Spatial impression for individual listeners

Wednesday 05 Nov 14
The Hearing Systems researchers are all involved in several networks, such as EU- networks, collaboration with industrial partners, audiological clinics and also the Danish Sound Innovation Network.

Last year at the CAHR Presentation Day when Johannes Käsbach presented new results from his PhD one of the researchers at the hearing aid company Widex, Morten Løve Jepsen, who also is a former PhD from Hearing Systems and still involved in some PhD projects at DTU, approached him afterwards.

“My PhD project deals with the spatial perception of sounds, and Morten Løve Jepsen knew about other studies in this field concerning hearing aids. He asked me if I would be interested in doing a project together on investigating how spatial perception might be altered for hearing aid users,” Johannes explains.

The concept of projects supported by the Danish Sound Innovation Network is that one university and two industrial partners will be involved. Johannes thought about who else might be interested and came up with the idea to contact Bang & Olufsen.
“They are experts in producing Hi-Fi systems and perform as well research in sound perception. So together we set up a project with the goal to investigate spatial perception not only for normal hearing people, but also hearing impaired people. To do this I use loudspeakers in order to create a certain spatial impression at the listener’s ears, but you can also use a hearing device like head phones or in this case hearing aids. In that sense we combine a certain spatial impression for the listener. Because why shouldn’t hearing impaired listeners get the chance to get a good sound?” Johannes Käsbach says.

The idea behind the Danish Sound Innovation Network is that the projects are applied research with the aim to explore technologies and to open the way for innovative product development with the possibility to even generate new start-ups.
