Updated: about 8 hours ago

General course objectives:

To bring the student in contact with current research and development challenges faced by a partner from the audio and hearing aid industry; to get insight into specific issues in microacoustics; to understand, analyze, and solve a well-defined acoustic engineering problem within a short deadline.

Learning objectives:

A student who has met the objectives of the course will be able to:

  • Analyze a technical challenge in terms of core functionality and target performance.
  • Set up a suitable model using equivalent circuit method, BEM, or FEM to describe a complex acoustic-mechanical problem.
  • Combine models to describe electrical, mechanical, and acoustic components.
  • Consider challenges specific to the microacoustic domain and include them in models.
  • Optimize model parameters to achieve target performance.
  • Analyze simulation results to conclude and design different solutions.
  • Fabricate and experimentally characterize optimized prototypes to compare with the models.
  • Efficiently work in a group to fulfill a short deadline.
  • Present decisions and results in terms of reports and presentations.

In the course an industrial partner will pose a technical challenge for sound propagation and effects in microacoustic devices. Students will work together in group projects to find solutions for the challenge. They will employ analytical and numerical methods to describe sound generation and propagation in order to find optimized design parameters. Proposed solutions will be evaluated in close cooperation with company engineers. Prototype designs can be realized using additive manufacturing.
