New Method of Reception
Eliminates Distortion-Test
Successful

NEW YORK, July 1.-THE sound
box of a monograph and a needle
were media of wireless reception in
laboratories at 90 Fifth avenue in
the first known demonstration of
a receiving set capable of capturing
signals without the use of head
phones or loud speaker.
The needle, following the impress
sions of wax disk, brought to the
box the clear sound of the proceed
irgs at the Democratic convention.
Unlike the photograph method Of
absorbing sound Impressions through
the air, this receiving set was the
first of its kind to record electrical
impulses, it was said.
Say Distortion Is Ended.
The impulses were transmitted
directly from the set through wires
t. a second sound box. To the sec
ond box was attached needle
which, in turn, made first impress
sions on the wax. While the rec
ord was being instilled with sound
properties during the latter process
another needle was started on the
fiji st impressions and the first box
was sending convention speeches,
bell-like in clarity, through a horn.
According to wireless experts who
were present this demonstration
marked a new era in radio recep-
ton. The system, they explained,
is the first of its kind to produce
loud wireless sounds without distor-
ton.
The inventors of the set are J. G.
Byers and Hartwell w. Webb, re-
cCrding engineers of the Advertis-
ing Record Corporation, in whose
laboratories the demonstration took
place. Byers and Hartwell had an
IDEA they could improve the sound
OF an ordinary record by transmit
ting music or words to the record
ing disk by electricity.
May Supplant Loud Speaker.
when we saw that the idea
worked out" Byers explained, "it
occurred to me that the same prin-
ciple could be applied to radio re-
ception. Hitherto the only records
made of wireless signals had been
made through the air in line with
the Edison system of recording
The diaphragms of the instruments
were out of tune with each other,
and the result was distortion"
The inventor said the discovery
night mean the supplanting of the
| loud speaker by the monograph,
| but he said he was not interested
, in this angle of the snvention's pos.
sibilities. He said it's sole value to
HIM was its great practicability in
recording music, entertainment and
public utterances over the radio.
| The wax disks made in this way
ere being used as models for 10000
records a day, he explained.
The Advertising Record Corpora
tons officials plan to use the re-
verse process of Byers' invention in
a commercial plan.
Sees Clearer Broadcasting.
'By so doing" he explained, 1.-The
records could be played into a
microphone en- the same principle.
No sound would be heard in the
radiocasting station. Where the
signals are received miles away
they are heard with the same loud
less and quality that characterized
them when they were originally
sent. There will be no sound of
the monograph.
Our company plans to record
New York entertainers, and then
to play their records in country
localities too far from this city to
receive our concerts
Colonel E. ]. Barrett, commander
Of the Wisconsin department of the
American Legion, is head of the
company. Mr.. Webb is laboratory
chief and secretary and treasurer.
He aided Byers in perfecting the
set.
