Course content

The course builds on basic acoustics courses for applications in room and electroacoustics. It provides a fundament for understanding how sound is perceived in rooms, and to understand the principles for various sound reproduction systems. Through laboratory exercises the students should achieve a practical knowledge of acoustical measurements in room and electroacoustics.

Topics covered include: propagation, radiation, scattering and absorption of sound in room and electro acoustics. Psychoacoustical aspects of listening in rooms. Directional hearing and the foundation for sound recording and sound reproduction, electrical analogy circuits for mechanical and acoustical systems, room acoustics, acoustical measurement techniques, signal processing related to electroacoustic.

Learning outcome

Knowledge:
The candidate has:
- thorough knowledge about theoretical models for sound fields in rooms
- thorough knowledge about sound radiation, reflection, scattering and absorption
- good knowledge about the functionality of various electroacoustic transducers
- thorough knowledge about measurement techniques and related signal processing in electro acoustics.
- good knowledge about various sound recording and reproduction systems

Skills:
The student is able to
- Predict, measure, and analyze sound fields in rooms.
- Analyze and design connected electrical/mechanical/acoustical systems, in particular microphones and loudspeakers.
- Analyze how a sound field in a room will be perceived by a listener.
- Perform and analyse impulse response measurements in room and electro acoustics.

General competence:
The student is able to
- Write clear and concise reports
