For the floor, try puzzle mats and/or 1- 2 layers of 3/8" rebonded foam (like the ones you see under carpets for cars) then carpet. 


question, alin mas mura sa 2?:)

anu yung rebonded foam? baka alam ko lang ichura nung tinutukoy mo pero hindi ko alam pangalan...

basta usually, gray in color ung carpet na yon. light or dark gray. yun ung carpet na usually ginagamit sa sahig ng mga sasakyan. un din ung mga carpet na ginagamit sa mga cheap na speaker cabinets.

crazy talk yng 10 trays tapos lagay sa wall, :-o liit din kasi ng space nasa attic kame. sakto lang yng sound di na din pala masyado nagagalit yng mga kapitbahay namin

sa proofing, no use mga yun... diffuse lang siguro. pero huwag mo na i-try. mahirap gawin yun.

suggested readings for acoustic principles (so you can get a grip of how sound is produced or travels, entonces, nature of sound):

1) Huber, David Miles, and Robert E. Runstein. Modern Recording Techniques, 5th Edition. Oxford: Focal Press, 2005.

2) Rumsey, Francis, and Tim McCormick. Sound and Recording, An Introduction 4th Edition. Oxford: Focal Press, 2002.

3) Eargle, John M. Handbook of Modern Recording Engineering, 4th Edition. Norwell, MA: Kluwer Academic Publishers, 2003.

Acoustic topics are normally in the early chapters. You don't have to master all the mathematical formulas, just get a good idea how it works.

mga sir tanung lang po planu ko po kasing magtayo ng tracking room na nakadikit lang sa bahay namin. ang plano ko po sanang gawin isang pinto walang bintana nakasimento lahat pati bubong. wala pa po kasi akong nakitang ganun ang pagkakagawa ng tracking room nila ok lang kaya yun mga sir?
yung control room po pala nasa loob ng bahay namin tapus yung tracking room nakadikit sa bahay tapus may salamin lang para makita ang nagrerecord.

studio floor plan wala pa pong sukat

eggtray, fruittray( apples/oranges = looks better ) wont help on soundproofing... diffuser baka pwede pa...

Does this mean pwede gamitin yun egg trays to cut down on echoes? Kaya cguro meron parin gumagamit nito and claim that it still works.

Egg trays as they are made today, do not have sufficient absorption coefficients usable for acoustical purposes.  I believe some people use them for not knowing the properties of these materials and what to use for sound control and tempering.  There is a long thread regarding the use of egg trays in this site and I think, it is our duty to let people know about.  The real danger actually is not in their use as acoustical materials.  It is the flammability factor that is important here. Much the same as foam (especially those without retardant properties - even foam with fire retardant chemicals catches fire real fast), egg cartons can catch fire easily.  Dangerous.

Curtains are quick fixes that I normally advise.  These are used as temporary measures to acoustical problems.  Also, put into mind that they can be pulled down anytime easily if there is an emergency.  Flammable materials like foam or egg trays are normally hard glued to walls and ceiling.  Of course, the better way of doing it is to put fire retardant chemicals on curtains as well.

Curtains and carpets are both absorption materials although the frequencies they absorb differ.  But if you would like the reverberation time of your room to decrease, removing mostly reflections on the high frequency region, carpet or curtain would be okay.  Carpet the floors and two sides of the 4 walls and you will have a fairly decent studio with at least a .4 sec. RT60.

Egg trays?  You never put them on top of one another.  Walang effect yun.  Biro lang yung comment previously.  Never use egg trays, unless you want to be different from convention and would like to show na mayroon kang acoustical knowledge kunwari.

Just think of the extra expense as life insurance. Without proper soundproofing, your neighbors could put your life at risk.

Kailangan na kailangan ko ito. Nagrereklamo ang mga kapitbahay ko pag nagtatambol ako..Kailangan ko ng sound proofing. Eto ang naisipan kong design.

Walls: 5" CHB + 1/2" gypsum board on wood frames. Spaces to be filled with
          rockwool fiber.
Floor: Rubber mats + cheap carpets. (yun mga nabibili sa divisoria). I'm thinking of using dampers for the drum set using tennis balls. Dito ko rin yun nakita. Sa 2nd floor yung room kya sa tingin ko kailangan nito.
Ceiling: no idea
Ventilation: Split type airconditioning
windows: No windows

comments pls...ok na ba ito??. Yun sa ceiling wala pa akong idea. At yun sa mga corners, dapat daw sealed pero di ko alam kung paano.

