Acoustical engineers are required to demonstrate knowledge of the basic methods for acquisition, analysis, processing and reproduction of audio data and audio material. They must be familiar with the theoretical fundamentals of these techniques and be capable of applying them to practical engineering problems.
The first part of this module covers a range of basic signal processing techniques for the analysis and processing of audio signals. The theory is reviewed of a number of topics that students have encountered in other modules with emphasis on their relevance to audio technologies, and elements of digital signal processing are introduced to students. Students are trained, especially through computing tutorials, to apply these theoretical tools to practical engineering problems.
The second part of the module covers the fundamentals of systems and technologies for audio capturing and reproduction. The concept of channel quality and its objective descriptors (noise, distortion, etc.) are explained and put into relation to human sound perception, some aspects of which are introduced. The principles of operation of stereo and surround sound systems are introduced and demonstrated.
It is emphasized that the theory of some of the topics is covered in this module at a basic level. An advanced theoretical analysis of these topics will be provided during the third- and fourth-year modules.
