Sound Insulation
On Ceiling Reduces
Noise in Home
AeousticuI Tile Absorbs
Waves Instead of
Rejecting Them
BY LAWRENCE CROLIUs.

Have you ever noticed how mar
velousiy quiet most modern Offices
and other public rooms are these
daysP Regardless of the hubbub
Of voices, typewriters or dishes,
there seems to be a delightful hush
over everything, and tangled nerves
are at last securing q long-needed
respite. This new era Of noise
lessness is not due to the lowering
of voices, the silencing of type
writers or the rubberizing Of dishes,
as you well know, but is brought
about by the use of clever new
sound insulating materials.
Next time you are in nicely
hushed room somewhere look at the
ceiling and you will no doubt no.
tice that it is made of specially
prepared materials. These materials
are porous, or made porous, so that
wandering sound waves are abb
sorbed instead of being hurled back
at your suffering ears. Cell
ings are the prime offenders, for
some reason or other, and If the
crashes and shouts can be taken
in up there the chances are very
good that you will have q quiet
abode.
There are a number of rooms in
your house or apartment which
could very easily stand bit Of
sound conditioning no doubt. Take
the kitchen for example. You prob
ably have no idea of the additional
strain on your nerves and DISPOSE
ton which is imposed by the clatter
of dishes. Living rooms could be
made far pleasanter places for COM
bined activities, like reading and
bridge playing, if some means were
only provided to soften the uproar
caused by a number of frantic
voices.
Also Heat Insulator.
II you would like to silence a
room or two it can now be done
with a new acoustical tile which
not only acts very efficiently but
looks well to boot. Made in either
q smooth or rough finish, with
factory painted surface in white,
ivory or cream, this material is
filled with a great maze of micro
scopic pores which run all through
each tile. These pores absorb the
sound waves and prevent them from
bouncing back, as we said before.
The standard thickness of these
tiles is / inch, and they are made
in a number of sizes, ranging from
6 by IL inches to IL by "a inches.
They are surprisingly light in weight
and can be installed with a mini
mum of labor by mailing or cement
ing In place.
Because of its thermal efficiency
1t will act as an excellent heat in
sulator, and, furthermore, 1t is nom
combustible. We are also advised
by the makers that its painted sur
face will reflect a large amount of
light and help to illuminate the
room more effectively while 1t is
quoting it down audibly.
