A Little Bit of History: A Series of Symposia on
"Mechanics of Hearing", by Egbert de Boer

In the period from 1970 to 1980 many new facts about hearing
came to light. To mention a few: in 1971 it became known that mechanical tuning
of the basilar membrane is sharp and nonlinear, in 1974 inner hair cell
potentials were shown to have sharp tuning, from 1978 on otoacoustic emissions
became known as a (possibly essential) by-product of cochlear action (also
demonstrating nonlinearity), and in view of the sharp tuning it became
increasingly difficult to explain cochlear mechanics by a simple model. In 1980
the concept of an "active" cochlea was launched which gave birth to
several theoretical developments. Furthermore, interesting aspects of
spontaneous otoacoustic emissions became known. In short, the time was ripe for
an international gathering of scientists to discuss the new findings and the new
theories. In 1983 a symposium entitled "Mechanics of Hearing" was
organized by Egbert de Boer and Max Viergever; it took place in the picturesque
city of Delft in The Netherlands. The symposium encompassed sections dealing
with the above-mentioned topics, and a few more that can be considered as
forerunners of topics that later scientists concentrated on such as 'phase
transitions and critical phenomena' and 'the Van der Pol oscillator as an
element in cochlear mechanics'. The aim of the symposium was described as:
"The emphasis is on those aspects of the external ear, the middle ear and
the cochlea which, to the best of our knowledge, can be treated by a mechanistic
analysis". It should be noted that this symposium had a motto, taken from
"The Tempest" by Shakespeare:
PROSPERO: - Dost thou hear?
MIRANDA: - Your tale, Sir, would cure deafness.
The motto was meant to remind readers of the book that a good
deal of our efforts in understanding hearing are directed toward helping people
with hearing loss.

The first symposium was highly successful. It has been followed
by a series of symposia with approximately the same fundamental aims. The second
symposium (1986) was organized by Jont Allen, Joe Hall, Allyn Hubbard, Steve
Neely and Arnold Tubis, it was entitled "Peripheral Auditory
Mechanisms" and took place in Boston, MA. The next few symposia alternately
took place in the USA and in Europe. The third symposium (1989) was organized by
Pat Wilson and Dave Kemp, and was entitled "Cochlear Mechanisms, Structure,
Function and Models"; it took place in Keele, UK. Note here the
concentration of subjects to just the cochlea. The fourth symposium (1990),
entitled "The Mechanics and Biophysics of Hearing" was organized by
Peter Dallos, Dan Geisler, John Matthews, Mario Ruggero and Charles Steele. The
importance of biophysical aspects in hearing theory is evident from the title;
this role is still increasing. That meeting took place in Madison, WI, and the
participants remember the strolls along the lake where many important
interactions took place. The fifth symposium took place in The Netherlands, in
1993. Its site was on a lake again, in Paterswolde, Groningen. Officially this
was the year of retirement for the author of this 'history'.
The sixth symposium took place in Berkeley, CA and was organized
by Ted Lewis, Glennis Long, Richard Lyon, Peter Narins, Charles Steele and Eva
Hecht-Poinar. In this symposium, entitled "Diversity in Auditory
Mechanics", another aspect was brought to the fore, namely, the enormous
diversity of hearing mechanisms throughout the animal kingdom. A real source of
inspiration! The seventh symposium did not take place in Europe but in Japan, a
country demonstrating an ever-increasing occupation with hearing science. The
organizers were Hiroshi Wada and his collaborators T. Takasaka, K. Ikeda, Y.
Susuki and T. Koike. The year was 2000 and the location Sendai, Japan. The
symposium was entitled "Recent Developments in Auditory Mechanics".
The eighth
symposium took place in Europe again, in 2002 on the beautiful lakeside in
Titisee in the Schwarzwald, Germany. Again a magnificent environment and a quiet
setting. The title was: "Biophysics of the Cochlea from Molecules to
Models" showing again the concentration on the mammalian cochlea and the
extension toward molecular biology and biochemistry. The organizers were Tony
Gummer and his local 'crew' of collaborators E. Dalhoff, M. Novotny, M.P.
Scherer and A. Seeger.
The ninth meeting was called "Auditory Mechanics",
the shortest title in the series. The organizers were Fred Nuttall, Tianying Ren,
Karl Grosh, Richard Walker, Peter Gillespie and Egbert de Boer. The meeting was
held in Portland, Oregon, USA, a city providing an inspiring intellectual
environment and located in a state of infinite beauty.
It is stressed that there is no learned society, no
international scientific committee, no institute or funding body that has
continually supported this series of symposia. In all cases individual support
has been sought (and found) from societies, associations and industries.
Although the titles of the symposia do not mention it, the work reported in the
proceedings books constitutes the sole and indispensable basis for the study,
prevention and cure of hearing defects, and all efforts to improve the life of
people who are hard-of-hearing.
