Course purpose

The purpose of this course is to give the students 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 design of the loudspeaker enclosure.

We will introduce acoustical, mechanical, and electronic analogies, which constitute a powerful tool for linking the different domains. We’ll also look into stereo and surround sound reproduction and the psychoacoustics related to it. The course wraps up with an introduction to loudspeaker and microphone arrays.

Examination form

Remember that it is mandatory to register for the exam!

A typical exam consists of 1–2 essay tasks and 4–5 problems (5–6 in total). Correct answers/solutions are awarded 5 points. The following aids are allowed at the test: Mathematical tables, electronic calculators without text memory and our list of equations for the course (without self-written notes). A minimum of 12 points is required for a passing grade, as well as approved lab work.
