Just how low can a person go? Around eight octaves below the average person, if you're U.S. singer, Tim Storms. (SOUNDBITE) (English) TIM STORMS, MAN WITH WORLD'S DEEPEST VOICE, SAYING: "My lowest note would be somewhere around, if you were to take another piano and sit at the bottom on the left side of the piano, that would be about how low I can go - eight octaves lower than the lowest G on the piano." He's stormed the world records for the widest range of octaves - that's ten, and for reaching the lowest note, which can't be heard by the human ear. One doctor was compelled to find out what created Tim's extraordinary gift. (SOUNDBITE) (English) TIM STORMS, MAN WITH WORLD'S DEEPEST VOICE, SAYING: "He said that my vocal chords were almost twice as long as he's used to seeing and the arytenoid muscles around my vocal chords - they had a lot more movement to them." Tim Storms is putting his talents to use on a record he made with the composer from last year's British Royal wedding, and the St Petersburg Chamber Choir.
