Collaboration

Acoustic Technology and Centre for Acoustic-Mechanical Micro Systems carry out a considerable amount of research in cooperation with industrial partners in the form of Industrial PhD projects. Most of our MSc projects are carried out in cooperation with companies, and engineers and researchers from our industrial partners regularly appear as guest lecturers in our courses.

Significant industrial partners include the three Danish hearing aid companies, Oticon, Widex and GN ReSound, the electroacoustic industry, transducer manufacturers, Brüel & Kjær, engineering consultancies and members of GTS (advanced technology group).

A number of ongoing or recent industrial projects are listed below.
