Course specific prerequisites

Basic course in acoustics (e.g. Introduction to audio technology and acoustics)


The course intends to give an in-depth knowledge about structure- borne sound and its control. The course focuses on the prediction and control of sound propagation in structures and the radiation of sound from structures. The course is recommended for those students who intend to focus on noise control engineering. It is highly advised that students continue with Technical acoustics 2, where the subjects of Technical acoustics 1 are practiced on a real-life example.

Learning outcomes (after completion of the course the student should be able to)

  • describe and apply the fundamental concepts used in the field of structural acoustics (wave approach, modal approach, description of damping, etc.),
  • apply the equations that describes wave motion in fluids and solids in order to describe wave propagation and reflection/transmission at interfaces between different materials and geometries (e.g. blocking masses, elastic interlayers, junctions)
  • describe and evaluate the functioning of numerical tools such as SEA in the field of structural acoustics
  • apply SEA for simple cases
  • understand and discuss different damping models applied in structural acoustics
  • explain the coupling between wave in fluids and solids, along with be able to apply this theory to predict sound radiation from structures in a qualitative and quantitative way,
  • use damping treatments such as simple damping layers and sandwich design for noise control problems


  • Discrete (lumped) dynamic systems.
  • The vibration field and wave types in solids, beams and plates.
  • Vibrating finite systems.
  • Mobility description
  • Modal description of vibrational fields. 
  • Influence of impedance variation, blocking mass, elastic interlayer
  • Damping mechanisms - damping models - damping layers
  • Statistical Energy Analysis
  • Basic radiators, radiation from vibrating surfaces.
  • Integral equations, BE-calculations. Radiation factors.
