Question Humming noise comming from intake??

Ok this is prob the 10th time ive asked this and im starting to run out of hope.
My car makes the wierdest noise while accelerating. I will describe; After ive run the car well over operating temp. When i start out of a gear as im pressing my gas at the begging point of the gas, i get this really anoying humming noise kinda like a flute or somthing. I only hear it during light throttle, it imediatly goes away once i press the gas more. And i mostly hear it in fifth gear around 50mph like at 2-3 k ALWAYS AT LOW THROTTLE.
K so my guess is that this noise is comming from my throttle plates or from somewhere in the intake system of the car.
I just would like to know if you guys have ever heard of this and if you guys have any clue what it is plus tell me how to fix it?? That would be great. Ive had this goddam noise since ive bought the car

Oh yeah one other thing
I have no cats and a single exaust all brand new, plus this noise existed before the exaust was upgraded. This is the reason i have norrowed it down to the intake system

Sounds like something is loose and rattling.

There's nothing in the intake that could cause a humming noise other then strange vacuum or air (from the airpump, ACV) leaks.
