Autumn 18 for programme students

Intended learning outcomes

The aim of the course is to teach students basic knowledge of sound and vibration measurements as well as analyses. Students will learn the ability to handle common acoustical measurements and to design new experiments in their future work.

After the course students shall be able to:

  • Perform standard measurements in acoustics and in vibration, understand physics behind the measurements.
  • Design new measurements according to requirement
  • Criticize and find possible problems in measurements

Course main content

The course consists of theoretical and practical parts. In the theoretical part, students will learn basics of measurement techniques and the physics behind, principles of sensors, error analysis and the ways to reduce measurement errors, and the relevant International Standards. On the practical side, students will carry out around six experiments covering the following topics:

  • Basic acoustic measurements, influence of environment
  • Sound power measurements: sound pressure and sound intensity methods
  • Air-borne and structure-borne sound transmission loss
  • Basic vibration measurements, influence of the sensors
  • Sound absorption and surface acoustic impedance
  • Reverberation time and different ways to measure structural loss factor


Basic courses in mathematics, mechanics.
