Generally at least once a year if not a couple few times a year I will host a party at my house. These parties can last into the early hours of the morning. The longer they continue generally the louder the music the louder my guests become.
I have sliding glass doors and French doors throughout the back of my house which basically open up the whole back to my patio area and pool area and outdoor kitchen this gives the flow from the inside the house to the outside of the house so guests can come and go wherever they want.
My system can reach well into the low 100+ dB's without a problem. And with the whole back of the house open I'm sure half my neighbors in my neighborhood can hear the system and my guests. Now generally most of the time my neighbors are invited to my party so they know about it in advance but on the few occasions they weren't invited my thoughts are oh well. I don't do it all the time and I don't expect my balls busted when I do. Just like when my neighbors like to blow off fireworks on New Year's Eve, Fourth of July whatever other occasion they feel like doing it I have to deal with it.
I guess basically what I'm saying this as long as you're not doing it all the time then it's okay and if you do have that one sour neighbor that just likes the Biatch. Just do what I would do tell them to go Fuckk themselves
