PhD scholarship in Vibroacoustic Characterization and Modeling of Balanced Armature Receivers in Hearing Aids


Apply for a 3-year PhD position at Technical University of Denmark (DTU)with the collaboration of The Departments of Electrical Engineering and Mechanical Engineering, and the Centre for Acoustic-Mechanical Microsystems (CAMM). highly motivated and talented graduates are envourged to apply where they will be able to conduct  in-depth research on hearing aid (HA) receivers. CAMM combines expertise in electroacoustics, numerical methods, acoustic-mechanical coupling, optimization, materials and fabrication, and measurement techniques

The Technical University of Denmark(DTU)

DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Research Includes:

You will examine in detail all aspects of the following:

  • HA receivers:
  • Dynamic mechanical and acoustical behavior,
  • Magnetic circuits and materials, and electrical circuitry

you may also explore more radical, novel transduction concepts for HA receivers.Your research will also include:

  • Electroacoustic characterization of a (dual) balanced armature transducer, including time and frequency responses, efficiency, feedback, and distortion.
  • Mechanical-acoustic characterization of transducer performance in hearing aids.
  • Advanced numerical simulation coupling electromagnetic, mechanical and acoustic domains.
  • Preparation of representative analytical models, such as lumped electro-mechanical-acoustical models, with a basis on the detailed physical behavior.
  • Practical measurements of the performance of receivers, as a validation for the models and additional insight.
  • Investigation of alternative transduction principles and designs that can be used in HA receivers. This may include the use of numerical optimization tools available at CAMM.
