Date: Sunday, March 18, 2007
Time: 6:00 PM
Place: Boston University, Life Science & Engineering Bldg, 24 Cummington
St, 1st Floor Conference Room, Boston, MA 02215, (617) 271-6588
Featured Guest: Dr. Barry Blesser
Topic: His new book: Spaces Speak, Are You Listening?
Experiencing Aural Architecture (with Linda-Ruth Salter)
We experience spaces not only by seeing but also by
listening. We can navigate a room in the dark, and "hear" the
emptiness of a house without furniture. Our experience of music in a concert
hall depends on whether we sit in the front row or under the balcony. The
unique acoustics of religious spaces acquire symbolic meaning. Social relationships
are strongly influenced by the way that space changes sound. In Spaces Speak,
Are You Listening?, Barry Blesser and Linda-Ruth Salter examine auditory
spatial awareness: experiencing space by attentive listening.
Every environment has an aural architecture. Integrating
contributions from a wide range of disciplines--including architecture,
music, acoustics, evolution, anthropology, cognitive psychology, audio engineering,
and many othersSpaces Speak, Are You Listening? establishes the concepts
and language of aural architecture. These concepts provide an interdisciplinary
guide for anyone interested in gaining a better understanding of how space
enhances our well-being. Aural architecture is
not the exclusive domain of specialists. Accidentally or intentionally,
we all function as aural architects.

Dr. Barry Blesser is considered one of the grandfathers
of the digital audio revolution. He invented and developed the first commercial
digital reverberation system, the EMT-250 in 1976, helped start Lexicon
in 1971, published the landmark paper, "Digital Processing of Audio
Signals" in 1978, co-chaired the 1st International Conference on Digital
Audio in 1980, and was an adviser to the US Justice Department on the Watergate
Tapes in 1974. Dr. Blesser was President of the Audio Engineering Society
in 1980.
Dr. Blesser's first love for electronics began when
he was 2 years old sitting in the kitchen observing the bright blue arc
of a power transformer going south. From that point on he was fascinated
with the "power" of electricity. As a teenager, he was considered
a genius by his family because he could fix radios by replacing vacuum tubes
by observing which ones had dead filaments.
Dr. Blesser's career in audio was launched at the age
of 20 with the fantasy of building a portable concert hall. Although he
had no idea how to do that project or even if the project was doable, the
passion continued to burn for the next half century. Never underestimate
the compelling influence of a dream. In fact, the book is just an extension
of that early vision. The book was a family project with the fusing of the
two cultures taking place at the family dinner table with his wife and co-author,
Dr. Salter. "Everything in the book had to make sense to a social and
physical scientist: We kept setting the bar higher and higher, and if I
had not called a stop to those great discussion, the book would have remained
a manuscript for another two decades."
There will be refreshments outside the room at 5:30.
