The Department of Electrical Engineering and the Centre for Acoustic-Mechanical Microsystems (CAMM) invite highly motivated and talented graduates to apply for a 3-year PhD where you will study porous materials and their application in hearing aids. CAMM facilitates and connects research in acoustic-mechanical interaction, numerical methods, optimization, materials, microfabrication and acoustic measurement techniques. You will build new knowledge based on the expertise of the three world-leading Danish companies in hearing aids, together with the strong research background from DTU Electrical Engineering and DTU Mechanical Engineering.
The mechanical properties of the internal solid structure and the acoustic-mechanical interaction with a fluid determine the behaviour of porous materials when exposed to sound and vibration. Porous materials include foams, fibre materials and woven/unwoven fabrics, and have multiple applications in sound and vibration control. An elastic frame can provide them with mechanical stability when exposed to vibration. In this project you will acquire in-depth understanding of the vibroacoustic behaviour of porous materials used in hearing aids (HAs). You will explore alternative designs, materials, and fabrication techniques that can enhance their performance. You will benefit from the knowledge and tools available at CAMM to push the boundaries of this innovative research field.
Responsibilities and qualifications
In this project you will learn and apply theoretical and experimental methods and techniques to study and characterize sound and vibration absorbing materials on the millimetre scale. It expected that this project will lead to practical advances in the design of HAs. Depending on your interests and competencies, this will involve your engagement in:
- Increasing the fundamental understanding of porous materials and foams at the scale of hearing aids within the range of audible frequencies.
- Creating suitable analytical and numerical models, including acoustic-mechanical coupling, viscous and thermal losses, and material damping.
- Mastering and developing mechanical and acoustic measurement techniques to assess the vibroacoustic properties and performance of porous materials on the millimetre scale.
- Mastering and developing fabrication processes leading to materials with improved performance.
- Integration of novel solutions with transducers, electronics, and housing of the HA.
Prior experience within one or more of these areas is considered beneficial to your application. For these tasks you will take responsibility for project planning, data management, lab work such as fabrication and setting up and running experiments, and comprehensive documentation. You are also expected to be able to work in a highly collaborative environment inside CAMM and in close contact with our company partners. Close exchange between DTU Electrical Engineering and DTU Mechanical Engineering is expected. Fluent written and spoken English is essential.
Your PhD project will result in scientific publications of your results. You will present at international conferences as part of your research training and you can also sharpen your didactics skills through experience as teaching assistant.
As a PhD student in CAMM and the Acoustics Technology Group, you will:
- Be a part of a creative and stimulating scientific environment
- Develop your theoretical and experimental skills
- Collaborate with experts in topics related to your project
