This so-called Silent Gramophone is the ordinary turntable unit
modified for me in these following particulars: the pickup is electrically
controlled on an a.c. current; there are no tubes of any kind; the
ear-pieces are those used in telephones; instead of an amplification
of sound there is diminished volume; there is a device to control
the volume; it is geared for both short and long records; it will
plug into a lamp or wall outlet with any length of cable, and can
be located any distance from the recipient; the ear-phones may be
applied to the head or laid under a pillow; there is a separate receiver
Compared with the radio this instrument will furnish any selected
music at any selected time. Compared with the ordinary phonograph
this one limits the sound to the person, or several, directly connected
with it by the ear-phones.

I am thinking that you will find some value in the Silent Phonograph.
The time allotted me entirely by the courtesy of Dr.McMechan, for
which I am grateful, as every interposter must be, permits me to add
only that I am at your service at the close of the session to answer
P.S. There were many questions asked and much understanding appreciation
expressed by my fellow anesthetists.
