How can I DIY soundproofing for my bedroom so that no one can hear me from outside of it.
So I'll summarize why I need this. I can't afford to move out of my parents house and I need to hide my interests from them. My controlling dad would freak out if he knew some of the things I (an adult) was doing or listening to. I get paranoid that my family can hear me, so I have my speaker on a quieter volume than I'd like, and whenever I'm doing a ritual I talk at a voice level somewhere in between a whisper and a normal inside voice level. I want to feel so sure that my parents can't hear me.
The specific sounds I need to block out are:
• Talking at a normal inside voice level
• Ringing my little high pitched singing bowl
• Playing my hand drums
• Listening to music through my speaker
• watching TV
My parents en suite bathroom shares a wall with my bedroom. That wall is a chalkboard wall, so I want most of that usable as a chalkboard. I don't mind framing a big rectangle of it with some sort of soundproofing. The rest of my walls are mostly covered with posters, pictures, art, etc that I've added over the years. I am thinking about removing some things that I don't care about anymore and moving some of the other stuff around to create big blank spaces on my walls where I can sound proof. My door has a gap at the bottom, so I put a door draft stopper to block the gap. I'm thinking of moving some things from my door to make a blank space on it for soundproofing.
So how can I DIY some sound proofing for my room?
