Hallo I have this problem with funny noise coming from my Suburban model 2014,

What is your question?

Hallo Noise sounds like whistling. All began on 15.000 miles driven, basicly a new noise began to generate from front part of vehicle when driving around of 60 MPR and‎ is gaining on volume as speeds goes up. At spead of 90 MPH is noise so loud that it is annoying to keep on the speed and makes just to go slow to keep the noise slow.......but...this is very important....when I release a gas pedal...at hig speed... for example 70 MPR, RPM 2000, but no touching the gas padal, nose vanishes!!!! and when I just bearly just touch speed pedal without speed and RPM going up, noise generates again !!!! Some days the intenzity of the noise is lower and some days higher. But all is in common, when RPM and speed are high..... by releasing the gas padal.... noise stops!!!! by just touching the gass pedal ...here we go again...‎noise. So basicly...it has something to do with part of vehicle which is not in motion when guess pedal is released. Any ideas what might cause the whistling ?
