Course - Acoustic transducers - TSV4165
Acoustic transducers
New from the academic year 2026/2027
Assessments and mandatory activities may be changed until September 20th.
About
About the course
Course content
The course builds on fundamental courses in acoustics and studies acoustic transducers of common types: electrodynamic (e.g. loudspeakers and geophones), electrostatic (e.g. microphones), piezoelectric (e.g. accelerometers and ultrasound transducers), also in MEMS versions, as well as optics-based sensors, such as Distributed Acoustic Sensing (DAS). Via measurements in laboratories and numerical simulations, students will learn to analyze and design transducers systems and predict their performance. The course describes distributed systems, in the form of local fixed array constructions as well as sensor systems distributed over wider areas.
Learning outcome
Knowledge
The candidate is able to:
- Demonstrate thorough understanding of the transduction principles, directivity, frequency response, dynamic range, and linearity of common acoustic transducer types.
- Model and analyze transducers as electro-mechanical dynamic systems.
- Describe basic non-linear and time-varying properties of transducers.
- Understand fundamental methods for determining directions and localizing sources using distributed sensor systems.
Skills
The candidate is able to:
• Measure the relevant properties of some common transducer types
• Predict and analyze the performance of such transducers
• Predict and analyze the performance of distributed transducer systems, either as array constructions or distributed over larger areas.
General competence:
The candidate is able to:
- Collaborate effectively in conducting practical measurements.
- Present and defend results from laboratory tasks in a professional manner.
Learning methods and activities
Lectures, exercises (theoretical and numerical simulations), lab. work and presentation of the lab. work
Further on evaluation
The final grade will be based 75% on the written exam and 25% on the lab work and its presentation.
If there is a re-sit examination in August, the examination form may be changed from written to oral. Retakes can be carried out for written school exams without the lab report having to be taken up again.
If the lab work+presentation has been completed, it can be used for a later written exam for up to two years (4 semesters).
