Take Tim Storms, for example.
He holds the Guinness World Records for lowest note produced by a man and the widest vocal range.
The video was made by Alpha Sound to get to demonstrate the quality of Sony EX15LP headphones.
He manages to achieve a frequency of 0.189 Hz.
Thats eight octaves below the lowest G on the piano.
But according to Storm, he can sing even lower than this.
He claims his lowest note can only be heard by elephants!
