Abstract
The exact cochlear transmission mechanisms of bone conduction stimulation are unknown. Standard stapes velocity measurements, however, are insufficient to disentangle these complex mechanisms. Differential cochlear pressure has been found to be a good estimation of the cochlear input and is therefore a suitable measurement to study the cochlear mechanics involved in bone conduction transmission. I will discuss a special test-setup that was further established and validated during my PhD-project. Using commercial fiber-optic pressure sensors, the differential pressure across the cochlear partition in human cadaveric temporal bones was measured during bone conduction stimulation. Results of this first study will be presented during the presentation. In addition, I will also present some preliminary results of an ongoing study on human fresh-frozen cadaveric heads, in which a novel active transcutaneous bone conduction implant is characterized in terms of output and implant location. Furthermore, I will give an overview of future steps and planned milestones.
