I have low ceiling as well in a basement so this is usual case for that kind of area

Anyway this guys were helping another gearslut with acoustic treatment for the ceiling above the mix area(mixing cloud)
they said yes,yes,yes, you should it will help truly.
Now my wife and I are going to do this in my office/studio area Monday and Tuesday this coming week(off of work)
going to take my 8 of my 3" acoustic foam panels that are 54" x 54" or 4.5 ft and gluing two panels two together 6" thick and taking care of the first reflection points
and then we are going to take 4 of the remaining panels make two 6" panels out of the team the glue them side by side making a 9ft. long left to right panel that's 6" thick and hang it as a mixing cloud
I already have my front wall done with 48 2" Auralex panels on my front wall well their are glue together making them 4" thick on my front wall
and I have the 4 the Auralex LENRD yeah they are purple ones
in each front wall corner
Well I took 10 of 2" auralex panels and made five 4" thick Auralex panels and place them on my back wall
my wife and I will also be placing 12 of the Auralex MiniFusors that I have stuffed with left over aurelex foam from my last studio setup around the room doing some studying this weekend to see what's the best way to use them instead of just on the back wall
I got all the acoustic foam except for the 54"x54" panels stuff about 9 or 10 years ago when a pro audio music store Mars Music Store was having a closing blowout sell
including my Tascam US-428 audio/midi control surface interface/Cubase VST 5.2 and Casio WK-1800 76 key General MIDI Keyboard workstation lol so I got a really,really good deal
I didn't know Acoustic Foam is not worth it for true taming frequencies in your room
foam does take care of low frequencies
the foam will have to due till Feb. when I'll be going with GIK Acoustics room kit #4
NRC Data Table
You can judge a foam's absorptive effectiveness by studying its NRC (Noise Reduction Coefficient), a single number average of a foam's absorption in what was determined long ago to be the most important range. The federally mandated test (ASTM C423) is standardized to cover frequencies between 125Hz and 4000Hz, but when calculating an NRC, only the coefficients from 250Hz to 2000Hz are used to help alleviate the possibility of testing errors.
All of our foam products are tested at an independent, unbiased acoustical laboratory - the oldest, most reliable lab in the country. We insist on using only the very best testing facility because we believe our customers deserve the most accurate absorption coefficient information possible.

STC Data Table
STC (Sound Transmission Class), is a numerical rating of how effective a material is at blocking the transmission of sound through itself. This rating generally applies to hard materials like rubberized sound barriers, concrete, brick and drywall but also applies to a much lesser degree to softer materials like mineral fiber (although it isn't tested by itself; it's tested as part of a wall system to verify its effectiveness). Virtually every material filters out some of the sound that travels through it, but dense materials are much better at this than are spongy materials.
so long story short yes mwandishi treat your ceiling above your mixing area
when I get the GIK acoustics room kit I'll take all the acoustic 54" x 54" foam panels and make a 12" 9.5 left to right mixing cloud
something like this
thought I would share that with you with going on in my studio environment
and check out what FP Member did with his room sick,just sick
I'm not handy or I'll build my own too..or maybe I'm just lazy either way lol....
