'LOUDNESS' PERCEPTION:
McGill Considers Experiment

DAILY OFFICIAL BULLETIN

By ELLEN SILVERMAN
and ARNOLD WEINGARDEN
"From my experiments I feel
that there must be a relation be-
tween time to react to a sound
stimulus and the intensity of the
tone," Prof. William McGill of
Columbia University, said yester-
day.
Prof. McGill spoke at a psychol-
ogy colliquium on the subject of
"Loudness, Latest Model."
"One factor which must be con-
sidered in .such experiments is
that a subject's. loudness function
is repeatable," he said.
Loudness Function
The loudness function is com-.
puted on the basis of verbal re-
sponses to tones on a scale moving
from the loudest tone heard to
the weakest. A subject is ask to
react by indicating which tones
he thinks are the "loudest" in the
series.
In such experiments, results are
shown to be repeatable with a
single subject but vary between
subjects. The reactions of some
subjects can be plotted as linear
expressions, while with others the
graph is a curve.
Since this data resulted from
the experiments, Prof. McGill in-
dicated he had thought that per-
haps other than subjective means
could be used to measure loudness.
One method which he tried was
to calculate the reaction time of

J' 4 '. }::= ~4f :)' l +$^ J. ':i}$ 'h} r }1,"::i "'.'.. N:i+.?.}W.:ln /11. S /r_

PROF. WILLIAM McGILL
... research on sound

subjects in response to tones
heard.
He found that in experiments
the relation between loudness and
time to react became a fairly
stable function. However, it was
then necessary to postulate what
produced the reactionytime.
Mervyn Stone, a psychologist,
analyzed reaction times and lists
three components of them, Prof.
McGill said. He noted that these
three divisions were the time for
the neurological process to take

-U

place, the time required to decide
on an appropriate response, and
finally the time to execute it.
The times for the first and last
steps are fairly constant in the
presence of any stimuli, that is
of any sound regardless-of in-
tensity measured in decibles.
"Although the decision time
could be thought to be a simple
random variable, plotting it
against sound intensity has shown
that it varies in even steps," Prof.
McGill added.
Integration Process
He concludes, therefore, that
there must be some sort of in-
tegration process which allows the
subject to accumulate evidence in
the presence of a stimuli in order
to make a response. Consequently,
it takes more time to accumulate-
evidence in the presense of a weak
stimulus and less time in the
presence of a strong one.
For, when a weak stimulus is
presented to the subject, his sen-
sory apparatus takes time to ac-
cumulate evidence that it is pres-
ent, while with a stronger stimu-
lus the time needed for this pro-
cess is not as great.-
Prof. McGill noted that there is
a definite relationship between the
reaction time and the intensity of
the stimulus. This is due to the
integration mechanism.

A good sword nowadays is hard to find-and in olden times, too.'Many a
feudal lord saw it pointless to joust with a faulty halberd, and for worthy steel
alone the Visigoths sacked Rome.
Today, centuries later, the search for stronger steels goes on. And among those
making most dramatic strides in advancing the state of the metallurgical art
are the research teams at Ford's Scientific Laboratory in Dearborn, Michigan.
In exploring the "world of microstructure," these scientists, using methods of
extremessophistication, have been able to look at iron and steel on a near-
atomic scale. They have discovered secrets of nature leading to new processing
techniques which yield steels of ultra-high strength unknown a decade ago.
The promise of such'techniques seems limitless. As man develops the needs
and means to travel more swiftly on earth and over interplanetary reaches--
wherever economy of weight and space is required-strength of physical
materials will become paramount. This is another example of how Ford is gaining
leadership through scientific research and engineering.
