Course content

The theoretical basis for acoustic calculations with emphasis on analytical calculations. The following will be covered in detail: simple vibrating systems, vibrations of strings, bars and thin plates, the acoustic wave equation, and solutions to this. Reflection, transmission, refraction and radiation of acoustic waves. Sound in enclosed spaces such as rooms and duct systems. Introduction to room and building acoustics. Introduction to the use of numerical methods for calculating acoustic fields.

Learning outcome

Knowledge:
The candidate has
