A considerable part of Acoustic Technology's research is carried out in cooperation with industrial partners, for example 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 electroacoustic industry, transducer manufacturers, Brüel & Kjær, the three Danish hearing aid companies, Oticon, Widex and ReSound, engineering consultancies, and members of GTS (advanced technology group).
A number of ongoing or recent collaboration projects are listed below.
