It sounds like you live next to a Party house its a place locals use to entertain their friends and women. You may get somewhere with the resident if you tell him that if the noise continues you will call the police and tell them its a party house. Especially if you see alot of traffic going on, they are well known in the Gulf. My friend knew when a man was going to rent a villa near him what he planned on doing with it so she told him she would call the police all the time if it was a party house so he didn't rent it. She lucked out.
