Everyone knows it: you meet with friends in a restaurant and despite the conversations of other guests, it is easy to understand each other. What is natural for people with normal hearing is a major problem for\r\n people with a cochlear implant (CI). Cochlear implants restore hearing to deaf people through direct stimulation of the auditory nerve. While speech comprehension works well in quiet situations, considerable background\r\n noise makes it impossible for CI wearers to understand the person they are talking to. <\/p>\r\n

In solchen Situationen können binaurale Signalverarbeitungsstrategien (BSS) das Sprachverstehen verbessern<\/em>. BSS nutzen auditorische Informationen der CIs, die zwischen beiden Ohren ausgetauscht werden. Aus ästhetischen Gründen kommt dafür nur eine drahtlose Verbindung infrage. Da Cochlea-Implantate jedoch Batterien zur Energieversorgung nutzen, ist die für den notwendigen Datenaustausch zur Verfügung stehende Energie stark limitiert. Zudem ist es notwendig, die Daten mit möglichst geringer Verzögerung zu übertragen, damit keine Echoeffekte auftreten und die BSS effizient eingesetzt werden können.<\/p>\r\n

Um das Problem geringer Latenz und niedriger Bit-Rate des Informationsaustausches zwischen CIs zu lösen, forschen Wissenschaftler des L3S<\/em> an einer Signalkompression<\/em>, die –  anders als übliche Kompressionsverfahren – nicht das Eingangssignal der Cochlea-Implantate nutzt, sondern bei den Erregungsmustern der CIs ansetzt, die in kompakter Form die wesentlichen Informationen des Höreindrucks enthalten.<\/p>\r\n

Die entwickelten Methoden werden gemeinsam mit dem Deutschen Hörzentrum Hannover<\/em> an CI-Nutzern erprobt und zukünftig im Verbund mit einer dort unter Leitung von Prof. Dr-Ing. Waldo Nogueira entwickelten BSS eingesetzt.<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n
