The singer will release Underwater as his fourth studio album in the UK on July 30.
Radin suffered a punctured eardrum as a toddler and was warned by doctors that he would experience severe pain if he ever immersed himself in water.
However, the star decided to take the plunge while writing his new record in order to gain inspiration.
"It was mind-blowingly cool," Radin explained. "Even when I'm sleeping in bed, I can hear my heartbeat.
"I never realised the silence one experiences underwater. My brain was totally free to come up with a melody line, and that's where this album began, underwater."
Radin has worked with a number of musicians for the project, including Benmont Tench, Jim Keltner (Bob Dylan, John Lennon) and string arranger Jimmie Haskell (Simon & Garfunkel).
Underwater serves as the follow-up to 2010's The Rock and the Tide.
