DIY Acoustics and Soundproofing Thread

[bakit?]

so newbie quetions time!

i am starting a rehearsal/recording studio.im interested in learning more about soundproofing/making my studio better  diy.well heres what i need:

1.suppliers

2.info/advice on which cheap materials to use.,

3.studio designs that you have that i can copy(hehe)

salamat mga sir!

pm na lang or text(hehe) 09166829291

Sana makatulong...
ganito gamit ko sa isang project ko sa binangonan

para sa acoustic naman, nilalagyan ng fabric yung acoustic board para di mag bounce ang sound

[mikep]

Sorry to say that putting fabric in any acoustic treatment will not affect the absorption coefficient of the treatment unless the fabric is backed with rubber coating.  In such a case, the acoustic treatment will become a semi reflector.  An acoustic tile covered with fabric will have the same acoustic property, i. e., absorption coefficient and would affect mostly high frequencies.  Putting this type of acoustic treatment in the entire room would make the room boomy and will lack high frequency response.  It is best to place acoustic tiles in the ceiling installed type E, that is with an air gap above it, normally held by T runners.  FWIW

i will keep this in mind  (for acoustics)

as an architect i never really designed a music studio before, the intention was to help 
as for ceilings, i couldn't agree more  ,  been using the said materials/method  (well mostly for meeting rooms, A/V rooms, convention halls)
i just know what you mean 

[allhands]

Does anyone know where I can buy industrial/sound attenuation curtains or mass-loaded vinyls?

[mr. trigger]

Share ko lang po yung rehearsal studio ko thanks

mr trigger ano ginamit mo sa mga panel sa wall? thanks

[straightwire]

yung studio namin has solid wood door at the front with the usual carvings ung parang pinto ng bahay ,ung back door I think 1/4 plywood front and back pareho silang nag vibrate pag may nag pa practice  and maririnig mo ung nag uusap labas pag dinikit ung tenga sa pinto ,balak ko pinturahan ng rubberize undercoating paint ung ginagamit sa kotse and then saka ko babalutan ng rebonded foam tapos cover it with carpet .Magiging effective kaya ung undercoat paint na gamitin sa mga pinto to lessen the vibration.
   Or recently may nakita akong parang lawanit na around 1/2 inch ang kapal mas ok kaya ito na gawing pinto

hi guys. i am asked by my land lady to transfer my small studio to a bigger place upstairs (little restaurant below). I am into recording and rehearsals. my big problem is, the walls are just double wall with 4 sliding windows on its sides. I'm planning to make a wall for the booth. I'm currently putting insulators on the windows and put seals. The room also have 4 doors. I mounted those foams that are always put under the carpet. Then a carpet after the foams.

Is it okay? the sounds coming from the vehicles can still be heard inside. any advice? tight budget here. Thank you.

[palaka]

mga sir ba ka may alam po kayong supplier ng rock wool patulong naman po.salamat po

[brownbread]

finally na kakita rin ako ng thread para sa sound proofing
back read time
salamat dito

[brownbread]

nasa page 4 na ko sa ka-backread
at may na basa na ako tungkol sa egg tray


actually sa rehearsal studio ko egg tray gamit
di talaga ito nakaka-soundproof kung hindi pang tanggal o pang kaunti ng vibration at static sound sa studio
hehehe

laki ng gastos sa sound proofing

[Xelly]

laki ng gastos sa sound proofing

+1
And pwedeng masayang yung malaking gastos kung hindi ito mapag-aaralan

As I mentioned, the rehearsal room we use is a converted garage, with dimensions not ideal for a studio.  The ceiling is low, for instance.  The air-conditioner, storage cabinets, and so forth also restricted where we could place the drums and amps.  Noise insulation was not an issue, but room acoustics was.
 
The biggest problem was what seemed to be a strong room mode.  There was one note that, when I struck it on the guitar, was much louder than the others.  If memory serves, it was the E note on the 5th string.

I didn’t know of this forum then and would have asked advice here. I am impressed by the amount of expertice shown by the contributors here and their generosity in providing advice. The good thing though was that I had friends who were into acoustic treatment, and they provided free help.
 
