Thanks for reply! The goal is to record their noises and play them back with speakers. Maybe that will make them think...
* They are over 60, they drink, they speak some dumb things at night loudly and their voices are some of the ugliest in the world. And when this bitch shouts at night I wake up and have some stress.. They are driving me nuts! That's the last thing I am doing before contacting the police with my problem.
