Lewd noise pollution do you leave or tell the offenders to dummy up?

If a course of conversation is leaked be it unintended in hear shot of you do you leave or tell them to dummy up? Say you were on the side of your house cleaning the gutters and your neighbor’s tween daughter and some of her friends enter their patio and start chatting in “cell phone voice” rather loudly. There is a line of bamboo between so they cannot see you or you them but they should have heard you since you were making quite a racket cleaning the gutters. They jump right into talking about having sex up the backdoor bareback, and which boy has the nastiest tasting spunk, to who they want to put their sights on to boink down to how to not get caught boinking in their parent’s bed while they are gone. Do you tell them you are there and can hear them because they seem to can’t hear all the noise you are making cleaning the gutters with the hope it embarrass then enough to go back inside or do you abandon the gutters and hope they leave so you can get back to the task at hand?
