Soundproof wall
I've been checking into ways to bolster sound-proofing in an existing
wall, and it occurred to me that the recording gurus on r.a.p. may have experience doing this. Basically, it's one large, long wall that was built by artists in an NYC loft, so it's probably standard cheap sheetrock over studs. The current wall is acoustically transparent, even to mid and high frequencies. Is there any effective way to provide better soundproofing by installing a second layer of sheetrock with better sound blocking qualities? Any suggested materials or construction techniques would be much appreciated. |

Put up a second set of studs, not touching the ones already there. d --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

If you are really serious about this, get an expert to take a look at the situation - likely save you lotsa time and money on silly notions that will not work. ..... Phil |

The current wall is acoustically transparent, even to mid and high frequencies. If it's that transparent to audio frequencies, you may end up having to build a room within a room. There may then be problems with weight, depending on the construction. If it's the roof area of an old warehouse, they were built to keep the roof up, and not be used for storage. As has been said, you can get heavy duty sheetrock, but even using that, you will still get transmission through the floor structure. I've seen sheetrock laminated with a rubber based damping layer, which is even better, and putting rockwool between the old and new sheetrock layers helps, too. Is the floor concrete or wood? If the latter, you will have great difficulty stopping sound transmission. As Phil says, your best bet is to get a qualified person in who can also advise you on any structural problems there may be. -- Tciao for Now! John. |

Jack No, was done in the president's office where I worked, Staff meetings held, but everyone outside knew was being said. Installed lead, and you can scream your lungs out inside, but silence on the outside. |

Is there any effective way to provide better soundproofing by installing a second layer of sheetrock with better sound blocking qualities? Walls don't really block sounds, they just diffract them. Adding more and more mass by putting sheetrock on will reduce high frequencies by making the wall heavier and more rigid so that sound does not make it vibrate so much. However, this doesn't do much at low frequencies until you start getting into very very thick concrete. At low frequencies the solution is to float a room inside the room, which is expensive but remarkably effective. May I recommend the F. Alton Everest book on small studio acoustics? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I see the LS3-5As are like $700 used! Looks like you can purchase a copy of the box itself, maybe as a kit. Me, I had a pair of Radio Shack (Realistic) small speakers, acoustic suspension, but for their small size, they sounded pretty nice, just a single 4" decent speaker! Jack |

One idea to add weight and stiffness that should be easy for the OP to do himself is gluing ceramic tiles onto the offending wall. Often bargain priced wall and floor tiles available in limited quantities - the OP sounds like he needs a few hundred, 12 inch square tiles to cover his wall, plus a gallon or two of contact adhesive. ......

something to keep in mind re soundproofing https://en.wikipedia.org/wiki/The_St...nightclub_fire Indeed, and it should be pointed out that what was done there was not only unsafe but it really wasn't very effective either and only provided absorption at the highest frequencies. This isn't soundproofing at all, but the crudest possible acoustic treatment. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
