How deep can you sing to be heard? Singer Tim Storms' voice is the deepest of any human being and can only be heard by elephants.
American singer Tim Storms holds the world record for the lowest voice and can hit notes so low that only animals as massive as elephants are able to hear them, the Daily Mail reported.
Storms can reach notes as low as 0.189 Hz, eight octaves below the lowest G on a piano. "I can feel them though," Tim was quoted as saying by CNN.
"I kind of hear them in my head as far as the sound my vocal chords are making but, as far as the frequencies, it's something more or less that I feel."
Storms holds the world record for the lowest note produced by a human and also has the widest vocal range, with the ability to hit notes across 10 octaves.
The singer learnt the biology behind his record breaking voice when he came across an ear, nose and throat specialist at a concert.
"He said that my vocal chords were about twice as long as normal - than he's used to seeing anyway - and the arytenoid muscles around my vocal chords, they had a lot more movement to them," Storms said.
Recently he was picked out by an international talent search for a ground breaking choral piece dubbed Tranquillity, which called for a singer to hit a low E, almost unprecedented even in classical music.
