Soundproofing question

[remla02]

Mga sir tanong ko lang lang about soundproofing a room, i'm on tight budget guy so hindi ko talaga afford magpa-acoustic treatment sa room ng studio ko, So tanong ko malaki ba tulong yung mga "Office divider" to soundproof a room? isasalpak ko siya sa mga pader ng studio ko, naisip ko kasi ilagay to kesa sa mga egg trays (na alam ko naman na hindi nkakasoundproof ng room), Someone here tried to use Office Divider as alternative soundproofing materials?

Nabili ko yung mga office divider 10pcs iba iba ang size sa Scrap Store malapit sa amin, for P1300 peso.

Eto mga pics:

What's the material of the office divider?

kpg kinapa ko cia sir kahoy yung pinakagitna nya tapos may manipis na foam na naka-sanwich  sa kahoy/plywood.

Parang ganito

Tela > manipis na foam > Kahoy plywood < manipis na foam < tela

Tingin nyo mkakasoundproof to?

[remla02]

Yung kulay violet/blue na yan, Yang yung pinaka-tela, magaspang na tela yan tapos loob nyan foam na manipis din then plywood or kung ano mang kahoy tawag jan hehehe

This would not work for sound proofing.  Sound proofing and sound treatment is totally different.

Pero for absorption it helps dba sir?

it would work...but it would've been better if you used rockwool instead of foam...

Hindi ko po kasi alam itsura ng rockwool, actually itong divider na to kapag kinapa mo hindi mo mashado mafeel din yung foam, parang tela lang din na nilgyanan ng sobrang nipis na foam, majority pa din nung parts is kahoy, pero d ko alam kung anong klaseng kahoy to.

then this is useless even as an absorber. anything less than 4" to 6" thick foam is just a waste of material.

Too thin to absorb frequencies.  This one absorbs "ultra" high frequencies which you do not need in recording or any kind of sound work.  Sorry, you spent on something that is not useable for your purpose.

Office dividers are for offices.

Sir sa pananaw ko okey siyang absorber, bago namin ito nilagay yung room is full of echos and reverbs kapag nagsasalita ka or sumisigaw pero ngayon as in dead sounds na no echo and reverb ewan ko lang kung tama yung term ko ng absorption, about sa sound naman, dbale yung room ko kasi ang kabila nun is the studio room na, as in kitang kita sa bintana, ang ginawa namin tinakpan namin ng divider yung bintana, 80-90% ng sounds ay anablock na from the studio to my room, ang pagitan lang nun eh hollowblocks lang po, Does it mean naka-swerte ako?

eto po after namin ikabit yung divider yung kabilang side nyan eh room ko na at nung nagpapatugtog ako sobrang d ko n siya marinig.

syempre, compared to egg crates, it is an improvement, but as mikep said, it is too thin to absorb frequencies. isa pa, since it has  wood backing, it is also acting as a reflector back into the studio. you may have flutter echo problems as a result. don't say we didn't advise you.

Ah okey thanks sir =)

Your bintana is the weak link for sound to transfer to another area and since you covered it with your office partition, definitely there will be a reduction of sound being transmitted.  But it does not mean that sound has totally been blocked.  It is like adding a piece of 3/4" plywood into your bintana.  Your divider and a 3/4" plywood would have the same transmission loss or TL.  As an absorber, like I mentioned previously, it does not help out in tempering the frequency response of your room.
