thank you sirs, eto kasi yung plan ko na room size, 19'x10.5'x9' ,4 walls are going to be concrete, ceiling niya marine plywood lang, or pwede gypsum? construction will start next week hopefully.
anyway, ang ginawa ko sa computation concrete lahat para mas simple, pero 1.9ms ang nakuha kong RT, or mali computation ko? heheh pag lalagyan ba ng drapes, reflectors at furnitures at siempre yung mga instruments at amps malaki ba ang mababawas sa RT? aabot na kaya ng less than 1?
ano din kaya magandang gawin sa ceiling?
BTW overpriced ata ang gypsum dito sa Bulacan. 12mm 6'x8' = P450
Yep, concrete all around, then gypsum ceiling and cement floor will give you about 1.9 seconds. Parang simbahan, plus the room will be more towards mids a lots of lows. Maliit ang kuwarto mo.
If you intend to place drapes, drape mo all the walls with rods so you can adjust the reverb time. Almost like a variable acoustic system. Use medium to heavy drapes. Your instruments and sofa will not affect the RT60 much. You need 25% of the total surface area treated or affected to see (hear?) a marked difference.
For the ceiling, put reflectors or diffusers of varying heights. This one is a little tricky. You have to know hoe to design these. Poly cylindrical diffusers are easy to make; or you can possibly construct triangular diffusers and place them all around. Search the net.
For the floor, put area rugs. The thicker, the better. Place one where the drums will be. Put one also underneath the area where the singers will stand.
Howe about your air con? Window type?
How about your sound proofing? Are your neighbors far from you? Your cement (CHB) ands gypsum board ceiling will not be enough to stop the sound from coming out. Better put 2pcs. 1/2" gypsum as ceiling. Do not punch holes, i. e., pin lights in it. Better to use track lights for lighting.
Do not put the drums in a corner. You'll add extra dBs in the sound. Place it in the center of one wall of the room where the low frequency is almost null. Same with your bass amp. Never put any amplification in the corners of the room; except players or personnel. Good place to put the keyboards but put the amps away from the trihedral area (corner). Put the monitor speakers underneath the mics to avoid feedback. That is the null point of the mic so you prevent it from picking up sound coming the monitors.
So, 'yun. I'll send you my professional fee billing later. Hindi, biro lang.
Good luck in your project.
