What’s the Sound of One Black Hole Singing?

What is the tone that a black hole makes when it sings? It's a sound so low that it will send chills up your spine. The tone, a B flat 57 octaves lower than middle C, which is 256 Hertz. Sounds as low as the black hole singing are detected as pressure waves, rather than as sounds.
