Wooden Ceiling Diffuser

[JackD201]

Jack- does Almute make any 'off the shelf' panels, or is it all custom work?

Hi Bill,

Over here you have a choice of ordering them prebuilt in Japan where they have existing templates or just ordering the materials and adhesive. They gave me the plans for the wave for free. My wave cost me a shade below a thousand dollars thanks to our cheaper labor. If I had ordered the admittedly prettier Japan built one I was quoted $4,800. Yikes!

I'll try to get pics if ceiling work done for my friend that was much simpler. The panels were't bent just slanted the way rives does their thing. Each panel is 2'x4'. One would need only 6 to 8 panels for a room of normal size. Bare panels are as close to off the shelf as it gets. Very close to pressed fiberglass that is most commonly used except it isn't itchy. If one wants more absorption they can be easily backed by fiberglass, put in a box with rockwool or anything else that's usually done. If less, backed with perforated gypsum or closed off with thin ply.

Absorption Coefficients can be found at www.wsdg.com just download the absorption coefficient .xls in the resource page. The different types are under "Peer Almute".

Thank you. I like the aesthetic of the 'wave.'

Beautiful room Jack, I dont hate you!

I think if you are doing the room yourself you should evaluate every addition to it by ear!
This way you will be able to tune it to your liking and your system...
I just fixed my listening room (14 X 21 X 9). I took everything out of the room!
Left the speakers bare in the front and my listening chair:
I brought back every item of furniture or treatment and had a listen to a couple of test tracks after each item.
Somethings did kill all sound in a terrible way and were dismissed.
I had some blinds I checked up as disfussers but turned out to be the most absobtive material in the room! (got rid of them)
I had an Upright piano that made the biggest difference in the room once it was moved out! Sound needs space to develop!
After a while you get the hang of it and can even start predicting what type of changes adding a certain material will bring.
Most importantly, be sure you can take out whatever you put in if you dont like it....

 

[JackD201]

Yup, everything (and everyone) counts!!!

-- ...Even you Jack. ...Your own physical body is a sound absorber.

Not to change the subject but rather a different way to tackle the same problem is what I am doing in the ceiling of my new room. I am using a specific product that looks like sheet rock but is very absorptive and thicker than sheet rock (5/8" vs 1/2") called sound board. This will be glued and screwed to the underlying sheet rock on all walls and ceiling. Then I will be using a Helmholtz resonator in my ceiling

The carpenter that came to my house last week to take measurements and verify the location and spacing of the ceiling joists just informed me that he is backing out of the project.

wtf??

 

[mep]

That's what I thought Bruce. He had several excuses, but they were just excuses. I think that he felt the project was more of a PITA than what it was worth to him monetarily.

---- What kind of reason did he give you Mark?

EDIT: While I was typing my post real slowly, you posted yours above. :b
-> Work with a new guy, together.

I thought in this economy carpenters and general contractors would be hungry!

Most probably he looked at the KSA250 and though that you would ask him to move it frequently to carry listening tests to check the project evolution!

Funny you mentioned that. I told him that "we" would have to move the KSA-250 out of the way during the installation.

Elementary, my dear Watson.

I have some wonderful contractor stories- they would make for a decent comedy- I could start with the general contractor who, in the midst of our kitchen redo-- a six month project which effectively had us camping out in the living room with a microwave and a bar frig- the guy disappears and goes into rehab. Or the guy who as part of a workcrew, had the bright idea to steal a set of checkbooks from the office- only to use them to pay his own bills. He didn't show up for work one day because he was handcuffed to the wall in the local police station. I've got a milllion of them. Find another contractor. One of the best carpenters I used could always be found at an Irish bar in town. When he was sober, his work was brilliant. Gotta love these guys- in spite of themselves, they somehow make a living.
There are some good ones, though. And if you find one, hang on to him/her.

I used to have a great finish carpenter, but he moved to Vermont. I totally trusted this guy to the point of giving him a key to my house.

The Finns are known for their workworking skills. Maybe he gets the same amount of daylight in Vermont as he did at home?
