I did some research.... found out rigid fiber glass and solid polycarbonates sheets plastics are good materials for sound insulation ... the polycarbonates are said to be stronger than glass and is widely used in the building industry. For example linkway shelters, phone booths etc.

yup, its true, using vacuum will work. according to the law of physics, sound can travel through any other medium except vacuum.legin said:
wait egg shells or egg cartons?ahahahahahaha.well i read somewhere that egg cartons dont work.cause they don absorb the sound they jus deflect it.so get something that absorbs something that "kills" the room.the main thing is to dead-end the room as possible.so thick cloths and carpets will do reali great.

but sound travels faster in solid than air.

yea but solid absorbs soundwaves.i mean tink it common sense.you go to a place wit little solids and clap.u hear an echo.u put in a few couches and chairs and u clap.suddenly the clap feels flat.wit no echo bouncing back.so when soundproofing a room the idea is to do that fit in loadsa thick carpets and stuff and kill the sound.mainly for drums cause if the room isn dead and u record it'll sound awful with so much sound bouncing back and forth.so the idea is to not let the sound bounce back and get recorded.yea.
hi dudes, great exchange of ideas in this thread. Xtra creative ideas actually. - from what i have read I think there seems to be a confusion between sound proofing and room treatment here.
legin - you are right. Its easy to control reflections in a room when it is treated with more absorbative materials. In smaller rooms the surfaces are treated much heavier due its small volume - however with smaller rooms you get the problem of trying to control the lower frequencies. These create the muddiness and boominess during recordings. Lower f's are better absorbed with panels (vibration or movement of the panels in response to the sound waves). Carpet, fiberglass, rockwool and other cloth type materials work on the higher frequencies. Thus knowing what material to use and how much of it is a delicate job -as too much or too little of a certain material can change the rooms response dramatically.
In larger rooms treatment is easier as you have more volume to play around with. But the same concepts apply. Treatment is all bout controlling the sound in a room...
On the other hand -(let me take a breather - huh)- even though the material used for the treatment of the room assists in the sound proofing - they mainly work on air-borne sounds and not structure borne sounds such as the impact of drums, police running outside of the corridor 8O and knocking down your neighbours door! :? These kind a sounds are best gotten rid of by building floating rooms ( a room inside of a room).
The best way to sound proof your room is to build a room inside of a room. But this is expensive you'll have to check on the floor loading specifications of your home. The floor loadings cant take the extra weight of the material also i think its against hdb guidlines?.
Theres a good article on MIX magazine http://mixonline.com/online_extras/sound_absorbing_materials/index.html
what kinda music . instruments are you playing in your studio / room and at what volume and whats your budget. This'll help in my advice.
Aaahhhh this dude just went brain-numb

I think the best way to soundproof is to get thick slabs of concrete and make the walls really really thick. Room within a room, yeah.
I think most of the ideas of carpets, egg crates and bass traps are more to do with acoustical treatment rather than soundproofing. Hence the discussion about absorbing and reflecting. I can vouch that egg trays do absolutely nothing in terms of soundproofing, but with some work, I think it can help with deflecting the sound.
From what I understand, most of the fabrics and mattresses and cloth and whatelse helps to absorb the higher frequencies. For lower frequencies, you'll have to use or construct bass traps or something along that line.

I agree with kithsa that the concrete slabs are the best way to sound proof a room. The heavier and denser the material the better it will stop sounds. I've heard that many people use lead to line up their doors and walls to give them density and prevent them from being too thick.
anybody else heard about this?
Dude out!
