Fun facts: you may actually hear an orbiting black-hole spin if you're close enough. It's possible for gravitational waves to reach the same amplitude as sound waves, which would probably cause your eardrum to activate as space contracts and expands past it, so you would "hear" something, but we don't really know what it would sound like, likely a hum or high-pitched thrumming.

Depending on the size of the black hole (smaller is more likely for this) you may also "see" static in the air, as hawking radiation is emitted by the space around the event horizon. Hawking radiation doesn't come "out" of a black hole, that would be impossible. Instead, it "appears" in space around the black hole, and as it does, it draws mass off the black hole. For larger black holes this area of hawking radiation could be enormous, millions and millions of miles, and it would be very, very faint. For smaller ones, it may actually throw so much hawking radiation out that it would appear in your retinas at times.
