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 ear’s amazing ability to separate musical sources and speech in noisy environments.

Refreshments will be available at 5:30 PM.
