Starting from scratch with 3 bare Squash courts as follows:
* Plans are drawn facing North.
* 3 squash courts - Double brick with cavity and 2 inch concrete. Each court is isolated from the other and do not share any floor joists.
* Dimensions: Squash courts approx. 9.7m (L) x 6.4m (W) x 5.5 - 6.0m (H)
* Floor: 19 mm floor boards on floor joists. Floor (joists) raised on stumps.
* Do I soffit mount my main UREI 813a monitors - I have read on Lansing forums it makes a huge positive difference soffit mounting these speakers.
* my main concerns are :
* Line of Sight
* Machine/ Computere Room ( do i need one ?) * I'm trying to squeeze the tape machine on the right behind a sliding door?
Studio furniture and location of Racks ( whether they are behind the engineer, on each side like wings - or sofit mounted into wall ? )
* Future 'surround' implementation - positioning of monitors ??
im thinkin of the office combined with tech room at front - up stairs and where it says tech room - have recriational there ie: table-tennis etc ..
( above anneneties) ... and also kitchen for clients.
the room next to terrace can be lounge TV- internet-playstation etc ...
The air lock below office ( 1st tracking room ) can be used to quickly seat unexpected clients while im in the middle of it - and also a place for them to unload before moving.
What do you guys think about NATURAL LIGHT ?? - I can bring it in as a sky-Light from above ... it can come in from the sides of the false ceilings - so that it is soft and doesn't burn through.
Natural Light = Sound Transmission = money.
* Note - funny shapes not necessary in control room - just an idea
Any comments appreciated.

just as answered in studiotips - Urei's can be mounted in baffles. i'd drop the air lock on the back of the CR and just block off the whole section to separate reception from the rest of the hall.

Yeah - I was thinkin 'bout droppin the airlock behind the CR too - I'm sure I can work something else out there and utilize the space more efficiently. Thanks ;)just as answered in studiotips - Urei's can be mounted in baffles. i'd drop the air lock on the back of the CR and just block off the whole section to separate reception from the rest of the hall. http://img142.imageshack.us/img142/3167/tonymitev2pw2.th.jpg http://img241.imageshack.us/img241/9414/tonymitev2frameeb2.th.jpg
please comment on latest revision and check out upstairs post-production room and ISO booth - does it make sense ?
i think you need air locks on the live rooms more than the control room since noise coming into a live room while recording is likely worse than in the CR... maybe there's a way to segment the hall behind the CR and main room so you have a pair of air locks... and potentially useful for amp booths etc...
i had plans of those segments in the hallway also - just didn't add them in the drawing - I don't know whether I'd be using them as ISO booths for amps ( maybe if i were desperate and run out of options . That side of the building ( the hallway) is a double brick cavity wall - but my neighbours are living over on that side and I would have to soundproof the hell out of it - Can always be done in the future I guess. thanks for your feedback - greatly appreciated !i think you need air locks on the live rooms more than the control room since noise coming into a live room while recording is likely worse than in the CR... maybe there's a way to segment the hall behind the CR and main room so you have a pair of air locks... and potentially useful for amp booths etc...
here we have added segments in hallway and wings to console.
ALSO - is there a rule on how far my soffit mounted UREI 813 monitors should be from the outer wall? - ie: can I push the room back further? I have approx 1100 mm between the central front position ( where you'd place your centre monitor /plasma ) and the outer shell. ( see in red ).
Any +/- 've comments to any of these?
Can I push my room back further?
This will allow me some room to angle the tape machine around so that I can view the VU meters alot easier.
Is there a REASON to leave that much room behind the soffit mounted UREI main monitors?
the bass trapping... needs space... maybe a meter bridge for the tape units? but if the monitors need to move back, then move them... you have enough space overhead for good trapping so the floor plan can be more flexible.
thank gullfo - your expertese is greatly appreciated.

