Shipping container studio (gulp)

Hello

Please can you advise me on my situation. . . .

I have recently moved my studio to a shipping container right on the river Thames here in London.

Don't laugh.

It has been double lined with plaster board and filled with some form of builders caulk between the layers. So there is an amount of protection from the raw metal resonance of the container.
The dimensions are 6m x 2.14m x 2.2m high.
It sounds HORRIBLE.

Here are my starting points for treatment.

The console will stretch about 120cm from the rear 2.14m wall.

I will put 180cm long x 60 cm high perforated hardboard panels lined with 100kg/m3 mineral fibre 10cm deep along the side walls overlapping the operating level of the console and then 3 successive 1m wide x 60cm high panels of fabric faced, 10cm deep mineral fibre (same density) above the pegboard, evenly spaced from behind the console to about 4m along the room.

On the 2.14m wide wall behind the console there is a circular window (nice). Either side of that window I will put 120cm high x 60cm wide plain hardboard faced panels filled with the same 10cm thick mineral fibre for lowend absorption. They will almost hit the corners.

On the ceiling I will put the following,
2 x 80cm x 60cm x 10cm boxes over the console with a perforated hardboard face and filled with 10cm thick 100kg/m3 mineral fibre.
Behind these I will lower the depth and have a further 2 layers (meaning 4 boxes) of 5cm thick mineral fibre. I was also going to scatter the facing material from perforated to plain hardboard.

So thats a starting point. i realise the best way to do this is to hack stuff up there and then have a listen but has anyone got any recommendations/advice/warnings ?

many thanks

That is an astounding problem.

Ethan?

I'm pretty sure John L Sayers successfully designed a studio in a shipping container.

Yep, here it is: http://www.johnlsayers.com/Studio/Mainpage/MP-Mark.htm

I don't know what that means, but the speakers should fire the longer way down the "room."

Reflection points need 100 percent absorption, so you don't want any sort of hard board there, perforated or not.

Any chance you can post a photo?

Glen - Thanks for that link to Jon Sayers' site.
That looks like the best way to line the container !

It gets me to thinking that maybe I should "Stud" wall the whole thing and line it with mineral fibre then face it rather than just putting panels up. I'm quite keen to keep some "air" in the room acoustically but I want to try and gets as uniform a response as possible.

Ethan,

Do you suggest I just line the mineral fibre with acoustically transparent fabric ? Will I not abosorb everything then ?

Are you sure you want a photo ?
It is a rectangular container - just like the one on Sayers' site, lined with plasterboard and with a glass entry door. I would be happy to oblige with a photo if its informative though !!!

thanks for any help

regards

Dilip
