The purpose of this course is to give the students some insight into the challenging and expanding field of Audio. Of primary interest are the properties of electroacoustical transducers. Examples of such are microphones based on different conversion principles with various directional characteristics. Another important example is the electrodynamic driver and we will study how the low and high frequency responses are affected by the enclosure design. We will introduce analogies, as one important tool in the design of transducers. With rooms intended for critical listening - such as control rooms - the acoustical properties are of outmost importance and some guidelines will be presented. The course wraps up with a treatment of the components of typical audio systems such as A/D and D/A conversion, audio effects, and perceptual audio coding.


The course discusses the following topics:

  • Basics of electrical circuits
  • Mechanical and acoustical analogies
  • Acoustic radiation
  • Electrodynamic drivers
  • Enclosure design for loudspeakers
  • Microphones (electrodynamic and condenser type)
  • Sound reproduction
  • Small rooms for critical listening
  • Digital Audio
  • Music recording and production

The course also features lab exercises.