A friend came over with a device that he plugged into the studio PA system and which then generated and analyzed different types of noise, some white noise, some loud ones.  The device confirmed which was the dominant frequency in the room, the frequency that the room tended to resonate with or emphasize.   Here is a photo of my friend with the device in the studio, before we applied any acoustic remedies.  That was several months ago
.


In any case, we went ahead with recommended acoustic treatment, put absorbent panels on the ceilings and some walls.  These made a remarkable difference in the room.

I’m just sharing my experience and hope that will benefit others building a home rehearsal studio.  I’ll bring MikeP over also, as I am sure he will suggest where we can improve things.

WShad, is that Martin?  Looks like him.  Regards.

[botbenz]

WShad, is that Martin?  Looks like him. 

Exactly what I thought. But the last time I had dinner with Martin, he looked even thinner. Must've been a recent birthday indulgence.

Just chimed in, after years off this forum. Glad to see master mikep's still dishing sound advice in spite of the looped questions.

[Wshad]

Yes. that's Martin.  We had to treat the walls and ceiling after that session; the dominant note evened out and the sound improved dramatically.  Our bass guitarist said she could hear everyone.  The studio still looks the same since you played there last, Mike, but the sound is a lot cleaner to my ears.  I am sure you can suggest more improvements, so come over.

[mikep]

Will pass by when you guys jam sometime. Let me know when. Regards.

Martin is my friend too...

I know that a real-time analyzer (RTA), test tones, reference/measurement mic, and maybe sound pressure level (SPL) meter are needed to measure room response. Pink noise is one of the test tones, for sure. Measurements should be taken at different listening locations in the room. What is the step-by-step procedure?

I understand that a flat response is not necessarily the desired room response. Is a smooth response more important to achieve?

Also, I am very interested to know a quick and easy way to measure RT60.

 

[Wshad]

I'd be interested, too, Tarkus.  Maybe we can have a workshop or visit and disuss studios informally.

Ours is a rehearsal studio, and we don’t record there, so perhaps the concerns are simpler.  The principal goal was to have a clean sound for everyone and for everyone to hear everyone else.  With electric guitars and a loud drummer, that was a problem.  We also had that dominant note.
 
The room dimensions were not good, and windows and cabinets limited where treatment could be placed.  The compromise was acoustic panels on the ceiling and one wall, and a few standing panels.  The improvement was dramatic, though, and even with the theater system became clearer and sound placement more accurate; That bonus was a surprise to me.  The treatment can be seen here.  So far it works, but I am sure we can improve it a bit more.

You have to have an SPL meter or computer program capable of measuring RT60 and RTA.  It will be nice if that system is capable of doing MLS response as well so you can see the distribution of the various frequencies and the room modes in 3D or 2D waterfall.  I use several meters and programs and I have one that comes out with tone bursts and it gives you the RT60 on each of the 6 frequencies from 125 hz. to 4 khz.  You need to feed tones or white or pink noise into a sound system.  The RTA or program would receive or read the room response through its microphone, and all the details you need are shown for your analysis.  The important thing is the analysis of the result which can give you an idea of how the room sounds.  The success of the room analysis is in the interpretation of the room measurement.  Then, you either do an electronic correction of the system (not the room) or an acoustic method where you add low frequency absorbers, diffusers or reflectors.

ask ko lang mga master...

im planning to fix my music room. (concrete walls, floor, ceiling and double doors)
ano maganda gamitin para ok yung sound sa loob di boomy and also minimized din ang sound sa labas..
im using this room for rehearsals and also recording.. I need advice for its improvement
im currently using egg tray foams sa walls and mango trays sa ceiling. however, i want it to look neater.. any suggestions? pls post your replies or send me a PM

thanks!

yup, for your needs, backread.

but if you ask why you must backread:
* egg tray foams and mango trays don't work well for absorbing boominess;
* minimize sound into and out of the room, you need mass—lots of it, and not the kind you hear on sundays.
