How loud is a black hole in terms of its gravitational waves and the impact it has on its surrounding environment?

Darling, a black hole doesn't exactly have vocal cords to belt out a commentary on its gravitational awesomeness. However, when a black hole gets its groove on and sucks in some matter, it can whip up some serious gravitational waves that can make nearby objects tremble like a diva demanding attention. Think of it like a Beyoncé concert on steroids - always making a big entrance without saying a Word.
