VISIBLE REPRODUCTION OP THE HUMAN VOICE.—
Pd. Leos Scott, a corrector of the pram, ha fantod an in-
genious method fir obtaining the vibrations of the human
voice exprewd in some, wntten, SO to Say, tri the SOWS
itself. If we examine the human ear, we fin it thiedy
composed of a tubs ending in the tympanum, an inclined
vibrating membrane. It is well known that sound is trans-
mitted with extraordinary purity and rapidity through tubu-
lar conduits, and it would appear that, if these were no dis-
turbing causes, the transmission might be continuers to an
indefinite distance without any diminution of intensity.
There is an experiment on record, tried about Eby years
ego by M. Blot, who, placing himself at one of the ex-
tremities of a tubular aqueduct 950 metres in length, car-
ried on a conversation in • low voice with another person
situated at the opposite extremity. These facts have been
nosed to account by M. Boott in the following manner
• tabular conduit receives the a-Priam= of the human
voles at one of its extremities, shaped like • fennel; at
the other extremity there is • vibrating membrane, to which
• very light pencil or atylua is attached. This stylus mite
upon • slip of paper. covered with a coating of lampbtam,
and Is made by the aid of clockwork to unroll from • cykindar
while the person whose voice Is to be experimented upon Is
M. The stylus, In receiving the vibrations
eg voice through the tube, marks the paper
with undulating lines the different inflexions.
Thera times are afterwards indeh fixed by taking photo-
graphic impressions of them. A somewhat similar praises
had been employed some time ago by M. Werthheim. to
obtain the graphic rapressatation of the vibrations of a
tuning-fork; but M. !kora Is the first who has attempted
anything of the kind with the human voice. The coutriv enoe,
though still in its infancy, ha already led to a curious result,
via., that the clearer and purer • sound is. the mere regular is
the curve described by the stylus ; yells and other discordant
sounds producing Iranian and therefore not isociwonotis
undulations, while tremulous and indistinct sounds owes
small secondary undulations connected with the principal
one.—Gaispurni.
