Black hole hums deepest note ever detected

WASHINGTON, Sept 9 (Reuters) -- "Big black holes sing bass. One particularly monstrous black hole has probably been humming B flat for billions of years, but at a pitch no human could hear, let alone sing, astronomers said this week.

"The intensity of the sound is comparable to human speech," said Andrew Fabian of the Institute of Astronomy at Cambridge, England. But the pitch of the sound is about 57 octaves below middle C, roughly the middle of a standard piano keyboard.
