PhD Course - Research topics in acoustic technology
DTU Department of Photonics Engineering
To develop the student’s self-learning ability and to increase the knowledge of recent literature within the student’s own research area and related topics. To improve the student’s scientific communication skills and promote scientific discussions of current topics in acoustics.
Learning objectives:
A student who has met the objectives of the course will be able to:
- Present, discuss and critically evaluate current topics in recent journal papers
- Understand and explain the principles underlying modern room acoustic modelling techniques
- Understand and explain fundamentals of acoustic transducer technology
- Understand and explain the principles used in advanced acoustic measurement techniques, e.g., array-based methods
- Understand and explain fundamentals of structure-borne sound
- Understand and explain radiation of sound from vibrating structures
- Understand and explain the psychoacoustic principles used for modelling perception and speech intelligibility in room acoustics
- Understand and explain the psychoacoustic principles used in estimating annoyance in environmental acoustics
Contents:
The course deals with current research in theoretical and experimental acoustics, such as advanced measurement techniques, e.g., beamforming and acoustic holography, analysis and reduction of structural vibrations, determination of room acoustic parameters and their effect on perception, the vibroacoustic properties of buildings, and the behaviour of the loudspeaker for small signals as well as in the non-linear domain. Each student should give two oral presentations over the course of the year. One of the presentations should summarize and discuss the purpose, the methods and the key results in selected recent scientific publications from high-profile journals and should emphasize the impact of the findings for future research directions; the other presentation should focus on the specific research topic of the individual PhD student and closely related areas. In addition, a written summary of the presentations and relevant discussion is required. Each student should to attend at least 70% of the presentations throughout the course. The presentations and the written material will be collected during the course and serve as the basis for evaluation.
