High-pitched "Electrical Whine"

[waltermorel]

This IPC buzzing noise is really intolerable and we still have NO fix !! ???

Yes - it is very annoying, and I'm sad that there still isn't a fix. Baffling to me as well that they haven't found better hardware that doesn't whine.

I've learned to live with it, but if the music ever stops it's the first thing I notice, so music while driving is basically a must for me.

The noise is 100% there and intolerable. My 17-year-old son (who drives an '06 GT) refuses to drive my MME without loud music on to drown out the buzzing because, in his words, "it is so annoying."

Maybe it's only 50% there. My 16-year-old hears lots of stuff I don't, but no Mustang buzzing.

Yep. Weirdly and sadly for an EV if there is no alternate source of sound then the “silence” is intolerable.

Well, this exists in the Lightning as well, despite being recessed in the dash and behind a transparent barrier.

WTF. Just, WTF.

I’m so sick of high frequency EV noises. Going back to gas for good after this where you can actually get true acoustic comfort. No more coil whine, dentist drill sounds, etc.

Your Mini is a worse noise maker than an EV. The difference is EVs propulsion system is so quiet you hear things that are otherwise drowned out my your ICE Engine and Mechanical drones. But still this may be preferable to some as the higher overall noise may be like "White Noise" effect and your auditory sensory system can't focus on other noises.

There may be a lack of masking effect, but it's not the primary issue here.

Here is an image of the sound in the Lightning. The horizontal lines are tonal noises just like in the Mach-e. I can hear these sounds while in motion in the Lightning. They would also stick out in a luxury ICEV that I am used to driving, such as a Lexus or Mercedes.

I recorded some ICE cars in accessory mode and heard and saw almost nothing. The EV systems (drivetrain, inverters, battery cooling, screens, etc.) are adding annoying high frequency tones even when the truck is doing nothing. You are right that tonal noises are harder to ignore than broadband noise.

Ok.

If it bothers you they much, get something else. Life’s too short.

Bye.

Most of the engineers are probably too old to hear anything above 10k, they likely have no idea how much high frequency noise is happening. Since they've never dealt with high frequency electronic noises before, I wouldn't be surprised their NVH program does nothing to detect, quantify, or address them. They should be running a spectral analysis like this during NVH testing of EVs and specify component noise thresholds to their suppliers like Visteon. And obviously run instrumented NVH spot checks on the assembled vehicles to ensure consistent quality. Display loudness really varies, you could get a quiet one or a loud one from the factory.

The worst noisemakers in Mach-E at idle are the instrument cluster and the power steering motor. The front motor in the non GT's also has gear whine around 30 MPH, Magna should have tested that better. The windshield gap is also a noisemaker on some cars if the windshield isn't placed just right, and the tempered front windows also let in a lot of side mirror wind noise. It's not horrible, but things could have been done better, as a result the Mach-E really isn't any quieter than my 13 year old Fusion.

Yep, yep, and yep. Lots of noises, exactly where you said. At this point just have to live with them.

Going to update my super old thread here with good news:

https://www.macheforum.com/site/thr...-mach-e-non-gt-buzz-noise-from-the-ipc.28524/

I've scheduled the service appointment to have this done and have my fingers crossed I'll have relief after living with it for 2 years.

Seems like I may have to wait for the software update for complete relief, but I'm happy Ford is finally addressing it.
