Soundman2020 - Studio Design Forum

Hello, I have been away for some time and meanwhile the construction is almost finished, I was unable to change the original design due to the added costs (the budget was negotiated 3 years ago and now everything is much more expensive), but managed to fill the cavity with 5 kPa.s/m2 mineral wool, D...

Stuart,
thanks for the explanation, I was going to ask about the other benefits of an insulated cavity beside sound transmission

Also, does it impact the properties of the acoustic inside the room? (modes, resonances, decays)

Inner wall Surface Density(M) = 270 kg/m2 TL = 14.5 log (M * 0.205) + 23 dB = 14.5 log (270*0.205) + 23 dB = 14.5 log (55.35) + 23 dB = 14.5 x 1.743 + 23 dB = 48 dB Outer wall Surface Density(M) = 407 kg/m2 TL = 14.5 log (M * 0.205) + 23 dB = 14.5 log (407*0.205) + 23 dB = 14.5 log (83,435) + 23 dB ...

Concerning the airgap: I was going to compare the TL of the system with and without insulation, but in the following formula f0 = C [ (m1 + m2) / (m1 x m2 x d)]^0.5 the m1 & m2, mass of each leaf indicates kg/m^2. Isn't it a density unit instead of mass? I might have the rest of my post all wron...

Hi guys, thank you so much for your inputs, Glenn, such an amazing design, I hadn't thought of an airlock space for protecting the weaker isolation spot (the doors), and it's very elegant as well, I'm gonna present this new sketch to the project design and the construction company. A few clarificati...

Hi, I'm currently building a space for rehearsals with recording and mixing capabilities. My top priority is good isolation, neighbor's house is 3 meters away, and there's a gas station 10m further this is the plan I came up with: nu.jpg nu 3d.jpg the walls are hollow clay bricks, both sides covered...
