Objectives and Content
Objectives:The objective of the course is to give a general understanding of the characterization and use of transducers in acoustics / ultrasound. The course is relevant for basic research as well as for industrial applications.
Content:The course gives a general introduction to characterization and use of transducers in acoustics and ultrasonics, as a basis for basic research within acoustics and ultrasound as well as for technological industrial applications. The course addresses transduction theory, equivalence, quadrupol-, discrete element- and distributed element models, piezoelectric materials, models for piezoelectric transducers, interaction with the sound field, methods for measurement and calibration, electric and acoustic matching, tranducer systems and arrays, construction and applications. The course is a pratical course, which includes exercises and laboratory assignments.
On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
The student can
- use examples on equivalence description in analysis of acoustic transducers
- explain linear theory which is used to describe piezoelectric materials
- independently conduct and analyze laboratory assignments and the measurements that follow
The student can
- describe examples of piezoelectrical resonators and their use in transducer constructions.
- has insight in fundamental principles of acoustic transducers, with emphasis on description of important measurement methods to investigate transducer properties
- can explain the use of acoustic transducers relative to electronics/instrumentation and coupling to the sound field.
The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.
