Hi there,

This is my first post in the forum. Thanks for reading. My wife and I recently moved into a duplex with a detached garage. I hired a contractor to build a soundproof room within that space. He used H-Bar clips, double 5/8" drywall with green glue, etc. He has now finished the job and there is excellent soundproofing, but there is no ventilation to the room. I would like to add a vent system and am wondering the best way to go about it.

The room before soundproofing was 10'x20'. The soundproofed space is about 9' x 13' now and the remainder is part of a storage space (approx 6'). I think I would like to vent to the storage space. I was reading an article on soundproofingcompany.com and found this image.

https://www.soundproofingcompany.com/soundproofing_101/how-can-i-ventilate-a-sealed-soundproof-room

It's the second image down the page.

My question is, do you think that creating 2 holes in the wall (intake and exhaust) with dead vent mufflers is the way to go? It seems like it would be connecting my soundproofed walls to the storage space, and maybe a bit counter-productive?

I'm open to any thoughts and suggestions.

Kindly,

Jamie

if your doing this for room absorption and reflection it will work.
BUT, if your doing this to reduce impact / footfall noise it will do very little if anything.
You would need to decouple using clip and channel or double joist system.

I'm having problem with noises from neighbors upstairs. Getting a proper room in room solution is kinda expensive (quoted upward $20k for ceiling and walls, without noise clips). So I'm thinking to DIY hanging rockwool panel or sticking them to the ceiling somehow. Does anyone have experience with this kind of DIY? What kind of reduction is possible? I'm thinking to start with a layer of 2 inches and adding another layer if that is not enough.
Thanks.

Hi All,

Wondering if I can get some input on reducing sound transmission. I live in an area where single family homes are connected. We don't technically share walls with adjacent neighbors, but the houses are basically touching if that makes sense. We're renovating at the moment and I'd like to limit as much noise transfer as I can from my neighbors in our open living room/dining room/kitchen area (on the second floor with garage directly underneath). We don't have the budget to treat every surface throughout the house (ceilings and floors).

This is what I'm working with:

I'm planning on treating the walls marked in red with rsic clips, hat channels, rockwool safe & sound, double dry wall and green glue. 
-Is it worth going the extra mile with the rsic-clips knowing that there'll be flanking noise through the untreated ceiling and floor?
-I've read that rockwool safe & sound is not measurably better than standard fiberglass insulation. Should I not bother with this either?

Thanks in advance for the input.

thanks. seems i will make more accurate measurements and post in "Soundproofing Windows and Doors".

Adding a soundproof curtain might get you a couple db change at best.. Adding the second window with the greatest air gap between the two will get you far more reduction.
At 2-3" gap you could see 10+ db reduction.

recently moved into high-rise luxury building in heavy traffic center. my current bedroom facing street, floor to ceiling sound-proof window. With window open, around 90 db. With window closed, reduced to 70 db.
We would like to further reduce bedroom sound to 60 db or 50 db if possible. should we buy sound proof curtain or add another sound proof window?
thanks for the help!

Thats great your taking up the trumpet, here are the answers to your questions.
I would still advise you on giving me a call direct for some build variables.

1.  If that amount of dampened mass is acceptable for the amount of reduction needed then ok but if you are trying to get more reduction in the lower frequency range then it is not enough especially without a decoupler in the design.
2. just replace the door with a solid core door. you really do need a heavy solid door with airtight seals.
3. free stand the desk.
4. lets review that last, due to the absorption needed in the room those might not have enough effect.

Call me when you have some time to discuss.

I have a question posted in  “other  soundproofing questions” that has very few views and remains unanswered.
Do I have to move it here to have it answered?

Thanks,
