Hissing/high pitch noise coming from the engine bay and gets louder when accelerating

[DLS_0]

Hi, I am the new owner of a 2012 Genesis 3.8 with about 42k miles on it. I've been driving it for a few weeks now and today I noticed a hissing/high pitch noise while driving (with the windows closed). The noise is audible but low when idling and increases as I accelerate.

I will look into it this weekend but in the meanwhile I would greatly appreciate if you guys/gals had any pointers for me.

It might be useful to point out that my car idles at 500-600rpm when warm.

Thanks for the help!

Have someone slowly increase the rpm while you listen under the hood.

Could be a leak at exhaust connection, alternator bearing going, etc.

If it's coming from your speakers, do you have an aux port plugged in? The aux port gives off a little bit of electricial static , sounds like a hissing noise, and the noise gets higher pitched due to the alternator spinning faster as your RPMs increase. Unplug the port and see if it goes away.
