At TED2011, Physicist Janna Levin spoke about the sound of black holes:
Black holes can bang on space…like mallets on a drum, and they have a very characteristic song.
Black holes can be heard if not seen.
These black holes will ring in a frequency that your ears can hear. You head would be squeezed and stretched [so you might have difficulty hearing them.]
Imagine a lighter black hole falling into a heavy black hole…We can predict what that sound will be…We know that as it [the smaller black hole] falls in [to another black hole] it gets faster and louder and eventually we will hear the little guy fall into the bigger guy. [Levin plays a recording that vaguely resembles a heart beat, which then speeds up to what sounds like a basketball dribbling on a court. Levin notes it “chirps up at the end”].](http://27.media.tumblr.com/tumblr_lhfxymrHK31qb8ulho1_500.jpg)