The goal is cut down on the noise coming out of the room to avoid conflicts with the neighbors.

saito-san,  :-D

where is your neighbor, underneath, above your room, or in a different house and lot?

also, what is your floor made of, concrete, wood, combination?

how big is your room?

@palaka: i saw your previous post.

so your control room is in the house, so presumably that does not have a concrete roof like your tracking room, correct?

you can control echo by: 1) avoiding parallel surfaces (walls, ceiling/floor); 2) using absorbers; and 3) diffusers.

unless you live in a posh country home, remote from all the urban jungle noise, concrete alone may not be sufficient noise insulation. you may need additional layers--walls, ceiling/floor.

i would also recommend double doors to keep noise from seeping into your tracking room. additionally, you will need to treat your room's acoustics, which typically entails curtains, carpets, bass traps, diffusers, etc.

it all depends on the acoustic fidelity you are looking for--and, of course, the inescapable budget.

Yes.  What you will get is an echo chamber.  Put absorbers on certain areas of the walls, ceiling and flooring to lower down the reverberation of the room.  You need to keep it down to .35 to .45 sec.  That reverb chamber will have at least a 1.5 sec RT60, depending on the size of the room.

IMO, in some cases, helpful din ang reverb chamber especially on vocals...lalu na if manipis ang voice ng vocalist...
on SNARES also... ( but the drummer won't opt to record the snares alone...so i use the plate rev for snares... ).
sir mike, regarding curtains, anong tela ang maganda? other than what you've mentioned earlier in this thread? other options...?

can 2 sliding glass doors offer the same isolation as 2 solid core doors?

@peeves24: a 6mm float (plain, common, ordinary) glass has a STC of about 26db. solid core doors may be in the high 20s or low 30s. plus a solid core door you can layer with MDF board and/or gypsum. You can do the same with glass by choosing laminated glass instead, which has a STC in the low to mid 30s, but is more expensive.

But the weakest link, I think, is the seal. It is easier to seal a swinging door than a sliding door. Naturally, sliding doors have "sliding space"; gaps that reduce friction between the moving surfaces. So those would be your natural sources of leaks.

But, of course, it also depends on what kind of noise reduction you are looking for. Some people are marginally less fastidious about noise into the control room than they are with tracking rooms.

And the trade-offs. For my personal DIY SOHO/studio, I traded a bit of noise for a lot of light, at the expense of higher cost (two laminated glass panes on separate, isolated structures).  Good luck with yours.

thanks botbenz, hirap ang limited space e. having a double sliding door will surely make my life better (not to mention the added pogi points to the studio interior  :-D )





background info:

- bongaloo type yung bahay
- 1 spare room and it has 3 concrete walls already. the 4th wall is wood that separates it from the master's bedroom. i will definitely knock it down and make it concrete as well.
- ceiling will also replaced with concrete (abang na para sa 2nd floor)
- separate control and tracking rooms
- isolation level na gusto ko, yung pwede ko magdrums kahit hatinggabi
- mag iinvest sa split type aircon (problema lang 2 rooms yung studio, ducting?)

nice post, peeves!

what software did you use to draft and visualize your design?

presumably, your rooms don't have parallel surfaces. it's tough to visualize when seen from a vanishing point perspective.

are you contemplating the sliding doors between the control and tracking rooms, or between your studio and the living room? if it's the former, i guess sliding doors may suffice. but you'll probably have to mute your monitors (use headphones instead) during recording, so monitor audio does not seep into your tracking room.

you sure you want separate rooms? i thought my 12'x20' studio was small. i decided not to have two separate rooms, well, because 80% of the time, i will use the room as a SOHO--a very quiet one.

you and i are roughly at the same stage of our "studio" builds, it seems. here's mine: http://web.mac.com/botbenz/Music/Blog/Blog.html, which i ought to update, since my design has changed since then.

regardless, you and i can probably use a few tips from master mikep. :D
