Urgent Help

Hey I am Laura !

Its' great to experienced lots of resources on such a important topic "Studio Design and Acoustics" Thanks to the Founder.

I have a very small and room with identical dimensions for my drum tracking, i was initially thought that i just needed a room to accomdate my drum thats all but after going through lots' of info on design topic i found that all what i have done was bull shit.

My room is around 108Hx114Wx110L ", i have a hardwood floor and sheetrock ceiling with mineral wool insulation, i would like to record my drums with my tiny digital setup. What type of treatment it required? Help me if you can.

Laura - click on the John Sayers Productions logo in the top right. Then click on The Recording Manual. Then look for absorbers ansd read up on them.

Well i have read your manual (Great Text "*"), due to the critical size of my room my major problem is to resolve 62 Hz, 124 and 186 ... must be i have to use some broad band absorbers. ny opinion?

laura

[John Sayers]

Laura - it depends what sort of drum sound you want. Do you want it tight or loose, live or dead. The frequencies you mentioned are low-mids which is what you'd expect with the treatment you've got now. The insulation abosrbs down to around 250Hz tapering off as it goes. You need an absorber for the low-mids which you can do with a slot resonator.

Go to my main page and click on Wall Units.

i have sketched a bit, wonder if it works.....

laura

[John Sayers]

Yes - that's ok - you don't need the left absorber though as you've paralleled the walls again. Try with two to start with.

You could put some straight insulation on the other walls.

is such a tiny room 108Hx114Wx110L for drum recording. I am intended to resolve these frequency 62 Hz, 124 and 186Hzs using slot resonator, i already have a wooden floor as a reflective surface. is there nything more to be taken care. i am planning to refurbish it soon so a bit concern for proper tratment.

[John Sayers]

Laura - you could put some of ethans bass traps http://www.ethanwiner.com/default.asp on one of the walls alternating with some high frequency absorbers. You must bring down the reverb time of the room or it will sound boxey.

What's on the ceiling??

cheers

[laura]

well i was reading some resources on net and found that my ceiling definitely treating some bass frequencies as i have a semi peaked ceiling in which two parallel sides are angled. it is ike a hut ceiling but the centre it not totally peaked. i am having two horizontal corners on ceiling which are giving me 19" air gap and filled with 3-4" mineral wool insulation.It is finished with sheetrock. I think having wooden floor is preferable in drum room as its' a reflective surface.

Hello John!

i think i must put ethans bass trap on the left side of my room....very confused what to do. Help me out.

[John Sayers]

I'd go without anything on the left wall except insulation, add your two slot walls and see what it sounds like.

cheers
John

[laura]

so it is final to put two wall as slot resonator tuned for 62 Hz, 124 and 186 frequencies, left wall with just insulation and a wooden floor. I think by such combination i get some live enviornment for my drum tracking.

love

[John Sayers]

laura - the moment you put in those slots you stop all the parallel walls and those frequencies you are concerned about go out the window.

cheers
john

[LAURA1]

fairly speaking, i cant get what exactly you are trying to taken care of.

[John Sayers]

Ok - what you have now is a room with sheetrock walls and ceiling and a reflective floor. The frequencies you are concerned about are probably related to the parallel wall surfaces.

What I'm proposing is that you build two slot resonators that are angular, thus removing the parallel wall factor plus they will absorb the low-mid frequencies. (150Hz - 500hz.) Whilst they absorb the low-mids they also reflect or diffuse the high freqencies.

Next by putting insulation on the remaining walls you will absorb the high frequencies down to meet the low-mid absorbers thus bringing the total reverb time of the room down.
