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.
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
- Loudspeaker arrays and microphone arrays
The course also comprises one lab exercise.
