Good morning gentlemen,
Eddy,that's some nice exposures. Thanks for showing the guys
some of your pics. The ceiling treatments was based around the
fact that elderly listeners especially above 50 years of age do
suffer from distrubances in their hearing due to reverberation
time being longer in an enclosed space, ie. a room and complicated
by flutters & echoes to make enjoyment of music very, very difficult!
Having no choice but to surf the net for information and I found a
couple of websites some enterprising hifi enthusiasts have found
a way around this problem, and came out with products to sell
that users could put up onto the ceilings. Apparently, ceiling
treatment is the only way to counter the problem of reverberation
time for elderly listeners. The treatments on the side walls, and
also the front & back was purely for hifi sonics corrections and
improvements to room acoustics. Hence, visitors would still find
some sonic problems not address yet because of the lack of
treatment to the vertical 4 walls, but the major hearing problem
I encountered was taken care of. Actually younger listeners
would not need this ceiling treatments, just the treatments for
correction & improvement to room acoustics will do fine, as the
younger brains are able to 'filter out' any unwanted sound such
as wrong reverberation time, flutters & very slight echoes.
Built, when Alephman visited last sunday, 3 active subwoofers
was in used. Will be installing a 4th slightly behind on right side
to complete the room pressurisation to about 75 percent optimum.
By the way, since I was into ceiling treatments, I decided to
incorporate air pockets between the ceiling and the layer of
treatments to act as 'buffer' to equalised air pressure caused
by the subwoofers to reduce bass boom. Thre are about 28 air
pockets on the ceiling hence the use of bass traps was not
necessary, at least for the time being. Adding a 4th sub might
require the bass traps, that is yet to be determine.
