Lawrence Examines
Processes of Hearing

"The process of hearing can be
viewed as a mechanical system in
which the human being takes a
symbol and does something with
it," Prof. Merle Lawrence, direc-
tor of the Kresge Hearing Re-
search Institute, said Monday.
Prof. Lawrence's topic, "Hear-
ing Research Problems and the
Engineer," was one of a number
of speeches held by the engineer-
ing school to explain various scien-
tific fields.
"We have to discover how the
ear is structured, in spite of diffi-
culties in analyzing this part of
the human body," Prof. Lawrence
noted.
Different Technique
Unlike the standard anatomy
text, Prof. Lawrence divided the
ear into functions of the various
parts. "Hearing can be viewed as
three processes," he said.
First, the sound must be picked
up and relayed to the part of the
auditory organs where it can be
handled. Body fluids direct this

portion of the hearing process as
sound waves in the air must be
converted to sound waves in fluid,a
he noted.;
"This is a mechanical operation
carried out by a hydraulic system
which transmits impulses from the;
air to the liquid medium," Prof.
Lawrence continued.
Electrochemical Process
The vibrations in the liquid
then are converted by an electro-
chemical process into impulses in
the nervous system where they
cause sensory cells . to give off a
measurable AC current. .
"Finally nerve impulses are car-1
ried to the cortex," Prof. Law-
rence explained.
Prof. Lawrence used a diagram1
of the ear drum as an engineer-
ing structure to illustrate mechan-
ical aspects of the ear.
"The principles of mechanics
can be used as an aid by surgeons
in performing operations to cor-
rect deafness caused by a mal-
functioning of the ear apparatus,"
Prof. Lawrence noted.
An attempt was made to con-
struct a telpehone based on the
middle ear's components. It was
composed of a stopper from a beer
barrel and the skn of a German
sausage, Prof. Lawrence pointed
out.
But the attempt based on or-
ganic principles was unsuccessful,
while Alexander Graham Bell's
model based on non-organic prin-+
cples succeeded, he concluded.,
Verify Heart,
Ulcer Ills Link
Diets prescribed for u 1 c e r
patients may contribute to heart
disease, Prof. Richard Remington
of the Public Health School found
recently.
A sample-of 1300 ulcer patients,
mostly middle-class Jewish men,
showed a 50 per cent higher death
rate from heart disease than that
found in the population as a
whole.

The University personnel office
annually employs approximately
26,000 workers in clerical jobs Jo-
seph C. Augustine, supervisor of
scientific and technical placement,
said yesterday.
The clerical area is a fairly
stable one. The yearly turnover is
roughly 26 per cent which is about
normal for the average turnover
in industrial clerical work. The
26,000 figure covers all clerical
workers at the University includ-
ing workers at Willow Run, North
Campus, and all other University
buildings, Augustine noted.
Because the University is unable
to hire all its workers from Ann
Arbor and the surrounding area,
the personnel office has set up a
recruiting program to help the
University find qualified workers.
Recruiting Schedule
"A recruiting schedule is set up
which enables the University to
send information on University
employment to various h i g h
schools, junior colleges and col-
leges in the Upper Peninsula and
Give German
Essay Prizes
Alvin E. Fritz, '63, and George
R. Zmudka, '63, won first and sec-
ond prizes in the Edgar Schwai-
bold Essay Competition for their
English and German essays.
Jan Elaine Brundige, '65; Den-
nis K. Kenaga, '65, and William N.
Layher, '65, won first, second and
third prizes in the Kothe-Hildner
contest for German comprehen-
sion and writing.
then to administer tests on the
bisis of this .material," Augustine
said.
The exami Cations test general
knowledge in secretarial work,
spelling and reading comprehen-
sion. The school faculty selects
those students who have done well
on the tests to be interviewed by
visiting University recruitment
personnel later in the school year.
Augustine said this kind of a
program was relatively unique
among universities and enabled
the University to hire people with
above average capabilities for the
work they would assume.
The University has built up a
relationship with the schools and
colleges where its recruitment
program has been effective and
through this relationship it is
given the opportunity to employ
those with "growth potential" and
those who are "career oriented,"
he said.
In addition to the recruiting
done for workers in clerical jobs,
the University also has a program
to encourage potential research
workers to apply for jobs here.

The total cost of the research
program at the University is over
$35 million and because of the size
of the program the University
hires approximately 900 research
technicians, assistants and labor-
atory workers. "The type of work
people under this heading are in-
volved in ranges from washing
laboratory instruments to a re-
search assistant holding a degree
in chemistry or engineering,"
Augustine added.
Augustine pointed to the nation-
al shortage of research workers
seeking research jobs in a non-
academic capacity as an indicator
of the difficulties the University
may have finding qualified per-
sonnel in the future. He indicated
that he saw no particular prob-
lems ahead, due to the University's
reputation in research and its re-
cruitment program.
He said there may be a little ad-
justment to be made in hiring
clerical workers this year as a re-
sult of the new schedule.
