First Glimpse Of My Stuido !!

[Deshusingh]

please drop-in some insight guys !!

[Tom Higgins]

Firstly, well done Many here will agree that acoustics is the most important factor in a studio

Most important thing is how does it sound?

[Tom Higgins]

And where did you get the traps from, or are they DIY?

Yes, they are all DIY, i paid the carpenter and got them constructed. Though the construction process was hectically slow.

Today, we finished the control room ceiling, but to my dismay, flutter echoes are still arising between ceiling and floor. i need to stuff absorbent, between the panels, to cover up the untreated surfaces, you can see untreated surfaces in the photographs here.
My control room is in the ratio of 1 : 1.21 : 1.41 with the dimensions of 11.57 foot x 14 foot x 16.31 foot (H x B x L, respectively)

How do you know the flutter echoes are between ceiling and floor? The walls look a lot barer than the ceiling..

Because i can clearly hear them, coming from above my head, from the untreated space in between the panels !!

When i clap my hand, while standing nearly at the center of the room, then they are concentrated over my head. and if i move to the back or front wall the flutter echoes shift to the untreated space between the bass traps !!

[AnthonyRochester]

Hmm, I wouldn't rely too much on direction perception to judge what is causing the reflections. What treatment do you have on the walls? Are they parallel?

[Tom Higgins]

Yeah, have a look at treating the walls.

Here's another construction thread:
Small Control Room Build

You could do similar treatment on the walls (albeit that is in a CR). And put wood slats over it if it's too dead.


I'm trying to find another thread where they put up panels in the live room where they could be reversed (one side absorptive and one side diffusive)

Hmmm.... Are you allways gonna wear pink trousers...?

yes, the walls are parallel, hard brick work, plastered coated, concrete ceiling and concrete floor !!

The wall treatment is still to come, all the panels for the walls are made from 2 inches thick rock-wool, density 96 per cubic meter. (i do not have any data regarding the absorption coefficient, the rock-wool slabs are local made, and the manufacturer do not have any data !!)

But i am not sure, weather treating the walls will stop the flutter from the ceiling !! though i have to treat the walls anyways !

Thanks for the link, but i know, what to do with the walls, i am just talking about the floor ceiling echoes ! How to control them, is still i know, but i am just concerned about, to do something extra with the ceiling ;-)

You might want to wait until you've treated your walls and make another assessment then.

Yes definitely, that's very true.

[Deshusingh]

Today (may 16, 2012) we cannot proceed with the fixing of the wall panels as we had power cut the whole day.

[Deshusingh]

The panels are of the size, 4 ft x 2 ft x 4 inches. These panels show the broadband absorbers. My broadband panels consists of 2 inches of bass trap and 2 inches of mid frequency absorbers ,both incorporated in the same design !
one side of the panel is covered with 3mm plywood, and the other face is covered with cloth ! The face you are seeing in the photographs is the mid-band absorber, the bass trap is on the back side of the panel !!

[Deshusingh]

The wall panels are done for the South wall of the Tracking room.

How's the room sounding as you add treatment?

The overall Rt60 has gone down, it sounds much more compressed now, no bass problem is evident by singing or humming (no musical instruments are tested yet). Claps and singing at loud volumes, still disclose the flutter echoes !!
The severity of the flutter echoes, is much more diminished now as compared to, before adding the wall panels. Room sounds bigger that what it is !!

[Deshusingh]

North side wall is completed today. A panoramic photograph show both the walls.

[Deshusingh]

I am posting three waterfall plots. The first one is done with both the speakers playing, second one is done with the left speaker playing at its left position, and the last one is done with the single speaker playing at the center of room. speaker distance for all the measurements is at 51 inches for front wall. I am concerned about the serious dip at around 148 hz. My room is treated with 24 bass traps, going right till ceiling ! please help me to control it.
some fast replies please !

additional data:

1. Monitors = Sonodyne SM50AK
2. Cone size = 5 inches
3. Frequency range = 70Hz to 22kHz (+/- 2dB)
4. Usable frequency range = 60Hz to 25 Khz (-10dB)

Monitor Spec - "http://www.sonodyne.com/product_dtls.php?product_id=108"

Are they panel absorbers? Have you tried straddling them?

Have you tried superchunk/soffit-type bass traps in the corners (wall-ceiling)?

please check out the bass traps in this photograph

Painting my diffusers, gave me a nice high frequency reflection bounce back, and they sound great with that extra content. In other words they sound much more balanced now.

Did you build those yourself? And if you did is there a calculation you used to determine the dimensions of each piece of the diffuser? I'm in the middle of treating a room myself and am looking for a soundly designed set of diffusers. Pun intended.

yes, i gave the dimensions to the carpenter i hindered, and he in turn got them ready for me. The Calculator i used is "QRDUDE". Here is the link QRDude: Quadratic Residue Diffuser calculator.
All the best for the treatment and happy diffuser building ;-)

[Deshusingh]

The painted diffusers got installed.
