Soundproof bedroom

[ifsixwasnin9]

Want to soundproof bedroom in apartment to keep noise out and keep noise in. I thought 2lb MLV would work best but it's not recommended to attach to drywall. Drywall will not support weight of MLV. What can I do?

Not a lot, takes a lot to actually soundproof a room (like building a suspended room within the room). I just found long ago apartment living was just too rife with noise issues (both that I generated as well as the neighbors).

Just want to stop noise from one wall. And keep my Rock music from neighbors.
Wonder why drywall can't support MLV.
I see there's a paint with soundproof qualities on Amazon. Mixed reviews.

To do what you want requires a room within a room and an airlock. You are wasting your time and money approaching this like you are. You will have to turn it down, or buy a detached house with no shared walls.
Sound proof paint is just a laugh out loud hoax.

Maybe I can panel one wall with foam.

You will be surprised to find it will make little difference. Things like plumbing and electrical conduit and ventilation systems, will transmit a lot of sound, as well as through the building.

Sound proofing a wall is a entire science and it's about having like 2 walls separated from each other.

Sound is ransmitted in three ways- conduction (from physical connection), radiation (directly from the source) and modulation (conduction or radiation causes objects and materials to emit sound). You can treat one wall but the air and structure will still cause sound to exit the room. Treating one wall will affect the sound IN the room, it won't stop sound from exiting.

As others have posted, you can't 'soundproof' a room without creating a room wihtin a room.

Sandwich the MLV by putting a layer of 5/8" Type X drywall on top of it. The added mass helps reduce sound transmission. You won't stop noise transmission. Lowering it is the general idea.

MLV can also be hung over the stud bays and ceiling, so it can absorb energy from low frequencies by moving more easily. However and from experience, attaching it to ceiling framing is no picnic.

2lb MLV is extremely heavy, so you generally don’t hang it directly on drywall alone — it should be fastened into studs and ideally sandwiched behind another layer of drywall. In apartments, though, the biggest gains usually come from sealing air gaps, adding dense insulation, and using resilient channel/double drywall rather than relying on MLV by itself.

I've used Audimute absorption sheets and sound barrier sheets to lesson transmission from my studio and create "isolation" booths to prevent bleed from other instruments into microphones. These WILL NOT prevent sound from leaking into your neighbors apartment but MIGHT lesson it to some degree. https://www.audimute.com/acoustic-pro-sound-kit

Even rooms within rooms aren't 100% soundproof. I own one. Paint, foam, adding layers upon layers of drywall etc. have little to no effect. Also, I would not add hundreds of pounds to the apartment walls, you have no idea what they're made of and could cause severe damage or have a failure, collapsing the wall into your neighbor's apartment. Then, loud rock music will be the least of your worries.
