Intended learning outcomes

The course aims at providing the students knowledge about sound and acoustics.
After the course the student should be able to:

  • Recognize, describe and solve simple problems of sound generation, propagation and other phenomena related to sound waves.
  • Know and explain about the human perception of sound.
  • Understand and explain the description of sound in the frequency domain
  • Describe the function and properties of electronic circuits related to audio technology, and know how common audio related measurements are performed.
  • Understand the basic concepts of room acoustic and explain how to influence the acoustics of a room.
  • Know the basics of different audio formats, audio recording and post treatment as well as digital audio and signal processing.

Course content

Basic description of sound waves and physical phenomena related to them. Sound propagation and room acoustics. Psycho-acoustics: the human perception of sound.
