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.

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:

Brand Model Spec Year dB at dB at dB at dB at dB at dB at dB at idle 50kph 80kph 100kph 120kph 140kph 70mph __________________________________________________________________ Dodge Ram 5.7 V8 2010 39,2 47,5 52,6 55,3 57,8 60,3 56,1

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.

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.

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!

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?

@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.

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.

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.

@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.

"The noise is faint but I am young, my hearing is still pretty good."

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?

The high-pitched tone on hard accelleration is not just on perf. Happens on my non-perf too.

Happens on my non-pert as well and I think its getting a bit louder. I'm not really concerned yet because (a) only really noticeable when romping on the accelerator, (b) I'm grinning while doing that, and (c) I think Tesla will fix these kind of details over the next years as they find good solutions.

As others have posted the very high currents involved in inverting DC to AC can easily cause mechanical 'ringing' in inductors and possibly capacitors. I think they will eventually repair or replace some components under warranty to permanently reduce the noise to an acceptable minimum.

In the meantime my family calls this noise "going into warp drive". !!!!

I guess it is good that you hear it also but the tone was not present in the first 1100 miles,. Trust me, I gave plenty of test drives where it was full on acceleration until reason kicked back in.

Maybe the car is getting faster!

I am also hoping the parcel shelf can further reduce the drivetrain noise.

Just wanted to share my experience with wind noise. Ever since I got the car about a month ago, had noticed a fair amount of noise above ~45 mph, which seemed to be coming more from passenger side. My wife also noticed it. Wasn't sure whether it was just unavoidable noise that is normally covered up by engine noise in other cars, or if something was amiss. Couldn't find any problems with pano roof seal when I checked.

I told local service center about it, went today and took the service tech for a ride. He localized the noise to the small triangle window just in front of the main passenger window. Apparently at the factory they do a water seal test, with what he called 'monsoon' amounts of water at high pressure. This is above what most cars will see in regular conditions, so what ends up happening is a bit of overzealousness in adjusting the seals to keep out water. With my car, the emphasis on tightening the inner seal by making window sit tight to the inside, led to an air gap on the outer aspect of the window, hence wind noise.

He was able to fix it within 20 minutes. Car is very quiet now. I went through a car wash afterwards and had no problems with water leaks.

Excellent! Little flaws get fixed. Nice.
