"DEADROOM"--National Bureau of Standards researcher adjusts
a microphone in the new NBS echo-free chamber. The walls,
floor and ceiling are faced with - wedges of matted glass fibers.
which absorb over 99 per cent of incident sound.

U

measurement, and investigation
of characteristics of s o u n d
sources.n
Reverberation Chamber
Dr. Cook pointed to the fact
that the Bureau was not -alone in
this type of research and con-
struction.
The bureau also operates a re-
verberation chamber, the sound
properties of which are just, op-
posite to those of the deadroom.
In this chamber, some loud sounds
of, certain frequencies have rever-
berated for 14 seconds.
Panels Rotated
This room is faced with con-
crete, and includes a large tilted
panel in the center. The panel
rotates, and has two loudspeakers
mounted on. either side of the axis.
During the tests, which are re-
motely controlled (the presence
of even one person in the room
introduces extraneous sounds),
the panels are rotated to scatter
the sound.
Another possible use for the
room is the testing of commer-
cial-brands of soundproofing ma-
terial. By placing a specimen of

the material to be tested into the
room and introducing a sound,.
the amount of sound absorption
may be measured -by the strength
of- the echoes in the room.

ALTHOUGH CHRISTMAS VACATION was a joyful event, the

Pagnol's "Topaze," a theatre "must," expires this Sunday. At this
writing only three performances remain and all who enjoy a fast-
paced, brilliantly directed and tremendously funny production. are
urged to attend.
In the past, DAC's talents have shone particularly bright in
comedies and "Topaze" approaches their zenith. The cast, headed

comedy formula, and concerns
an astonishing truthful and
naive schoolteacher at a boy's
school suddenly transported into
the coirupt mileau of French
