Intended learning outcomes

The overall aim is to promote the development of quiet and vibration-free products and processes. The course participants should be provided knowledge necessary to carry out a relevant analysis of the sound and vibration properties of a product. The knowledge should also serve a basis for possible further studies in the sound and the vibration field.

After completing the course the student should be able to

  1. Account for and explain key sound and vibration concepts and quantities.
  2. Account for environmental consequences of sound and vibration.
  3. Account for, explain and critically choose relevant mathematical models and methods to describe important sound and vibration quantities.
  4. Apply relevant mathematical models and methods to calculate important sound and vibration quantities.
  5. Measure a products sound emission properties.
  6. Measure and assess the hand-arm vibration exposure of a handheld tool.
