Inverter Noise Insulation - anybody done it?

I hear that high pitch sound. I thought it was on the rear right side but, from what I read, it might be from under the hood? It's that continuous, high pitch, whistling like (kinda like brakes screeching but electrical and quite faint).

So I'd like to know, from the savvy ones: where is it located and has anybody successfully masked it?

PS: not sure I have this thread in the right place, could a mod check that and let me know if there's a change.

 

Probably not gonna happen Jerry ). It's a very high frequency, high pitch sound like electricity static - nobody likes that, I'm not sure we're on the same page. See the link below.

There is another sound which sounds like sci-fi, which I like a lot btw: each time I accelerate and decelerate the electric engines make the smoothest "vrrrrrr" and the brakes go "pssst". That's classic electro music.

Bisco, not sure I can record that, it's extremely subtle. But THIS right here is on the money - it's quite like that actually, and somewhere distant like a fly 3-4 feet away (1 meter ish) either in the back or idk where.

I've done a test several years ago (I had this mild tinnitus) and the sound tests at the hospital came out really good; I was told I hear very well.

 

If it was only that. I will take panels off and investigate in a few weeks.

 

It's a 2012 with about 88k miles on it. I noticed it ever since I bought it.

So, went driving, the sound comes when the big battery is charging - either breaking, or when rolling, no traction, every time the arrows indicate the battery is charging.

But I don't think the age matters. I've been reading about people noticing this in their brand new cars. I think this car was opened a bit - not sure what is its history. But when I looked underneath around the battery there was a screw missing, things were a bit loose, and Toyota told me that the battery has been disconnected upon a checkup (but they said the car was in great shape). The rear bumper is a bit too loose. Idk, I can suspect it has been in some accident and it was flipped and made look nice; idk idk idk ...

It works fine. I just want to tune it, to be blissful and that's about it. I kinda got used to it, so it's not bad, but not good. There is this other thread about the high pitch where some say it's from the inverter.

 

I edited that post while you were writing - yes it seems to be from what other say in that thread mentioned above.

It's happening when the battery is charging as far as I can see.

 

It's really fine. Most of the time I forget about it; but when it's on my nerves, it's on. And I also wonder if there isn't something wrong with it.

 

Awesome bisco! Thanks! I made this older post about very low static in my speakers each time I turned the car on. I have to stick my ears down close to a speaker to hear it. Either way I wasn't sure this was normal - though people said it is - I suspect it's related.

 

James I don't think it's a noise maker. I had my rear seats out and I had to install them recently. I don't really notice that noise. It's either something related to the head unit like Jack the Riper says or something around the battery - it sound high pitch, electrical, like an inverter or transformer.

People can't hear me coming usually.
