| Dr Olson determined in the late
1930's and 1940's, then published, that loudspeakers need to
have a back cover on their cabinet so the out-of-phase sound waves
from the
rear of the speaker will not interfere with the sound waves from the
front of the loudspeaker.
Loudspeakers in that era did not have a back-wall!
In the published papers from the same era, he determined that loudspeaker
enclosures should be curved in shape like a household lamp.
The loudspeaker industry followed his
advise regarding closing off a loudspeaker enclosure but for
60+ years ignored his concurrent advice to use curved loudspeaker
enclosures.
Dr Olson originated the scientific
development of loudspeaker enclosures while working at
RCA. Review the links and imagine the history of his innovations
which touches everyone's lives to this day...
He also is one of the inventors of
the Synthesizer and of analog videotape and digital
video disk. His degree is in atomic physics from the
University of Iowa, where another visionary created the
first programmable computer in the early 1930's.
Dr. Olson was Born 1901, Died, 1982.
