Q(estion) for J(ohn) 'bout B(affles)

[sjoko2]

Yo! Bretheren!
Like your thoughts on this one:

I originally build one large baffle for the main tracking room, dimensions:
4'2" high - 6'2" long - 8" deep frame, to accept a 6' x 4' core.

The current core is a high density pressed panel, and the intention was to line this with diffusion material on both sides.

Now this creates 2 problems:
1. The core makes the whole friggin thing as heavy as a tank and hard to move.
2. I don't need a core with a high STC rating.
3. I mainly need absorbsion - accross a wide frequency range.

The baffle is the largest one in the tracking room. Altough its use will be multi purpose, its key function / position will be in front of a drum booth (*note). Its closest adversaries will therefore be kicks and toms.

*note:
- The drum booth is a 10' x 10' x 9' straw lined enclosure, with a "poored-in-place" rubber floor and an open front (into the main tracking room).
- The booth has a hinged 4'4" x 8'4" roof section, which can be raised or lowered in order to vary the acoustics.
- It has been designed to allow for effective close-milking of drums and percussion with minimum interference for each microphone.
- The open front leading into the high volume tracking room allows for the capture of ambiance.
- Adjustment of the hinged roof varies the ambiance from moderate to huge sounding.

The baffle's key function is to further reduce sound transmission from the booth to the tracking room.
I therefore thought a kind of slot construction might be best? Perhaps with variances in the slot spaces to allow for effectiveness accross a wide range (lower ranges are BY FAR the most important here!!).

If you think - really this should be kind off a 'carry about' trap

Suggestions very welcome, as my brains are fried from building anything, designing anything - ever again. I'm cured - positive, really, I mean it. I'll do it different next time. Next time? WHAT next time? I'll still do it different next time.

ehhhhhhhh remember that conversation we had Mr. Sayers? When I had just started? Me explaining I just really wanted to do it all myself? I'M A NUT!!!!
This does not mean nobody should build their own studio, absolutely not!! I have saved myself a very large 6 figure sum and got it exactly the way I want it (I think). And it sounds sooooooooo good.

PS Uru is getting loads of Cali radio play
another PS In January I will startg to make drum sound samples, to set some template sounds for the room, with Aynsley Dunbar and DW drums - I promise I'll post some stuff

Hi Mate - check this out - it's a PDF acrobat reader file as it's the easiest way to exchange drawings.

Glad to hear that you are better and that Uru is getting her just rewards

Although it has been a hard road building it yourself I'm sure the gratification of having acheived it is unmeasurable

Cheers
John

Wow John!! Thanks a million for that! The broadband low-mid was exactly what I was after. There is already a lot of low end trapping in this room (in the roof)

I can remove the core entirely without a problem, as the frame has 8 steel corner reinforcements.
I think I will vary the plank and slot widths.
One thing I'd like to try. I have some nice 1/4" birch finishing ply, so what I could do is instead of having 2 peaces of ply running at angles, I could have a continuing arch. Might be interesting to see what that would do, as one side would have a lot of debt in the center - the other side debt at both ends.

Thanks again
