@palaka: curtain absorption largely depends on the type/weight of fabric and the distance to the wall. google "sound absorption frequencies curtains".
bali yung curtain ko pong nabili makapal siya tapus 2 layer po yung ginawa ko. sir tanung ko narin po anu pong sukat ng ganitong diffuser pag mag gagawa ako ng diy?tnx

i forgot what your reference diffusor is called, but it looks like the inverse of the skyline diffusor, which also seems easier to make.

most of the diffusors i have seen in the rear end of studios are QRD types. google "QRD diffusor calculator". some calculators can tell you the diffusion frequencies based on well depth and width that you specify.

but if you build one like the one you have referenced, let me know. i'll pay you to build a few for me! :)

yes! i think there are commercial diffusors (auralex?) that are made of a synthetic material (plastic, resin, etc.)

but most of the DIY skyline diffusers i have seen (google "skyline diffuser DIY") are made of wood. in fact, i planned on doing the same and, in fact, bought several *dos por dos*, which is really more like 1 1/2" x 1 1/2". plane it to square it, then cut them to length, according to the diffuser calculator. maraming mapaggagayahan sa internet. good luck!

The Skyline Diffuser is also known as a three dimensional diffuser.  I have those in my vocal booths, constructed by my carpenters.  A little hard to do the reason why I stick to mostly QRD or Schroeders.

In the case of your church, what you need are ceiling diffusers and back portion absorbers, side wall reflectors and diffusers.  I just designed the new Bread from Heaven church on Shaw blvd near the Glory (?) supermarket.  The old ceiling diffusers that were once in the old church were the same ones used, including the reflectors and diffusers.  I just added a few to make the RT60 work better.  If you have time, you can go visit them to have an idea.

You need to make some computations and you should know where to put the treatment otherwise your efforts and money will just be wasted.

Hello!

A few questions lang mga master:

Im currently building a studio in Quezon city and I'm having a hard time looking for a glass supplier that can supply me with 19mm and 15mm thick glass,
can anyone refer someone or a company for this? (My Engineer friend whose helping with the design/construction told me this would be the ideal thickness BUT:

Sub-question: would 12mm(Live room) + 10mm(Control Room) suffice? the size of the glass is only 3x4ft.   

ALSO, I'm looking for someone to install an "in-the-wall" mic and headphone wiring/rig for the live room, is there anyone in philmusic who can do this?
I'm not really good at soldering :cry:

SALAMAT PO IN ADVANCE.

For my home office/studio, I bought 9'x4.5' laminated glass from Glasstek in Kapitolyo, Pasig. If I recall it correctly, it was 15mm thick. They can custom-cut smaller sizes, but not make it bigger than what I got.

Am no expert, but your 12mm + 10mm combo would be better served by laminated glass, or at least tempered glass. And, of course, spacing in between will also significantly help.

I have soldered a ton of stuff in my life, but keeping the lines RFI-free is the bigger challenge. I too bought in-wall mic/line panels, but I haven't gotten around to completing my build, so you're better off with someone with real experience. :) Good luck.

Thanks for the referral and quick reply!

Unfortunately, they don't have anything above 12mm in thickness :cry:,  THEREFORE, I'll go for the 12mm nalang.

Followup question mga sir:

Should i use 12mm glass(Live room)+ 8inch gap+10mm glass(Control room) or should i use 12mm on both sides nalang?

I trust my friends' design, but due to availability and schedule, i can't accomplish his 1st world design(Unfortunately). My contractors/workers are having a hard time as is constructing the double walls and isolation. Do you guys think 12mms are enough for this? :? 

Thanks in advance. :-)

thickness/density affects resonance frequency. so using glass of different thickness results in different resonant frequencies, which is generally desirable. even for multi-layer walling, that is recommended. in my case, i plan to use a fiber cement / gypsum combo. different densities, different mass, different resonant frequencies. recommended! :)

Hey BotBenz, if you decide to get rid of the Greenglue I'll take 'em off your hands! (assuming they're still somewhat ok) email me a (superdiscounted) price at findail@mac.com  :-D
this thread's email notifier doesn't seem to be working; i don't get notified of new posts. sorry for the late reply!

@Findall: my studio/music hobby was sidetracked by another hobby, including the budget! :D so i have three cases of green glue from about 9 months ago, and i sure hope they haven't coagulated beyond use! between your reminding me and mikep's tip on sourcing Kinetics' hangers locally, i ought to get back to completing my home studio/SOHO--this year!

if the green glue *expired* (i don't know if it does) beyond usability, i will probably just skip it. my poured concrete outer room seems to have attenuated noise sufficiently.

