What are your thoughts on this Jeffrey? I'd imagine that putting enough of those on your walls, ceilings that there would be some attenuation of reverberances and resonances. The approach taken by the author in your reference does seem to be a bit haphazard and who knows if he still even uses it. From a personal, aesthetic, point of view I'd find the sight of a room littered with dots to be somewhat offensive. A pity that he did not take a photograph or two of his room to show us. It would seem that the overall surface area is rather small and that greater benefit could be obtained with something more substantial in surface area. Putting, as he suggested, three disks in the corner seems to not provide sufficient coverage to have a substantial effect. Another thought to keep in mind is that these adhesives tend to be somewhat tenacious and will over time penetrate to some extent into your walls. The same holds true for wall paper in which case their removal will result in a rather nasty looking blotch. Eventually, in the case of wallboard, you will find the need or desire to repaint. The areas where these disks are will have had adhesive leach into them. This may likely require sanding and probably either a light skim coat of joint compound and/or treatment with primer.
Oh, and while I'm not big on typos and have had more than my share of mine while posting, I do find the typos in the link you provided to be most unprofessional and irritating. After all, these sites are meant to convey some degree of attention to detail. How's about you sharing some of your thoughts on this Mr. Chin?
I agree with you. Being that this is a rather inexpensive tweak, the only way to tell is to actually try it. It is indeed aesthetically unappealing. The sonics in my room are good as is w/o any acoustic treatments (just 5 layers of sheetrock and blinds). Frankly, I do not wish to be the guinea pig =) Any takers?
BTW, I use the same felt disks for under my furniture on my hardwood floors
These remind me of the Marigo Audio Labs "Tuning dots" and Golden Sound's(the DH Cones makers) Acoustic discs.
While I may try Marigo's Window tuning dots if I had large pane windows in my HT, I would pass entirely on the tuning dots, felt discs, etc. I opted to scar my corners with DIY corner tunes. Work for me. And cheap.
I'd imagine they do as to whether that's a benefit or not is undoubtably a user preference. I can just imagine the high end manufacturer's shuddering...they must feel like michelangelo did when the pope said, I think that angel looks better over there!
Five layers of sheetrock Jeff? Ceilings too? Was this done with airspaces or some sort of deadening material in between?
my ceilings are exposed brick
the STC class for my condo is rated at 55..purty good.
only bad thing is that you can hear the music through my main door if i really crank it..and of course the bass thru the wall
