Content and learning outcomes

Course contents

The course covers all aspects of classical acoustics with focus on sound propagation in fluids. The fundamental equations of continuum mechanics are first derived, and from this the equations governing classical acoustics are derived. In particular, scattering at interfaces between media with different properties and from solid bodies is discussed. Acoustic waves generated and scattered from vibration bodies with rigid and impedance boundary conditions are covered. Methods for low and high frequency solutions are introduced such as multipole expansion for low frequencies and ray methods for high frequency acoustics. The Kirchhoff- Helmholtz equation is derived and applied to scattering and diffraction problems. The effect of viscous and thermal losses and molecular relaxation processes are addressed.

Intended learning outcomes

Students graduating from the course should:

  • Have knowledge about the division of acoustics as a scientific field and the historical development of acoustics.
  • Be able to derive the classical wave equation and understand underlying assumptions and limitations.
  • Have knowledge about concepts and methods for describing and analysing acoustic fields.
  • Be able to apply multipole-expansion methodology and understand the character and importance of lower order point sources (monopole, dipole, quadrupole).
  • Be able to derive the Kirchhoff-Helmholtz integral and understand its applications.
  • Understand the reciprocity principle and the influence of different types of boundaries in the source region.
  • Have knowledge about different relaxation processes and related non-linear dissipation of sound.
