Sorry, I can't hear it from here.
Therefore, I can't tell if it's coming from under the hood or inside the cabin. I can't even see from here if you have a moonroof or a V8 or V6. I also can't tell from here if the sound changes with engine speed or car speed, or blower speed. Nor can I tell if it makes the sound while stopped or not, or while the AC is on or off, or the seats on or off, or...
In short, you're the one in the position to be able to determine the origin of the sound and you haven't provided enough information to even be able to throw suggestions out.
