Hey does anyone know where I can buy acoustic foam tiles like the ones here in the Phil?
(http://www.acousticalsolutions.com/images/products/main_sonex_foam.jpg)
The one on top... the dark gray kind. Thanks!
-
hmmmm same question here.... the same surface as the white one, you could but it at any Uratex outlet.. but the grey, black one is more appealing.. san kaya meron ganyan??/
-
insulation 10mm ok na yan, yan ang gamit ko minsan nasa pag control na rin ng sound lalo sa drums dapat moderate na pumalo
-
luminamusic, you know where I can get foam like that? Please give more info. Thanks! :)
-
sa ace hardware
-
sa ace hardware
how much? per piece ba yan o per yard/meter?
-
luminamusic, is that the 12" x 12" foam with holes in it? Kasi I could see any that looked like the diffuser boards in the photo I posted. I don't need insulation foam. I need it to get rid of a problem wall. I've seen a few other substitutes... but I like the way that particular foam pattern looks. I've seen it used in a few theaters here, so i was HOPING it was locally available.

about foams pde ka mag pa customize sa uratex alabang.. yung main plant ata nila yun..
-
naka technic na rin kung papano mo ilalagay yong mga soundproffing gears and acoustic, basta all i know nagawa namin siya sa studio namin, hindi na rin kailangang mag pa customized gastos lang yon, dapat practical na rin, well dito sa amin tested na.

Are the foams from Uratex rated for audio? For such foam to be effective, air has to be able to pass through it. Foam also has to be at least 2 inches thick to have an effect with 4 inches recommended. Foam also does not make an effective bass trap. FYI, the foams in the pic above look like Auralex products.
Here's (http://ethanwiner.com/basstrap.html) an excellent article by Ethan Winer on how to DIY your own bass trap; the only probem is finding 1" rigid fiberglass - this article was printed in Electronic Musician June 1995 (which I fortunately have).

Admittedly, my midi project studio is not equipped for recording vocals or miked audio simply because I changed my emphasis to midi and mostly audio post mixing (and also since I have relocated to my bedroom - impossible to record a band there). I do most of my vocals and/or miked recordings at Millet Jacinto's or even Shinji's since they're both good friends of mine, and they have better mics than I do (AKG C414 for the former and Blue Baby Bottle/Neumann U-87 at the latter). I even recall Millet having the same Auralex foam in her control room; I haven't been to Shinji's yet after the renov.

tama si sir kitc hindi basta-basta yan! i agree
-
yeah mahirap nga ito gawin.. just want to gain knowlege how to acoustic a room.. at least may idea ako.. basically i just want my proposed studio to be comfortable for my clients... kaya for now foam lang muna.. pero ng ka interest lang ako dun sa mga bass traps.. im just wondering sir kitC kasi sa bass trap diba may surface na plywood.. so diba mag bounce parin dun mga high freq? tama ba?? thanks.

I had prepared a rather lengthy reply when I remembered Ethan Winer's site. In a sense, why reinvent the wheel when it's all there? If you go here (http://ethanwiner.com/acoustics.html), Ethan explains the rationale to the where, why and how of bass traps, absorbers and diffusers and how to treat for recording rooms and mix positions.

great site sir kitC! ganun pala yun. hehehe.. kala ko kelangan foam lahat ng room.. at least may idea na ako ngayon panu acoustic ang room...
now i need to know where to get those supplies! heheh..
salamat sir!

Kit, the Uratex foam is for dampening... not diffusion. I have their foam between my walls just to minimize outside noise. My problem is slapback. I was looking at some Auralex stuff in the US... kinda bulky to bring in.
I'm also not too fond of the pyramid pattern. As per my understanding, the dark grey foam I'm looking for (like in the photo with the ||E ||E pattern) also acts as mini traps for higher frequencies aside from diffusing them.
I've padded a few problem spots and it has helped, but Uratex acoustic foam is flat and closed cell foam, so surface is smooth and does generate SOME reverb. It's not like packing foam.
**Another note, guys and gals... please don't just stick packing sponge foam on your walls. These usually aren't fire rated and WILL go up in a flash and emit highly toxic fumes.**
Uratex makes acoustic foam usually for building insulation and echo control... but not to studio specs. It'll do for now... but I'm really after the padding I posted above.

