40th Anniversary of
Statistical Energy Analysis

February 6, 2000 marks the 40th anniversary of Statistical Energy Analysis.  On this date in 1960, Richard H. Lyon wrote in his notebook "Energy Flow between Linearly Coupled Modes," and with that note SEA was conceived in its embryonic form.  Analysis and computations on subsequent pages set the framework for SEA as it was to developed in the coming decades.  Now, 40 years later, SEA is a widely used noise analysis tool for coupled structures and for structures coupled to fluid media.  Several commercial SEA numerical analysis software programs are available.  These aid users in the application of this powerful tool to specific design problems. A glimpse of SEA in its nascent form may be seen above.  In honor of this 40th anniversary occasion, Dr. Lyon's book Theory and Application of Statistical Energy Analysis (with Richard G. Dejong), long out of print, has been made available through Amazon.com.
