| Recommended semester: 7th - 9th semester |
| Scope and form: Lectures, project work (MATLAB simulations) and 3 compulsory laboratory exercises. |
| Evaluation: Oral exam and approval of reports
|
| Examination: 13-scale |
| Previous course: 51222 |
| Prerequisites: 31200 (51001) Fundamentals of acoustics and noise control |
| No credit points with: 51222 |
| Aim: To give the student an understanding of the most important methods of making predictions of sound fields, and to enable the student to choose the most suitable method. To introduce advanced acoustic measurement techniques. |
| Contents: Plane waves and higher-order modes in ducts. Four-pole description of silencers in ducts. Design of acoustic horns. The modal theory of room acoustics; statistical room acoutics. Sound power determination. Measurement of sound intensity. Active noise control. Numerical acoustics (finite element and boundary element methods). Radiation of sound. Spherical harmonics. Sound propagation over a plane surface with a finite impedance. |
| Remarks: The course is a natural introduction to master thesis work. |
