Topic/Activity: Recent Experiments In Control
Of Early Reflections and Reverberation in Concert Halls
Presented by: David Griesinger
Early reflections and reverberation time are considered to be
the major determinants of concert hall acoustics. Recent work
by David indicates excessive early reflections and reverberation
can obscure the clarity of sound. He has measured and tested remedies
to these problems in several auditoriums locally. Among them are
Jordan Hall at N.E.C, Sanders Theater at Harvard, and Pickering
Hall at the Longy School of Music. He has also been working on
models of inner ear operation and correlating the concert hall
measurement to the models.
About David:
David Griesinger is a physicist who works in the field of sound
and music. He developed one of the first digital reverberation
devices, became a principal scientist at Lexicon, conducted research
into the perception and measurement of the acoustical properties
of concert halls and opera houses, and is the designer of the
LARES reverberation enhancement system. David has investigated
the neurology of the inner ear and created models that emulate
the ears amazing ability to separate musical sources and
speech in noisy environments.
Refreshments will be available at 5:30 PM.
