All understood, thank you. I'd have never thought of that for the reason for green glue requiring at least one porous exit, but it makes total sense right enough. If I can get away with the existing 12.5mm plasterboard and 6mm of cement board it'll be happy days for sure, as it brings the short fron...

Thank you Stuart, you are totally correct about my motivations, and please feel free to rant away to your heart's content! 1392 OK, a few more twists that you could take into account as you work through the process of coming up with the perfect room design: If you need more mass in a thinner package...

The more I read about the Genie clips and furring channel you recommended for the left wall in room 1 Stuart, the more I like it. Having studied IR761 they seem to confer many of the benefits of staggered or even double stud walls, and are certainly easier to retrofit. IR761 cites resilient channel,...

Cheers Stuart, very useful information indeed thank you. I'll be able to do something similar with the bass traps at the rear of the room.

1382 I think grilles are fitted to plenums, not to the duct, and a plenum usually looks like a box with an inlet for the duct and it holds the grille for the outlet. As the plenum is bigger than the duct, maybe the slowing down of the air speed in the plenum keeps the air noise quieter than my meth...

Starlight, I'm no expert, but I think part of the purpose of diffusers is to guide airflow in certain directions. You can get ones that direct it down, or to the left or right, swirl it about or what have you. There are ones that make use of the "Coanada Effect" which causes the air flow t...

Finding the good stuff has been something of an adventure, especially as I have no prior experience of this sort of thing. My plan is to do my best, but also design the system such that the grilles can be replaced relatively easily if they are too noisy or what have you. In our favour at least is th...

1374 That is amazing information, thank you. :thu: 10dB improvement in isolation will totally do the job, I should clarify: 10 dB is probably towards the limit, and would need "all of the above". ie, take off existing drywall, beef up framing for heavy door, seal wall interior well, add c...

That is amazing information, thank you. 10dB improvement in isolation will totally do the job, allowing me to crank the monitors to check the kick and bass, and record amplified guitars with substantial low end without these being heard in room 5. So a couple of extra layers of drywall and green glu...

New build small size high isolation project

Impressive! The door frame you have laid out on the sheet of OSB looks super sturdy, I'm wondering what thickness of wood you used for it? Also, having never seen or used the stuff myself, I'm intrigued by the shiny white covering on top of the duct liner in the silencers. I'd always imagined the fl...

Room 1 is where I mix and record most things, including drums. Room 2 is used less frequently and usually only for quieter instruments, so reducing sound transmission from there is not as big a priority as room 1. We've established that transmission loss from Room 1 to the landing is poor and has si...

Cheers Stuart. I recorded a six piece rock band here last week, all playing live at once; Drums in room 1, with keys (DI) and bass player. Bass amp in room 4. Percussion and electric guitar in room 2 with a wall of gobos between them. Singer doing guide vocals on landing. The difference from before ...

Amp Riser Effectiveness

Here are the test results for non impact sound transmission from room 1 to room 2 (adjacent via the landing) with an REW sweep with the amp on and of the riser. Same test setup as previous post; top view.png Sound transmission to Room 2 - on and off riser.png My untrained interpretation is "no ...

Amp Riser Effectiveness

Thanks Stuart. Indeed, such a relief that it works so well after all that work and additional expense over building it as one. I can't remember if I've mentioned this before but the design is very similar to one in Rod Gervais' book that he mentions using to cover an entire floor. The benefits are c...