I'm quite aware of what the Uratex is capable of.
Slapback can best be minimized thru a combination of diffusion and dampening. From my experience, slapback is best controlled thru diffusion, however, you also have to identify the specific location where slapback occurs and what frequencies are involved. In a pinch, thick drapes and some well placed furniture will work. You also have to take the vertical into consideration; some well placed carpets will help. Heck, I've even used pillows, a thick blanket and a mattress to control some room modes and oriented myself diagonally to the room walls just to capture a live voice-over session.

mga customer satisfied naman silang lahat, dahil sa pag balance na rin ng sound, kasi lahat sila dumadaan din si mixer, especially yong vocals dapat di rin mag feedback, sa drummer naman may mga iba-iba silang variation lalo na sa stix, yong iba kasi ginagamit brass stick at marunong silang mag control ng palo nila kung kelan lalakas at hindi, about sa guitar amps ok din yong tunog at bass amp, sa ngayon wala na kasing masyadong dinadaan sound kasi na close tlaga yong studio, hindi naman dapat palaging may foam yong lahat ng studio, wala atang ganon hehehehehe, thanks sir kitc again, i think nag research ka talaga ng todo, ganon talaga yon, research lang yan, oo nga pala medyo risky rin yong foam, baka kasi masunog lang yong studio lalo na kung malalakas yong wattage ng amps and then mali yong wiring ng electrical at di kayanin sayang lang yong investment.
cheers

Oh, sorry.. I thought you were really asking about the Uratex foam. :P My apologies.
-
re diffusers, you can perhaps google a DIY project. i know a couple of people who've made them, but it involves carpentry work.

Someone sent me a link to a tutorial on DIY Home Studio Acoustics (http://www.samplecraze.com/tutorial.php?xTutorialID=28). Interestingly, the author used rock wool for building a bass trap which is related to the other thread on acoustic building materials. WARNING: Carpentry skills required. :)

hey guys, basic and most important material in soundproofing is ROCKWOOL and we sell these materials.
this is Fire retardant meaning fire protection for your room.

sir, anung type ng rockwool yung ginamit dito? yung rigid ba or blanket? thanks..

Appears to be the rigid type.

sir thanks sa reply... btw, dito sa link mo.. yung basstrap ni ethan winer dito is rigid fiber glass.. now i have red na mas maganda raw rockwool kesa sa fiber glass.. my question is.. do you recommend sa design ng basstrap na ito ang rockwool instead of rigid fiber glass. thanks in advance again sir!
-
I think the design lends itself to being able to use rockwool. If you do a google of DIY basstraps, you will get a lot of hits on people using rockwool in both rigid and non-rigid configurations, although rigid is a lot easier to cut.
-
guys, meron ba kayo alam na frame for basstraps, sound absorbers kahit hindi kaparehas ng nasa pic.. kahit similar lang na pwedeng frame.. for 2-4 inches rigid rockwool

A few things:
1) Foam, unless it is treated with fire retardant, is very dangerous to put up on walls or ceilings. The old Tasha Records studios in Libis was burnt to the ground in a matter of minutes because the wall and ceiling treatments were all untreated foam. The case of a bar in the US where a band was playing, lighted up some fireworks, got the acoustic foam treatment into flames, and several died.
2) The one that was shown in the picture is from Sonex, not available locally. Sonex is fire-rated and at the same time, has a spray type fire retardant that you have to use on installation.
3) RockWool and Glass Fiber (also known as Glass Wool, Fiberglass, Mineral Wool, etc.) have almost the same absorption coefficients. The difference is the price. Rock Wool is a bit more expensive. Also, their density rating differ. You can get both in 1 inch and 2 inch thickness. Normal thickness used in acoustics is 2". 1" and 2" mineral fibers have differing absorption coefficient. If you want to absorb more LF, go for the thicker one. I have used 4" thick glass fibers to have a better LF absorption and higher abs. coefficient in the HF.
4) In a studio, you use absorption, difusion and reflection to control the frequency response of the room. You compute the RT60 based on the absorption coefficients of different materials. Typical reverberation of studios are .2 to .35 seconds for control rooms and .2 to .7 sec. for studios, depends on how big your space is (volume) and what you want your studio to be used. For spoken word, a short RT60 is preferred. For orchestral, like strings, brasses, and choirs, the higher the RT60, the better.
5) You use bass traps or LF absorbers to control the LF energy of the room. You design these traps to make the bass response in the room tight and punchy. You can either trap the LF energy with big absorptive cavities (these are the real bass traps), or use panel absorbers - combination of wood panels and glass fibers, or Helmholtz resonators, boxes with holes or slats with fibers inside. You just do not put in LF boxes. You have to compute for the room response, other wise, it will just be a waste of money.
These matters will be discussed in our projected seminar on the recording process, just to let you know.

Mga sir.. may nakita akong supplier ng rockwool... http://www.grandharvest.com.ph/Product.html
tanong ko lang is pano ung tamang setup?
concrete wall -> spacer -> metalframe with rockwool -> gyspum board ?
is that ok?
i'm trying to contain ung tunog ko kasi sa drums... mejo naiba sked ko kasi sa work at 8pm na ko nakakarating.. ndi na ako makapractice hehe.
