John Sayers' Recording Studio Design Forum Archive

If one looks at my pics there doesn't seem to be a great deal of work been done, however, the outside frame of the studio has....
1 layer of building paper (blue)
1 layer of 19m/m yellow tongue
Another layer of Blue building paper then finally the weather boards will be fitted to blend in with existing house....!!!

Here are some recent pics
If anybody has any comments please feel free

Hey Mike.

Gotta work when the weather is good don't ya.
We are expecting rain tomorrow(Thursday) here and I just got rafters up today on a residential burn-out job.

About the time the rain goes away it will try to get cold again...and we still have to deck and weather proof the roof.

Keep on plugging away right?

Hi Guys,

I'm just about to install two double glazed doors into my control room.

The doors are pretty well contruction and have a 1" gap between each pane. The first door will run parallel along the studio wall and the second at 12 degrees.

From what I have read does this mean I am about to make a terrible 4 leaf mistake, in terms of using two double glazed doors between the control room and my tracking room?

Or could I use one of the doors, sell the other and get a single laminated door

Mike

PS these two doors cost me $1200.00 bucks ouch......!!!

you could install them, and if later you find its an actual issue replace it. but if they're good quality doors you should be OK. its not perfect or ideal but sometimes you need to make a trade off in terms of visibility versus some isolation loss. ideally if you could get single laminate doors you'd be better off but it depends on your budget and time to sell...

Hi Glen,
Thanks for replying.

I remember contacting you when I first bought these doors some months ago and yes we thought then, that there may be an isolation issue. My main concern is isolation and vibration.

However, the doors themselves are well constructed (better than others I've seen) and the fact that they are not running parallel but at 10 -12 degrees together is probably a good thing. I will fit them well and seal them as best I can.

all the best
Mike

Hi Everybody,
It's been a long time since my last visit and many bruises, aches and pains have long healed however, I'm sure there will be more too come.....hehehe Here's is some pics that are well overdue.....!!!
cheers
Mike

The next pic is where I had built the stud frame 70x35 on the floor then added the first layer of 16 m/m fire check plasterboard. Before the second sheet was added you can see a layer of acoustic caulk. In this case it is "Fullers" Acoustic caulk, which also has a four hour fire rating.

The whole assembly consisting of frame and 32m/m of "firecheck" plasterboard was then lifted up by four hefty Aussie musos and then rolled on 12m/m plastic pipe to move the assembly into position. Man it was very heavy work...!!! This process had to be repeated in sections and all moved precisely into position.

Note. That all the wall assemblies had a 20m/m x 70wide hard rubber foam called "Armaflex" glued to the underside of the bottom plates with contact adhesive. The "Armaflex" was much cheaper than "Neroprene" and did a great job in compressing the heavy frame to the slab, to help with isolation.

The Completed Assembly ready to be lifted into position on the back wall of the Drum Booth

In the next picture one can see the frame which separates the vocal and drum booth, there will be a window between the two, probably 10m/m and if I can find it 16m/m glass. You can see also that I have a ready put in the AC power which comes from the top of the frame, while the audio snake runs along the floor which will be between the outer and inner frames....!!!

In the next few pics one can see all the F17 hardwood inner joists. these have been designed by a structural engineer to hold up a weight of 25 kilo per sq metre. This weight will be the furring channel and 32m/m "fire check" plaster board.

Some more pics showing the F17 hardwood beams. You can also see at the top right hand corner a huge 240 h X 60 w m/m beam which runs the full length (11 metres) of the studio. This beam was suggested by John Sayers, for a number of reasons.

1. To add to the design in terms of carrying the load of the F17 and entire inner studio "fire check" plaster roof which sits inside between the Smart Joists of the main outer building frame. 2. To make provisions for the duct for the heating and cooling to go through the building to ensure isolation from the studios.

3. To alleviate and comb filtering and flutter and any other acoustic ceiling problems that may ensue. I'm not an expert, only just a beginner, however, I just hope after many many months of planning and some infrequent phone conversations with Mr Fix it (J.S) that the construction which is my responsibility will finally pay off....fingers crossed Mike

The next pic shows looking into the vocal booth.

Next pic showing the AC power and audio cable in the inner walls. Note the "Armaflex" under the frame, and the whole assemply being caulked so that all will be airtight...I hope
Well that's it for now, as i'm stuffed and ready for bed...cherrio god bless....

Mike

Thanks for sharing Mike - nice pics.

Thanks John,
I've had the flu for the past week and am just about to put some more pics up. Having said that, I have had the aircon guy in this week and he asked me me to ask you, if I should use acoustic duct? as he is worried that sound from the vocal and drum booths might bleed sound through the ducts into each studio while tracking.

Is this possible and what is the is the best way to combat this? He suggests acoustic duct, the stuff with the holes on the inside or should I make some of those bafel boxes up and put one say between the vocal booth and drum room and drum room and large tracking and finally one from tracking just before going into control?

In the meantime on with the pics....

"Rondo 581" acoustic furring channel, I discovered through my next door neighbour and so I decided to get some of this wonderful but prohibitively exspensive product @ $22.00 AUD per 3.6 metres. The engineering specs are amazing for a product which has only has one leg....!!!

But I figured if ya stand one leg and think in terms of isolation it makes bloody good sense doesn't it....!!! Suffice to say the design will hold up 25Kg per sq metre which as you can see by the following is very good.

Note the Furrinf chanel is screwed into the F17 hardwood using 25m/m "S" plaster screws as recommended, by Rondo.

Rondo advise not to use nails as the weight 25kg won't hold and one may in deep trouble...!!! As a chippy myself I am always aware of safety as at the end of the day the people we serve are more important than the studio itself...!!!
