Hey Jo,

It's an AEROVAL - CLIMAVITAL reversible monobloc system based on a 5kW Toshiba pump, built by a company in southern France. I use that system most of the time because it has a very small footprint, is easy to install (no pressurized copper tubes, i.e monobloc), and it is dead quiet for a 5kW system. The noise level is so low on the studio side of the ducts, that often we cannot even measure it. The machine itself produces under 50dB R(w) at full power - so it doesn't require a too heavily treated or distant central airco room. It is slightly modified to meet our strict noise level requirements.

In multirooms facilites, it's a good system too since you can basically have one per room and save quite a bit on the electric bill by being able to turn on the Airco only where it is needed. So in short, it makes things easier.

There is no progress this week as the ceiling hangers haven't arrived. Should come in on Friday or Monday, after which work can recommence.

what about balanced power?

Hi Darius,

Are you going to add a cabinet for balanced power? Or maybe two (one for the analog gear and one for the digital gear?).
something like this: Wall Cabiniet Balanced Power Systems

Hi Sander,

There's a big expensive electrical something being installed, but i don't know the details!

Hi Darius,
Don't save on electrical cables (i am sure you already have something cool in mind), even if it sounds esoteric, I find it makes a huge difference.

Hi Guy,

I have to admit, my knowledge about electrics is very limited, so i've left the decisions about specifications and materials to the studio designer and a professional electrician!

The last materials arrived on tuesday and work started again yesterday.

I'll get over there on saturday to take some new pictures.

Hey Darius, ziet er nu al veelbelovend uit! Mooi room design ook! Veel succes met de verder opbouw en installatie. Als ik ooit weer een mix/opname project doe in nederland probeer ik eens langs te komen. Even koekeloeren

Succes!

Wow, I didn't expect the difusors would be hanging at the ceiling. It sure looks great!

I'm still very interested what you guys are using for getting balanced power. Are you using 2kW trafo's and who is making them?

Thank you!

Only 4 of them are - and you will see in the next week that another structure comes around them... The other 8 are in the back wall in front of the bass trap systems.

We are using a professional electrician and common sense...

Are the diffusors on the ceiling on the first reflection points?

Yes and... no. First reflections are only a part of the equation but it's not only that. It's also about optimizing the diffused field over the sweet spot, so their placement is such that the engineer (Darius) will hear even less the specific speaker location - the ceiling virtually disappears.

This is estimated by using probabilities / models of the distributed diffusion. From that and E.R. we extract what their best placement is, what is the optimum amount of diffusion needed and the theoritical bandwidth needed. We then adapt the size and depth (sometimes the pattern too) of the standard diffusor design to fit these requirements. Darius's diffusor gained a few centimeters in all directions compared to the original design we use as a basis.

Hi there...

looking great, but these are not acoustic hangers right? We have exactly the same here in our country and they are not acoustic.

Cheers.

Well, actually, they are.

If you look closer, you will see that black polymer stripe in between the two plates, which is used as a decoupling material, interfacing between the hanger itself and the rail clip system. See the red arrow.

The hanger goes through the top metal plate (without touching it) to the bottom metal plate (pointed by green arrow) to which it is fixed. It is facing downwards. The top metal plate (blue arrow) clips into the rail system from over the bottom one. Therefore, this way the load of the ceiling is indeed put on the polymer which rests on the bottom plate (green arrow): it's decoupling.

BUT those are not as efficient as Sylomer or spring based systems. And for a good reason: because it is simply not needed. Darius's studio is a bunker design (self-standing massive box in a box design), whose only surface which is in contact with the rest of the building is the bottom of the 30cm thick concrete sub-structure (see first pages).

This concrete sub-structure is interfaced / separated from the building's original concrete slab by a decoupling polymer, calculated to provide an effective decoupling frequency of just under... 10Hz. The ceiling is hanged from the outer shell which rests solely on this decoupled sub-structure.

Which means that the whole studio cannot be subject to external parasite vibrations - including the ceiling. So, no theoritical need for particular 'acoustic' ceiling hangers, but to be thourough, we still put those - which are already providing way more than we actually need.



EDIT: actually the model used is the version interfacing between upper rail and lower rail network. So, same as if with only a single rail network - but they are not interfacing with the hangers themselves but with the first rail network (top one, same-same though, see second picture).
