GN ReSound, Oticon and Widex in cooperation with the Technical University of Denmark (DTU) have opened the research centre ‘Centre for Acoustic-Mechanical Micro Systems’ (CAMM). One of CAMM’s key focus areas is to study how the acoustic signal influences a mechanical construction and vice versa. This can lead to designing smaller hearing aids with an improved sound experience for hearing aid users.

Studies at CAMM will include analyses of acoustic capacities of a design under the influence of wind, and how design alterations can optimise sound and eliminate unwanted wind noise. Projects will also evaluate the best shapes and constructions for improving the transmission of sound as well as develop and explore new materials and processes as alternatives to plastics. Furthermore, CAMM researchers will examine different designs and the interaction between acoustic - and mechanical parameters to limit feedback in hearing aids. The manufacturers expect CAMM to become a solid platform for potential product development through the research centre’s findings and its future candidates’ professional knowledge.

Professor Jakob Søndergaard Jensen is leading the research centre, and he has a focus on creating a unique research and educational platform to develop acoustic and mechanical microsystems. Jakob Søndergaard Jensen states, “With CAMM we get an amazing opportunity to create a unique research environment - we become one of the first research centres in the world with dedicated efforts in this field. With international top-class research and education we will contribute to strengthening Danish companies’ leading position within developing products that depend on the interplay between mechanics and acoustics - such as hearing aids”. It is expected that CAMM will consist of a group of 10-15 scientists, among these postdocs and PhD students. CAMM will also offer a number of courses at bachelor, master and PhD level.
