General Information

Elective for: BME4-bf, E4, F4, N4
Language of instruction: The course will be given in English


The aim of the course is to provide fundamental knowledge about mathematical and physical methods that are routinely applied in research and industry to model acoustics, i.e., linear wave or vibrational, phenomena. Knowledge on several topics in basic mechanics, linear wave propagation, and discrete oscillating systems will be provided. The course aims at providing the capability to devise simple models of those vibrational phenomena and describe them in a mathematical language, which allows the students to derive simple solutions either numerically or analytically. The knowledge forms a thorough foundation of the physics that is applied in different applications of acoustics. This course also has the purpose to prepare the students for diploma work or Ph.D. research in the relevant fields.
