I've just started renting a condo and I'm in a corner unit with my neighbor's door right next to mine.  They have a mentally challenged daughter who vocalizes a lot.  I'm a software developer and I work from home, so someone yelling and screaming from time to time can be pretty distracting.

I've added weather stripping around the door so it's air tight, and that's helped the sound a bit, but not enough for my needs.

I've looked at some options, but reviews are all mixed.  Some of the things I've looked at are mass loaded vinyl, acoustic foam panels, and fiberglass foam panels.

Obviously it would have to be non-invasive (renting), I'd need to be able to make a hole to see through the peep hole, and any solutions would need to go on the inside of the door.

Any advice/suggestions are greatly appreciated!

Other Soundproofing Questions / Re: Sistering joists--any point in putting green glue in between?

just use construction adhesive and sister correctly, stiffening the subfloor will be better for noise anyway.
Your clips are the decoupler from the structure.

Other Soundproofing Questions / Sistering joists--any point in putting green glue in between?
« Last post by shayyadin on April 28, 2019, 02:44:29 PM »
I am in the middle of soundproofing my basement ceiling. Overall project is to fill bays with roxul, attach noise isolation clips to bottoms of joists, furring channels to clips, and quiet rock to furring channels.

After taking down the old ceiling, I noticed that some of the joists had been notched improperly and were showing some cracks. Structural engineer said not a problem yet but recommends sistering the joists to prevent issues down the road. Sistering involves putting construction adhesive between the old joist and the new, then bolting them together. Obviously, the bolt represents a direct coupling.

Any point in using green glue instead of construction adhesive? I'm sure it doesn't do any harm, but it's a waste of money if it's not getting me anything.

Soundproofing your Condo, Townhouse or Bed & Breakfast / Re: Cement ceiling impact noise

just make sure your new frame does not touch walls and ceiling.
make sure the frame can hold 10-20 lbs sqft depending on how much reduction you want.

Best rooms can come in at 25lbs sqft.

your room value will be dictated by the weak spots like doors.

NO SUCH THING AS 100% SOUNDPROOF!
there is always a sound wave low enough to go through these walls...at some value.

room within a room (rwar) is always the best if you have the space for it .
depending on span you would lose 12" to 14" of ceiling height

That's fine as my ceiling is 2.85 m high.

What about each side of the room? How much space would I lose in case I want to make the most soundproof room possible?

Also, what kind of Decibel reduction should I be expecting? Will the noise disappear completely?

Thanks!

Wouldn't building a room within my room be a better option as I also play loud music and drums?

Hi, I just got contacted by your employee saying that you don't have that material anymore, is there anything I can do for this problem? Thank you.

make the wall as heavy as possible and insulate the cavity.
seal the wall like a fish tank, air tight / water tight.

if you can use products like mass loaded vinyl this will increase the STC rating of the wall.

Also, what ever weight you make the wall (lbs per sqft) make the door match.

I'm not sure if double frame construction or single frame, but I assume only single frame given how cheap the build of this unit is overall.

Bedroom 1 would still be an issue with my proposal, but i've pretty much abandoned this as just a storage room now. My only goal is to make a much quieter living room and Bedroom 2.

I'm actually in Australia, so calling you would be difficult.

Would you be able to give any general advice on this forum about sound proofing materials for inside wall or anything I should keep in mind when attaching wall to existing floor/ceiling etc? maybe some extra sound dampening matterial for the joins etc ?

Thanks for your time.
