The Black Eyed Peas mastermind and television judge suffers from chronic, severe tinnitus that manifests as a constant, high-pitched ringing inside his head.

The producer revealed that the phantom noise can become mentally overwhelming, which is why he constantly surrounds himself with loud music or studio work to drown out the internal frequency.

Detailing the invisible battle, he shared: "I don't know what silence sounds like anymore. Music is the only thing that eases my mind."
