one of my neighbour couple is too loud while making love during day or night. Their mourning and Noise of their bad hitting the common wall is irritating, embarrasing(if some friend at home).. please suggest what can i do best to stop it...
How well do you know them? If you've already spoken, you might want to address the issue, but mainly under the aspect of it robbing you of your sleep, not the embarrassment, which is frankly your problem, not theirs... For instance, could they possibly move their bed to the other wall. If you don't know them, then I suggest positioning some music device towards the offending wall and turning on something totally unsexy (if it's cool music, they may think they're having a film moment, where music starts playing in your head) at a sufficiently loud volume to drown them out.
After they're done, rush over their place in just your boxers with a bottle of lotion and a box of tissues and say "just another 10 minutes, please, I was nearly finished". I reckon they'll be quieter from then on.
Or, you could totally put them off by adding your own groans and grunts to match theirs / go against theirs, shout no when they shout yes, and so on. That too will quieten them down, no worries...
Keep flushing the toilet after 10pm and have a recording of their activities play back on full volume when they knock at your door to complain... Then pretend you are deaf and keep repeating "Eh what ? Come again?"
