For any of you with CTDs, have you ever noticed if someone else is driving the car and you're talking to the on the phone, there is what sounds like a turbo sound in the background if they're accelerating?

The first time I realized it, I was driving the car talking with my buddy on the phone. He asked me if I was driving a turbo car or something (he lives on the other side of the country and has never seen my car). He said he could hear the turbo spooling up and down in the background quite clearly. I told him that wasn't likely since I could rarely hear it, and most likely there must be some interference from the voltage regulator when the alternator spins up and down.

However, after he told me that I noticed that whenever my wife is driving the car and she calls me over the Bluetooth in the car, I can very clearly hear it as well. I don't see how it's possible, but it certainly sounds like a turbo spooling.

Has anyone else noticed this? I never noticed it when I had my gas Cruze.

Finally...someone else other than I has this issue.
I can't say I really thought of it as an "issue" so much as I'm just curious. I've been assuming it is something electrical, but it certainly sounds like a turbo spooling mostly because it is not consistent. As you said, only heard at low speeds when slowing/accelerating.

Being a pilot and having heard the common electrical whine produced by alternators with planes with very complex electrical equipment, I can't say this really worries me. I've never had any other gremlins (knock on wood) other than the common O2 sensor replacement.
