Solution against loud volume from the room?

My friend likes to stream on Twitch in the evenings. He plays with his buddies, laughs and just has fun. (Which I can't blame him)

Only on some days when he's off and I have to go to work do I try to fall asleep in the bedroom. But sometimes it's just too loud and I can't fall asleep, just like our children. (Screaming, with headphones… He just doesn't notice)

Is there a solution to cover his "GAMING ROOM" with some kind of foam (like in a music studio) so that even a Knossi can shout around in this room without being heard? We don't like to wear headphones while sleeping.

And we think the ABDECK variant is appropriate. Without there are other (better) solutions?

Talk to him and hope for understanding (probably not there)

How about if your husband would just be quieter and show consideration? Is actually normal when you live with several people in one house and not that women and children have to wear headphones or that rooms have to be insulated. Your husband should control himself when he screams so loud. It doesn't have to be at night. There are also neighbors who could be bothered by that.

Pull out the power plug. Or turn out the fuse.

Or pour a glass of water over his electronic devices

Perhaps one should teach the man that he is not alone in the apartment, that the woman has to be rested to finance his hobby and that he at least bears responsibility for the whole family… If my husband could not have separated from his PC to care for his child being there he could have played outside.

Foam doesn't help with volume… It is responsible for the acoustics itself. The only thing that really helps is a large cabin with thick OSB panels, possibly with insulating wool in between, or it is quieter, or you are looking for a house with thick walls
