Arty absorption panels

(1/6) > >>

alanB:
Some of you may have followed the threads below regarding room treatment and absorption panels in particular.  I saw one of the other members make his own panel a while ago on which his wife painted something interesting.  I built my own a while ago motivated by his example and was quite happy with the results, visually and audibly.

I recently finished a website for my own images (I hesitate to call it art). I take a lot of photo's and wanted a platform for selling/presenting them as a hobby/sideline - as much to motivate me to continue taking good photo's as anything else.  Having said that my images are not photo's, and probably not everyone's cup of tea, I'm not sure what to call them....

ANYWAAAAY....

To get to the point, I added a page to my website featuring the inclusion of sound damping material to a normal canvas frame as a standard option for all my images, seeing as I was building the site anyway. 

I was wandering what you guys might think of the concept, particularly the effect of relatively non-permeable canvas as a covering fabric.  I would appreciate comments from anyone interested.  http://www.abolton.co.za/?q=con,6,Acoustic%20Frames

I like the concept. The only thing I'm concerned with is the "non-permeable" fabric which will lead to less friction (and hence less absorption). What type of absorption material are you going to use, density and overall thickness ?

I think it's a great idea and it would cater for a definite need in the market. The images are of course a question of taste and of them being in harmony with the rest of your interior. The option to provide  / specify images according to individual tastes is just great. Just so that the wife cannot raise objections....

64kg/cubic meter rigid fibre glass 50mm thick held 50mm away from the wall (all this info is on the site).  The canvas acts as a moveable membrane in front of the fibreglass (it is held away from the fibreglass so it can vibrate freely).  My thinking was that sound waves would make the canvas vibrate and thus transfer most of the energy into the damping material which would absorb it.  Only those frequencies that were unable to cause the canvas to vibrate (ie the higher frequencies) would be reflected so in theory I dont see the non permeable canvas having to large a negative effect on lower frequency absorption which is typically the main issue, but would appreciate the comments of those that know what they are talking about.
