All about the course
MSc Audio Acoustics is available in flexible study formats, including full and part-time pathways, delivered on campus or via distance learning. Please be advised however that the course is intensive – we recommend about 38 hours study per week full-time or 19 hours part-time.
This course comprises eight 15 credit taught modules, followed by a 60 credit dissertation project. For full-time students, taught modules take place in trimesters one and two, followed by the project module in trimester three. For part-time students, taught modules are spread over trimesters one and two of two years, followed by the project module in year three.
Note: The ‘Measurement Analysis and Assessment’ module includes a lab week (takes place in the Easter break), which requires mandatory attendance for distance learning students. Depending on your nationality, you may require an ATAS certificate and Short Term Study Visa.
In this module you will develop a systematic understanding of the physical and mathematical representations of vibrating systems and acoustic waves in 1D, 2D and 3D. You will learn about the descriptors and physical units of acoustic and vibration phenomena, and apply critical thinking to understanding of the assumptions and limitations inherent in acoustics and vibration theory. Using this, you will solve advanced problems in acoustics by application of theory and mathematical techniques.
Loudspeakers and Microphones (year two for part time)
In this module you will learn about the fundamental principles underlying electroacoustic transduction as well as investigating the interaction between a source, its acoustic environment and the listener. These effects will be described by mathematical models, which you will study both on paper and numerically by programming them using Matlab. You will also examine the practical application of loudspeaker and microphone systems, and investigate how they are used in arrays e.g. for spatial audio applications.
Digital Signal Processing and Machine Learning (year two for part time)
This module aims to give you an understanding of how acoustic signals may be handled and processed digitally, considering the benefits and limitations. You will study the decomposition of signals in frequency and their manipulation using digital filters, including design and analysis techniques. You will then go on to develop knowledge of advanced signal processing methods based on adaptive filtering and machine learning, including an awareness of their basis and limitations, whilst gaining the skills to apply them.
Room Acoustics (year one for part time)
This module aims to provide you with a thorough grasp of room acoustics principles, including theoretical models for both low and high frequencies, developing your ability to apply these in order to analyse existing rooms or design new ones. You will study wave theory and statistical theory for acoustic enclosures, including objective descriptions of and how these tally with listeners' perceptions. Techniques for designing and applying sound absorbing and scattering treatments will be covered, and you will consider the effectiveness and limitations of these in important application areas such as musical performances spaces and critical listening rooms.
Computer Simulation for Acoustics (year one for part time)
You will learn the fundamental principles of computer simulation techniques: geometric room acoustics, finite element method, and boundary element method using COMSOL and related software packages. You will undertake practical problem solving using computer modelling of acoustical systems and assess the field of application, accuracy and limitations of the computer simulation methods.
Psychoacoustics (year one for part time)
This module is about linking the acoustic signals we measure to peoples’ subjective responses. You will gain an understanding of how the auditory system allows humans to perceive different attributes of the surrounding acoustic environment, and develop a detailed understanding of how low-level percepts such as pitch arise from the physiology of the ear. You will then study how these are linked to high-level attributes such as emotional response, and how this drives good subjective experiment design.
Transducer Design (year two for part time)
In this module you will extend the knowledge you acquired during the Loudspeakers and Microphones module to study their design principles in greater depth. You will analyse the design of electro-dynamic and distributed mode loudspeaker systems, including the interaction of the electrical, mechanical and acoustical properties to determining sensitivity, frequency response and directionality. This will include study of two-port networks methods and the method of analogues. Practical issues such as radiation efficiency and non-pistonic vibration will be considered, and analysis will be extended to vented, transmission line and band-pass systems.
Measurement, Analysis and Assessment (year two for part time)
This module aims to equip you with the necessary knowledge to specify and undertake appropriate acoustic measurements, including understanding their limitations, and being able to analyse the data you produce. You will learn how to effectively undertake standardised acoustic measurements, taking full account of uncertainty introduced throughout the process. You will also gain a comprehensive understanding of the scientific principles underlying these acoustic measurement techniques, thereby helping you to apply them better and know how to adapt them or propose new methods where appropriate.
Audio Acoustics Project
The aim of the project is for you to carry out, under supervision, an extended individual study into a topic in audio acoustics. The topic will be agreed with your supervisor and can be industry based if appropriate. You will be marked on your initiative and project management, as well as your ability to bring together the skills, knowledge and understanding you have acquired from the course. The project module is often used to further develop specialist interests of students, for example audio product design or emerging measurement and/or analysis techniques.
Please note that it may not be possible to deliver the full list of options every year as this will depend on factors such as how many students choose a particular option. Exact modules may also vary in order to keep content current. When accepting your offer of a place to study on this programme, you should be aware that not all optional modules will be running each year. Your tutor will be able to advise you as to the available options on or before the start of the programme. Whilst the University tries to ensure that you are able to undertake your preferred options, it cannot guarantee this.
What will I be doing?
The majority of teaching and learning is delivered through tutorial and seminar groups. All students benefit from the supply of a range of high-quality teaching materials, books and software. Interaction is face-to-face wherever practical, but we also use web-based learning support packages (databases of materials, discussion boards etc.) and there is a strong focus on guided self-learning. Distance learning students can stream classes via our Virtual Learning Environment, either to participate live or watch later.
Assessment is generally in the form of assignments, which help to develop problem-solving and analytical skills. The ‘Measurement, Analysis and Assessment’ module includes practical group work.
- Taught modules are assessed using assignments
- The project is assessed using a dissertation (weighting 80%) and a presentation (weighting 20%)
