overview SEA Course Description

Statistical Energy Analysis Course
offered by Cambridge Collaborative  

 Purpose

Our seminar is designed for engineers, scientists and research managers who desire training in the theory and applications of Statistical Energy Analysis (SEA). The emphasis of the seminar is on the practical application of the principles of SEA to noise and vibration problems.  Examples of SEA applications are interspersed with theory and modeling procedures throughout the course.  The seminar is concluded with a modeling workshop and software demonstration.
