ISAAC21 Course on Advanced Techniques in Applied and Numerical Acoustics, 23-24 September 2010

About the course

The 2010 K.U.Leuven Course on Applied & Numerical Acoustics will take place in September 2010 in Leuven, Belgium. It is the 21st in a series of courses on experimental and numerical techniques in applied acoustics, organised by the Department of Mechanical Engineering of the Katholieke Universiteit Leuven. This year's edition of the K.U.Leuven Applied Acoustics Course is set up as an extended overview of some recent techniques in applied acoustics with emphasis on applications in automotive and aerospace industry. This overview covers techniques ranging from active noise control to the use of boundary and finite element methods in acoustic problems and is intended to update the expertise of practising engineers and researchers. The overview is application oriented with emphasis on background principles and on practical use of the methods. The course will be illustrated with case studies and real life demonstrations of several experimental and numerical techniques.

Who should attend

The course on Advanced Techniques in Applied and Numerical Acoustics is intended for researchers and engineers, active in the field of noise and vibration analysis and optimization, who wish to update their knowledge on some recent topics in applied acoustics. No previous knowledge of the related topics is required; some general background in the field of experimental and numerical analysis techniques is however advantageous.
