2015 Sonata Sport 2.0T Slide Whistle Sound from engine

[PTX1516]

I am getting a sound best I can describe is like a slide whistle or when you blow into a straw with one end closed. 2015 Sonata Sport 2.0T. 83,000 miles. It started about 2 weeks ago. Now its a constant. Happens when accelerating. The more pedal I give it the higher the pitch. Once I get out of it and smooths out no longer hear it.Does not matter if a/c is on or not. Does not do it when in park revving the motor or going to neutral and revving the motor. No loss in power, gas mileage has not faltered. No engine light has come on. Sound seems to be coming from the center or right side of engine compartment best i can tell. Anyone had this issue or know what could be going on. Thanks in advance.
