High Frequency Ringing

Engine or alternator whine would change pitch with the RPMs. As you accelerate and your RPMs go up does the pitch of the whine go up as well? If it is at a constant frequency then it is something else.

engine whine... you usually only get it, if at all when you install aftermarket equipment. and like someone said above its feedback into the audio. usually it happens when RCAs are ran next to power wires . however does anyone know if infiniti uses fiberoptics or feed through the car digitally? ie MBs and BMWs, etc... im very surprised to see this from a factory equipped stereo. i wouldnt know what else to suggest other then the dealership. ill ask one of my technicians at work tomorrow and try to report back with some possitive info.

I've got it too. Good to hear im not the only one and im not going crazy and hearing things. It's a very light high pitched buzz from the right side of the car. It comes and goes at random times. Radio climate control etc. on or off it doesn't matter. If you go to the dealership have some younger guys listen in. Its like that high pitched sound older people cant hear. It really just depends on the persons hearing thought.

That certainly doesn't sound like alternator noise caused by a ground issue.
Does it sound kinda like the noise a laptop will make sometimes? Intermittent and high pitch? I am wondering if it is the car's computer (or one of the pieces of it).
Does it come from the speakers? Or is it coming from inside the dash?

I can't tell exactly where it's coming from but it's not from the speakers becasue it happens with audio off as well. I've never been able to decipher if it's from the right side of the car or not. Wakeboardr116 is right though, it is quite high pitched and many adults might not hear it. I'm not exactly young, and I can barely hear it. Has anyone else ever turned off the stereo, climate control, rolled up the windows and listened for it at atound 80 MPH? Maybe it's in everyone's car and they just haven't noticed? Or perhaps it's just some of us and something's wrong.

It really doesn't matter if the audio is "on" or "off". The Bose amplifier is give the 12V "on" signal if the car is in the on position. Whether or not it is the radio I don't know obviously. Just letting you know that the amp is on regardless of whether the radio says "Audio Off".

I would go easy then hard. Start with parts on the outside of the car to see if something is being exposed at higher airflow rates. try to have someone else in the car poke around and listen for a source, while going 80+. high frequencies can be a b$tch to find sometimes.
