"Sound Reducing" a Bedroom Studio in 1st Floor Apartment
« on: March 26, 2017, 10:25:14 PM »
Hi all,

I recently leased a finished first floor apartment in a duplex, and will be using studio monitors for audio production in my 11'X11' bedroom.

I want to help reduce noise/especially low end frequencies that could leave my bedroom and escape to the floor above.

I've read countless articles and watched tons of videos that seem to boil down to redoing the drywall ceiling with products such as green glue, mass loaded vinyl or peacemaker, which is not gona be possible in this space I'm renting.

*I have yet to test this as I don't move in for a few weeks, but I'd appreciate some advice on this before I spend about $400 on the project

MY IDEA:

I'd start with some rubber isolation panels under my speakers to decouple them from my desk a bit and remove low end from spreading to the bottom

https://acousticalsolutions.com/product/vibration-isolation-pad/

I was wondering if make EIGHT 3.5 x 3.5 (≈12 sq ft) sound absorption panels to be hung about 1 inch from my ceiling with about a 6 in. gap between each, if this would help absorb low frequencies/general noise or do absolutely nothing.

I've attached my "rendition" of what the panels would look like on the ceiling.

Here's what they would be made of:

- Fabric
- 4 Pieces of White pine 1"x6"x3.5' wood for a square frame (http://www.homedepot.com/p/1-in-x-6-in-x-8-ft-S1S2E-Standard-Band-Sawn-Eastern-White-Pine-Board-235729/206920627)
- A 2 cardboard squares sandwiched together with Green Glue Compound (http://www.acoustimac.com/soundproofing-green-glue-single?gclid=CMfmqIWZ9dICFdCCswodf8QGcg)
- One layer of 3" of ROXUL - SAFE N' SOUND Insulation (https://www.lowes.com/pd/Roxul-59-7-sq-ft-Unfaced-Rock-Wool-Batt-Insulation-with-Sound-Barrier-15-25-in-W-x-47-in-L/3394032)
- 2 small 1"x36" strips of balsa wood to create a 1" air gap between the next layer of insulation (If it will fit) (http://www.homedepot.com/p/Waddell-36-in-x-1-in-Hardwood-Square-Dowel-8316U/100572443)
- A Second layer of 3" ROXUL - SAFE N' SOUND
- Another 2 cardboard squares sandwiched together with Green Glue Compound (If it will fit)
- Fabric

Each panel would be roughly about 16 lbs if my math is right so 2 hooks rated at 10/15lbs each should be good to hold each panel up about 1 inch from the ceiling. I've included some pictures of the panel cut sideways and longways to show my thinking.

Bottom line is, would this do a lot to reduce sound from traveling to the room above me? It may be better insulated already we haven't tested it yet, and luckily there's no central air or ducts in this home as it was recently renovated (we're the first to live in it) plus all the double paned windows are brand new.

I'd love any advice on other options as well or if my approach seems overkill or not even close to what's required to lessen the sound passing to my 2nd floor neighbors.

Thank you all so much!

Also would adding Peacemaker insulation also help? or is it overkill at that point? Thanks! http://www.audimutesoundproofing.com/sound-barrier-soundproofing-a-room-how-to-soundproof-a-floor.aspx

This will acoustically condition the room but will not reduce the low frequency that will pass through ceiling and walls.
The only way you are going to get good low frequency reduction is by floating the drywall on isolation clips and channel.

You could see a couple points of reduction but this will not do 50% reductions...

Remember that the walls will still transmit low frequency to the upper floor going around the ceiling.

Thank you Randy!

I think I'll opt to just add a little more rubber underneath the speakers, and then invest in a good pair of headphones for the rest of the day...

Thank you!
