hi, i play the drums for my band and we jam at my church in an office lot very often...
the problem is that the sound there sucks big time..
the floor is carpeted, but the walls are plain concrete, and the ceiling is quite low...
theres a ton of echo and reverb..its ANNOYING!
even the slightest of hits on the drum sounds way too loud,
and the bass guitar is boomy and noisy...
nothing is clear and defined and voices cant be heard above all this noise...

i have been planning on acoustically treating this room to make our sessions sound nicer...

i have read a little about diffusers, bass trappers, and absorbers...but i dont know how to implement this knowledge into DIYing my own panels etc...

can anyone help me? maybe you have a contact who does sound treatment?
or someone who sells the material required?

i would really appreciate anyones help!!

thanks!!

Ethan sometimes posts at Stevehoffman.TV
see this thread there's a discussion about room FR

good luck.

if you malas to DIY can buy stuff from Ethan's company http://www.realtraps.com/ but he said somewhere it's better someone build their own than not have any treatment at all which is why there is an article with instructions

wow..that was fast!...
thanks man...but i was hoping for a link to someone/place that would actually build the stuff or sell the material for me..
have you tried DIYing the stuff on the website before?
was it easy?
thanks!!!

sorry... I updated my post.

no I don't have a dedicated listening room - can't put obvious stuff in the living room HT anyway - so I haven't tried DIY-ing. I would probably print out the instructions and take them to a local carpenter heheh

buying stuff from established companies like realtraps and auralex etc could be quite expensive, which is why you might have seen some studios with egg cartons on the walls...

Isn't soundproofing the same?

It's about absorbing the waves and not letting them bounce/echo/vibrate, etc..

no..soundproofing is not letting the sound escape the room...like so the neighbours dont complain and stuff..it doesnt make the music in the room sound BETTER...

laowai there are a lot of people who believe ... very strongly... that the most important sonic component after speakers, is the room itself.

it makes sense because the sound from speakers interacts with the room before and after reaching your ears - there'll be reflections etc etc.

The confusion is the term used.

You must think soundproof is only for not letting sound go out.... u referring to door only?

But it's actually could mean doing up the whole room so that it's absorbing sounds 'inside' the room, so that it doesn't escape out the room from all 4 walls, ceiling and floor.

If going to sound studio, cinema, etc..... you would notice dead silence inside, which in turns means no loud noise heard from outside or neighbouring hall/studio/room as well.

So, theoretically .... soundproofing = acoustic treatment. Unless of course, you are saying acoustic treatment does more than just absorb .... it enhances?

sound absorb and diffuse is two diff thing. too much absorbent will not make your hifi to sound nice. correct me if wrong

Soundproofing is not acoustic treatment.

He just mentioned in his post, and he is right.

Soundproofing proofs the room from allowing sound to leak.
Acoustic treatment fixes the acoustics of the room.

laowai, in audio these terms are used with those meanings that everyone is in agreement with

soundproofing a room doesn't mean only doors - double screening windows etc that also doesn't let outside noise into the listening room. it doesn't however change the frequency response of a room (perhaps you can follow this discussion thread I linked in my first reply)

for example, your room may produce a peak node at 60Hz that makes the bass sound boomy, even if the freq response form the speaker is flat.

Room treatments like bass traps can cancel this peak node and return the frequency to flat (but it doesn't prevent the sound from leaking out of the room unless you soundproof the room)

I have used a relatively cheap material for my HT room. That material is the Superlon's sheet (the same material that they used for refrigeration or air cond ... those black spongy thing)

I am quite happy with the result for my HT room... in term of sound and also asthetics.

Where did you get the Superlon sheets from? How much is the cost?

I bought them from an air-cond supply shop in Klang. Superlon sheets come in many thickness. I bought the 13 mm thick, 3' x 4' size. Cost approx RM15 per sheet.

hmm...this superlon thing sounds interesting....
i just found this thread again...
anyone wanna add anything?

Hey people!
Do any of you know where to buy this kind of stuff?
or how to get it.
Really appreciate if anyone can help.

where s the shop located. klang is my hometown. can u plz post the pic
