Problems with Inductor Humming in a Buck Regulator

Hello everyone,

I just have a quick question. I have a Buck Regulator to drive a string of LEDs and everything seems to be in order except that the inductor is making a noise. When I increase the brightness the noise also increases, and accordingle, it also decreases when i decrease the light.

What could be the possible reason for this?
