How were members of the target audience involved in this development?
von Häfen: The OpenEar team had access to a large number of test subjects. In addition to the live tests and workshops, more than 50 cochlear implant users joined us at the sound laboratory and were able to give us crucial indications of sound improvements. Thanks to the support of cochlear implant and hearing aid users, the filter cascade was extended to live concert settings and has since been used in numerous professional performances. Joint listening experiences were implemented at the Theater Koblenz, the Rhein-Mosel-Hall, and even more intimate venues like chamber music halls or several auditoriums.
Right now we are in the process of expanding and adapting the technology to different devices or media platforms. We are confident that we will be able to achieve great things in this area for cochlear implant and hearing aid users in the near future.
