I think I have to buy a rather large fire extinguisher.

Kidding aside, YES, you should.  You are in a pretty "flammable" place.  Just make sure nobody smokes, lights a candle or play firecrackers or fireworks.  Also, watch out on your electricals - lights, conduiting, wires.  Just be on the look out.

Well...I did look around. Uratex has Acoustic foam products that look like the convoluted bedding foam, except it's flame retardant.

But it costs an arm and a leg. Oh well.

Well Bryan, to give you an example of the math I made for a properly soundproofed (but not yet acoustically treated room), the area to be soundproofed was 13' X 18'. Gypsum board costs about P300+ for a 4X8. Together with its fittings and still without the labor and the fiberglass mat "sandwich" that I forgot to factor in, the gypsum boards and mounting hardware alone cost P15,000 . Around that ballpark as I remember it.

ako naman 7 peace of rockwool, for sound absorbers, pati fiberglass for bass traps, and kahoy, nasa more than 10k na! hindi na ako ng palabor. ako nalang lahat gumawa.. kala ko dati aabutin lang ako ng 8k. pero grabe....

wah.. :cry: ang mahal. how about kung room with in a room-hollow blocks. typical na maliliit na apartment ngayon. pwede rin ba yung ganun? mas mura ba o mas mahal?

mejo noob pa din ako sa soundproofing and acoustics kaya nga aattend ako ng workshop ni sir mikep. pero tingin ko mas mura magagastos mo kung concrete na yung walls mo.

... and mounting hardware alone cost P15,000 . 

Mura yan.  I was thinking more like PhP 150,000.00.  I use apat hangang limang patong ng gypsum for walls, plus, double metal studs, glass fiber inside, grounding, etc.  If you wanna do it right, that's the way to do it.

Hollow blocks on floating floor?  That's too heavy.  You have to have a slab floor to support that, plus heavy duty floor acoustic isolators.  Millions!  No joke.  Unless necessary, forget room within a room isolation technique.  Unless you know how to do it.  Very expensive and very complicated to undertake.

sorry for my ignorance.. pero di ba pwedeng magtayo ng isa pang pader na nakadikit sa existing pader. wala talaga akong alam sa construction eh. ano po yung floating at yung slab?

Dude, to make a long story short, you need metal studs and metal tracks like these (which measure 2.4m or 3m long):



Then, you need your insulating material (ie rockwool or fiberglass).  I prefer 60kg density 50mm rockwool slabs that come in 0.6mx1.2m sizes. 

You also need gypsum board.  They come in 1/2" and 3/16" but I prefer the 1/2" slabs.  They are sized at 1.2mx2.4m. Doubling or tripling the  boards works much better. 

For your tools, you need a putty knife, power drill, a riveter, and also, you need some gypsum plaster tape, rivets, gypsum putty and gypsum screws (they look like wood screws, only black in color). 

To make a long story short, you need cut and rivet the metal tracks and studs to make metal frames sized at 0.6x1.2m.  You have to mount the frames to the celing and floor against the concrete wall) where you shall stuff your insulating material in. The gypsum boards are stuck to the metal studs using a drill and the gypsum screws.  Some say it would be best to put some foam tape on the studs where the screws shall be drilled.

The concrete wall will be the innermost layer, the rockwool/fiberglass as the middle layer, and the gypsum board as the outermost layer.  Sa madaling salita, GYPSUM/ROCKWOOL/CONCRETE WALL sandwich.

You can do that, Hollow Blocks+ Air Gap (about 2 inches) + Insulating Material (to control resonance) + Hollow Blocks, but if you are in the second floor, that whole thing is very heavy.  It will have an effect on the building structure.  The better way is doing a sandwich wall as Skunkyfunk has suggested.  But make sure the second wall does not touch the first wall, otherwise you will have a short circuit.  Vibrations from the first wall are transferred to the second wall.  Your sound proofing will be useless.  I normally use acoustical rubber or neoprene mounts to isolate walls and floors, and acoustical ceiling isolators for ceilings.  I had these done based on my design.  You can buy these locally but very expensive as they are imported.  Basic Machineries, Youil and Mason are some of those who carry these products locally.

BTW, I would normally put a Farraday cage, grounded, to keep RF from getting inside the room.  Yes, it has happened lots of times when everything is well insulated, then RF, especially with unbalanced connectors.  A cage is a nice solution aside from using everything balanced including your power.

Metal mesh with copper strap or thick wire placed on top and under all over the entire cage.  Then, sent to ground.

Terms you will commonly see:

RF - Radio Frequency
RFI - Radio Frequency Interference
EMI - ElectroMagnetic Interference
Faraday Cage - a metal shield encasing an object or room to prevent RF or EM intrusion. Most common indication of RF intrusion is when you hear radio station signals from your gear especially if you're situated near a transmitter.

Practically anything metallic given the right conditions. Ever heard about the tooth filling that could receive radio signals? Dentists used to use amalgam, a metallic filler for cavities before ceramic and resin-based fillers became the norm (something about mercury in the amalgam led to its discontinuation). Anyway, some guy complained about hearing music in his head and what they found was that his amalgam filling was acting as a radio receiver! Look up cat's whisker diodes and you'll know what I mean.

The same diode principle sometimes happens with audio gear. In my case, it was crud developing on one of my 1/4" cables. When I plugged it into my synth, I could hear faint radio transmissions from a nearby FM station - I was wearing headphones at the time. The oxidation on the 1/4" jack acted as a diode.

Anything that has coils of wire in it can also generate RFI and EMI, transformers and flourescent ballasts, for example. Try putting a single coil pickup near those and listen to glorious 60 hz hum coming from your amp.

Unbalanced lines are usual culprits, especially if your happen to be very near a radio or TV transmitter.  AM and over modulated FM stations give out a lot of RFI.

you can buy those foam sa mga uratex outlets.. pero like masters here said, hindi siya ganun ka effective katulad ng mga acoustic foams talaga like auralex.. www.auralex.com.. and yung mga ordinary foam can be fire hazardous.. better use, fiberglass or rockwool..

mga master,    dami na ako nabasa tungkol sa pag soundproof ng walls..how about flooring... im about to rent a commercial space for my planned band rehearsal studio.. it will be on a second floor.. 1 foot yata ang kapal ng concrete nung flooring nun.. same principle din siguro ang pagsoundproof ng floor and wall,, pero sa materials same din po ba?(e.g. gypsum board, ok lang ba kung yan ang gagamitin or may mas appropriate na alternative)..
tapos yung isang side ng wall (yung front view mula sa labas) ay glass.. as far as i have been reading sa mga articles, mababa ang stc rating ng glass compared sa 8 inches na concrete.. how do i treat it?.... thanks thanks thanks
