and providing a link. That is easy and it lets others work with a copy if they want.

No need.
When you use the link above from RAfellows (just before the lists) you can look at and minipulate not just the cars directly posted on this thread but many more. Just by tapping the title.you get data sorted by that field.

I get this sort of pressure noise at speeds > 40 in my performance model. It sort of sounds like the kind of pressure noise you get when someone's window is cracked open and you're accelerating. Anyone notice this sort of thing? I might bring it into the service center to have it checked.

@lph - Thank you. I was worried I was going to end up like the guy who created the Model S Clock - working for the Tesla forum!

Should work with a copy-paste between the tags.

Almost. The titles need adjusting to 2-line versions.

Anyhow, if you need to use tables, that's the only way to achieve fixed spacing on this forum. None of the usual tags work, and many of the "allowed" ones don't, either.

GeekGirls | 29. desember 2012

The data on the source site is presented without any information about how it was captured, and looks extraordinarily dubious. The notion that a Boxster Spyder idles at 0.8 dB is pretty laughable. It's certainly enough to cast doubt on the validity of everything else in the chart.

lph | 29. desember 2012

Yes, some of the results seem out of line particularly at idle. It could be that these are a compilation of tests from multiple testing agencies.
If true then they could be using different standards in testing. ie. dbA vs dbB or dbC scales on the meter and different environments (different road surfaces) etc. So it is prudent to view these results as a rough guide and nothing more.
If there is a data base that uses the same sound testing methods on all cars then I am all ears!

mferrazano | 02. januar 2013

mrbry83: I noticed similar "wind" noise on my Perf as if there is a window partially open (do you have a pano roof?). Did you take it in to the service center? If so, any improvement?

Getting Amped Again | 02. januar 2013

@GeekGirls, yeah that is pretty hilarious, as is the 35.6 dB reading for the Model S at idle! That had to be someone sitting in the back seat going "RRRRRRRMMMMMMMM."

Actually the takeaway for me was that the Model S at normal highway speeds was right in line with the very top premium cars, and better than almost all of them at 140 km/h. That's good enough for me.

I think that data should convince a current owner who is experiencing unexpected wind noise to have TM service look at his/her window and trim alignments, as previous posters have shown that to fix the problem.

Finally, other posters have pointed out that noise is very subjective and the lack of engine/exhaust tones may make the road and aero noise more noticeable, even though it's actually quieter overall than an ICE vehicle. I still hope they consider the active noise cancellation option, as that is understood and readily available technology. The Bose headphones work great, as do other brands.

rwang | 02. januar 2013

The whine is noticeable when i cross the 100 kw/h rev line. It's like the noise late 90 cars made when you accelerated and could pick it up on the FM stations and definitely on AM.

andex23 | 03. januar 2013

I agree with OP and rwang. I have 1200 miles on my perf S and can definitely hear some harmonic sound at freeway speeds coming from the rear passenger side of the car. The pitch changes as I accellerate which leads me to believe it is the differential. The noise is faint but I am young, my hearing is still pretty good.

The more concerning noise just recently occured. When in hard accelleration I get a high pitched tone, can't place where it is coming from. It sounds like a hearing test tone. I need to look through the manual to double check any warning tones. Both occurences were when the car was just "engaged"(can't say turned on) after sitting in the cold outside for an hour or so, maybe it is some sort of warning.

Last, I will check the windows as some have mentioned, I swear I hear excessive wind noise from the tringular fixed piece in the front doors. I expect wind noise, this just seems too pin point to be regular.

Car is still awesome, these are always minor issues, but any improvement is incredibly valuable.

dborn @nsw.au | 03. januar 2013

@andex23- Guess that is because the car is complaining about being cold! I would too! Hey, it is a California car, and it has feelings too! Wants water and surf, not ice and salt! Bring it here to Australia where it won't have to suffer!
Actually, i wonder how the car would fare in the temps we are about to experience of up to 44 degrees Centigrade!! Does anybody know if they have done REALLY hot weather testing? Above is 111deg F !!!!

Andex, call Tesla, have a service tech go for a ride with you

mferrazano - not yet, will try to go next week when I'm less busy. I'll update the thread with any findings.

Play lotsa rock etc. at 9, 10, or 11, and wear earbuds most of the day, and your 'sensitivity' will cure itself. >;)

Went for a 3rd test drive today (on a friends test drive) at a different dealer (Santa Monica)/car. This test car (around #1,200 production) didn't have the hum from the drive train, and was on par with what I expected. The road noise is about average for a similarly priced car at speed. Not the quietest I've been in, but acceptable. Most of the noise is tire noise, and depends on the road surface.

Also, the inverter was surprisingly quieter and also surprised the Tesla copilot as they noticed it quieter than their previous test car.

Unfortunately, I brought my sound meter and ended up leaving it at the office when we went for the test drive... Would have been nice to compare, but it's all subjective anyways from a "psychoacoustics" perspective.

It alleviates my fears, although I do wonder if it's an early production issue, or a mileage issue.

andex23 that high pitched tone on hard acceleration is the performance model inverter sound. If you let off the accelerator it should go away and if you press it hard again you'd hear it. The hum from the drivetrain was related to the speed of the car regardless of what you were doing with the accelerator.

Have you noticed it getting worse since you owned it (i.e. related to mileage)? Or do you think it's just something you didn't notice in the beginning due to just being excited with it? If you don't mind, what production number?
