which ceiling design for a small room with drop ceiling?

pilldriver · 12th April 2008

hey there

my "control room" ist 5m long and 3,5 m wide.

the backwall ist treatet with hangers (best improvement, thanks to john sayers forum

)

i have a drop ceiling (2.3 meters) with homosote plates.the problem ist they dont absorb much low frequencies , so i have a very disturbing mode @148hz.

i have angled for experiments the ceiling above mix position and it seems much better.

should i go for "expansion ceiling" with a "V" or only going higher from front to rear.....or maybe compression ceiling

...or just place some aborbers(which i dont really like)

cheers

I think absorbers is your best solution.

thanks for suggestion,

i also go for absorbtion now.i will replace these tiles with some fabric.
does it make sense to angle the ceiling for different spacing of the fiberglass layers?

Both would be the ideal. Angle+cloud.

Angling a drop ceiling is mostly pointless. And angling the absorption isn't useful either. Once the absorption is in place the reflections are stopped, and that's the main goal here.

here is a link to some pics to see what i mean Mainpage_Sjoko ( go to UPDATE3 and the last pics) ...i think the goal was to have on the front and rear of the ceiling more absorbtion to the low freqs. so the absorbtion becomes more broadband.

i want to make the same just with another framing

what you guys think about that?

Are you talking about angling a rigid ceiling, or angling a suspended grid only?

hi ethan,

a suspended grid only!

Then just leave everything flat.
