Sounds like you really want the hard tile and are looking for justification
???

Perhaps the real answer is that no kind of suspended ceiling is going to
give
you the results you desire. In other words, is the suspended ceiling
concept
likely to give you an echo chamber similar to guitars, etc.?

Let's face it, sound waves are carried by air, and if your ceiling allows
air flow,
then the sound will go along with it.

Let me simplify this issue. If the average Joe goes to the hardware
store
and wants to buy a ceiling tile to reduce the sound coming from the floor
above, which tile should he choose. Without getting to complicated,
which should he choose? People are faced with this choose every
day, surely these is simple answer to this question. Surely the
average
guy does not have time to do in-depth research to find out which of the
two is the preferred choice for sound proofing.

It's a question that I posted on many news groups, but no one
is willing to answer my actual question. It is a simple question.
There
are two different ceiling tiles to choose from. One is light, flexible
and made fiber glass insulation. The other choice is a heavy tile,
that
is
hard (made out of asbestos or dry wall type of material, not sure
though).
Which is better for sound insulation? Simple question right!!

I have asked a slew hard ware store to ask this very question and every
one a ask says the exact opposite. I have always heard that you need
mass and air space to have good sound insulation. My thinking is that
yes, hard objects carry sound, but since this ceiling is free floating
and
supported only by wire, the sound will not travel through the hard tile.
Those that make sense.


PREVIOUS POST:
I was just wondering if I replace my flexible 48" x 24" ceiling tiles
with
the hard type (much heavier) will I notice the difference in sound
proofing?

I call all kinds of hardware stores to see which of the two is better
for
sound. The opinions are split 50/50 between flexible and hard type.
I
personally think the hard type are better, I wonder if replacing them
with
this type will actually make a noticeable difference to be worth
replacing
them?
