Description of Teaching and Learning Methods

The module consists of the lectures and exercises. The exercises are mostly done on computers, either in Python (basic computations) or a finite element software (more involved tasks). Each participant is assigned a specific acoustic problem and support is given for performing the numerical computations. In the end a written report is to be submitted and graded.
