John's Drum Booth layout previously posted by Kendale

Last year Kendale posted a jpg of a layout of John's for a 1.995M x 2.850M x 2.550M drum booth in response to someone's query. I am just wondering if you could elaborate on the internal treatments for each wall (ie: the brown coloured wall = is this a slot resonator wall? and are the grey walls simply absorbtively treated) I assume the panes facing the front of the drumkit are sliding glass doors? Any other details to help get this design built would be much appreciated including ceiling treatments etc. By the way: what alterations to dimensions / treatments if any would be indicated (modally speaking) if I can afford an internal ceiling height of 9 or 10 feet or even higher? I tried to upload a copy of the jpg but the pixel ratio of the original would not be accepted. Kendale's original posting was on the following thread: viewtopic.php?t=9558&highlight= Many thanks, Wayne P.

Aloha Wayne,

the brown coloured wall = is this a slot resonator wall?

Yes, however, depending on how "live" you need/want your drum sound to be it could be either. One other function it performs is eliminating/redirecting reflections between parallel surfaces.

and are the grey walls simply absorbtively treated

Again, depending on how "live" you need/want your drum sound to be it could be either.

I assume the panes facing the front of the drumkit are sliding glass doors?

Correct, that is what the design indicates. :D

Any other details to help get this design built would be much appreciated including ceiling treatments etc.

John's design in this instance indicates carpet. Some designs may call for a more hard/reflective flooring (hardwood, parquet, concrete). Again, that may depend on how "live" you need/want your drum sound to be, as well as your budget. If a design calls for a hard floor, it is generally a good idea to have some absorption (cloud) over the area to eliminate floor/ceiling reflections, providing your ceiling height allows for it. Keep in mind the dimensions of a given space and the amount of "liveness" needed/wanted for the source that is being recorded. The acoustics you want for a live drum sound is totally different than you want for a vocal, for example.

By the way: what alterations to dimensions / treatments if any would be indicated (modally speaking) if I can afford an internal ceiling height of 9 or 10 feet or even higher?

That depends on what height you ultimately decide upon. Once you determine what height you will be working with, the other dimensions can be calculated. Hope this helps, Aloha 8)

Thanks Kendale for confirming the internal considerations for the drum booth design. I have settled on an internal height of 2.6M. However, due to the available space I will now have to rejig the configuration by making the 2.550M side longer and the 2.850M side shorter. The available maximum internal dimensions I could fit for each of the sides respectively are: For the originally 2.550M side: 2.90M " " " 2.850M side: 2.30M " " " 1.995M side: 2.25M So basically the booth will be squashed in one dimension, and stretched in the other. I would be extremely grateful if you could advise the ideal final internal dimensions given the above available maximums and the stated 2.6M height. Many thanks for your help as this will finally see an achievable solution to a long-term problem. Thanks again, Wayne P.