Question lang about practical soundproofing. I have no experience with soundproofing whatsoever.
My family is moving in to a condo unit and well, i dont want to part ways with my acoustic upright piano (its a personal thing I really dont want to have a digital piano as my main practice keyboard) And I'm worried about making too much noise to bother neighbors. I usually play night-time after work when most are sleeping so if ever gusto ko sana di talaga maririnig ng neighbors ung piano

Issue
1. My family does not want to "uglify" the living room of the condo. So studio soundproofing like egg cartons/ corkboards are a no-no. The best I could have for the room are carpets, wall rugs (to the point na maganda pa rin siya tignan sa wall. i cant plaster the wall with rugs), upholstered seats/pillows, curtains I guess and the like.

So ung main question ko lang I guess is if enough na ung ganitong set-up (considering a piano wont be excessively loud anyway). I cant do anything but to put a sound-absorbing foam on the back of the upright piano I guess (I read somewhere that putting auralex foam on the back of the piano works to some degree) But aside from that, wala na. Kasi pag di gagana to I might as well save up on moving cost and just send our piano back to the province in the meantime.

My suggestion would be to sell the piano and get a decent digital piano...a professional one, not some cheepo keyboard...something like a Yamaha CP300 or the new Yamaha CP5 or CP1 (though with this one you'll need a pair of small powered speakers). This way you get the nice weighted piano keys but have the option to play at night through headphones. Also save some space, which is kind of a big deal in a condo. Save yourself the hassle and headaches and complaining neighbors/family.  :-D

@Findail

I'm actually also considering that. (For that option its either the CP5 with the wooden keys or the really really attractive Korg SV-1). But the hardheaded traditionalist in my head is telling me to keep my acoustic upright haha.

So now i'm really considering soundproofing muna (on the restriction that its not going to make the living room look like a studio). but if the cost is going to be as high as the retail price of a CP5 or an SV-1, I'm just going to go digital nalang since I could always go back during the weekends just to play if I really miss my piano.

So there. Any suggestions? Or if you have experience in the issue, do you think my set-up will work na?

It really depends on the condo I guess. The condo I'm staying in now, although concrete walls et al, has a horrible main door and windows, soundproof-wise. And we're not allowed to change the door, as stupid as that sounds. Windows, well, they have to approve if I want to change it for the better. So you'll probably run into dumb things like that. But I suppose you can keep costs down if the condo is built well enough. I'm not an expert, but do know that sealing every crack in the door is pretty damn important, as well as a solid core door. And if the windows are fairly new, like the pvc Kenneth&Mock or Duralco, they're pretty airtight if the glass is thick enough.

Might be a good idea to describe the condo in detail, like where the piano will be and what the walls, doors and windows are like. Then the experts here can probably give some better advice. It is doable though.

A great digital piano is the way to go nowadays.

Many models have 88 hammer action, weighted keys, built-in speakers, USB ports so you can easily connect to a computer to record your performance or compose music with a DAW, headphone outs for quiet practice and listening, etc., etc., etc.

Check out the Privia PX330 or PX3 (from Casio) line....best bang for the buck.

If money is no problem, then the Roland V Piano, Korg SV-1, Yamaha CP1 are your choices. The Yamaha CP1 is on my wish list  :-D

Google them.....

@Viscant: I never really liked weighted hammer action keyboards. I usually preferred semi-weighted ones coz I find weighted actions springy and well, the keys dont return back to the natural position as fast. But I tried an old yamaha weighted digital (dont know what model) at a music school along libis and was surprised to how good it actually feels. I'm actually considering one right now because of that. Maybe I just need to break the keys in before judging. I usually just try to play the weighted keys for a short while on the music stores kasi. but going back to the main topic

@findrail:
Well, i dont have the exact layout of the condo pa, and i didnt know it needs to be that detailed. but thanks anyway. I'll try to ask people here again if I get more info

skin, pwede yan, pero im sure you may need a lot... sort of 3layer ( sandwich ) + air gap + another layer again.
If you need a lot, it means more money... Gypsum Boards will still be 50% cheaper...

what kind of fiber is that? wood? glass?

Cement fiber board.  Effective kaya?  I just don't know kung didikit ang asphalt sheets when heated sa cement fiber board.