I'm still umming and arrring about soffit mounting - as far as I'm aware, the only 'true ' way to soffit mount speakers is to put them in a concrete pilar - otherwise it defeats the purpouse.
What's to stop say 100 Hz moving back behind the speaker in soffit mount?
Also, with soffir mounting, I'm limited when it comes to tuning the room - as I can not move the speakers all that much and come time when I want to upgrade, I'll have to tear the wall down and re-build.
Correct me if I'm wrong.
in a proper baffle construct, you'll have things pretty well sealed and the baffles extended to accommodate the monitor size. behind the baffle will be lots of space and you'll use that to building bass trapping which will deal with anything making its way "back"...
I've been searching the forum for baffle how to's and what not's and diagrams etc.. Is there a baffle 101 site anywhere ? I know there are 101 ways to f*#k it up.in a proper baffle construct, you'll have things pretty well sealed and the baffles extended to accommodate the monitor size. behind the baffle will be lots of space and you'll use that to building bass trapping which will deal with anything making its way "back"...
given the monitors, tape unit cabinets, etc. you're not likely to find a "here's how you professional mount a huge pair of monitors and build a pair of machine closets which preserve the bass response, RFZ, and the acoustic neutrality so highly sought in very expensive studios" 101 type reference...
that said, check out John's designs - including Meow Mix which may have some clues on the right approach.
Can anyone comment on whether they think there'l be major differences in the way I line my ceilings.
The cheaper and easier option is to line the existing rafters with particle board then dense plaster board ( after filling with dense ridgid insulation).
Then I could suspend a 'false' ceiling beneath - I'm not sure whether to make that false ceiling out of an insulation filled frame with fabric stretched across ( like a broad band absorber ) - or - have it made of a more ridgid material like plaster board ( maybe 2 layers so it doesn't rattle ).
Any coments appreciated.
Comments on ceiling.
What room is this for? Still the control room?
How much absorption is needed in the room for the design RT60?
Where are planning to put have the rest of the absorption?
This question I thought applied to all rooms - even though they may have different answers. I still plan on treating the rooms with: COrner bass traps ( superchunk type ) broad band absorbers ( walls & ceilings) Diffusers ( walls & ceilings ) etc ..Comments on ceiling.

I'm looking at raising the bearers sitting beneath the floor joists onto industrial rubber ( escalator hand rail ) to de-couple the floor from the brick piers which are attatched to the brick wall.
I'll probably put the same rubber beneath the plate ( beneath each stud ) for the inner walls.
Is there anything else I'd have to consider doing this?
Yes; why? You wrote in your first post that the rooms do not having joining joists. Have you read this? Random constructing of floating flors wiil either do nothing, or probably make the acoustics worse.

The 3 rooms are independant of EACH OTHER - BUT - the floor is still sitting on Floor Joists, which are sitting on bearers, sitting on piers connected to the wall. The floor boards at the moment are still touching the wall at the perimiter. So first, I'll have to cut around the perimiter so the vibrations off the floor do not transmit to the wall - Hence the rubber isolation of bearers from the piers. This is the only option I have other than pulling out a perfectly good floor and pouring an expensive concrete slab. I hope I'm making sense - am I missing something ??Yes; why?

Fro your last post I am assuming that the bearers are continuous. How are they going through the brick walls? If they are, then there will be flanking through the: brick wall bearer brick wall path. This would mean no significant improvement in LF isolation no matter what you do to the floors, joists, and bearers. Andre* 3 squash courts - Double brick with cavity and 2 inch concrete. Each court is isolated from the other and do not share any floor joists.
Each court ( of which there are 3 - see drawings ) is built within a solid brick shell. ie: each court has a double ( cavity ) brick wall surrounding its perimiter. As the centre court shares walls with the 2 outer courts, it also means that that wall on either side is considered " double brick " from either side ie: there are 2 rows of bricks with an inch cavity dividing each court. These brick walls go ALL the way to the ground ( except for a small opening that was intended for ventelation breeze to go straight through to avoid moisture build up - kind of like a man hole. I will address this by filling it with layered insulation ( Super-Chunk style ) stuffed in a plastic bag. Just to conclude - the full black thick lines on the drawings = double brick cavity wall. This means that these walls have brick piers on the insides where the bearers lie upon which the floor joists lie, upon which the floor boards are fixed.I'm getting confused.

By isolating the floor from the walls - I am trying to stop vibrations from the floor transmitiing through to the the wall - especially the outer brick wall.

Do the bearers run between the double walls separating the rooms?This means that these walls have brick piers on the insides where the bearers lie upon which the floor joists lie, upon which the floor boards are fixed.
If the answer to my question above is "no" then you do not have to worry about vibrations getting through, because the are not attached to the other wall. AndreBy isolating the floor from the walls - I am trying to stop vibrations from the floor transmitiing through to the the wall - especially the outer brick wall.
To help clarify, the attached what I understand it to be. The left wall being the outside.
