Summary
Brief summary
This early feasibility study aims to collect pilot data on impedance measurements in
real-world environments and to collect real-world and difficult listening situations and the
factors impacting this, reflecting situations the subjects encounter during their daily life
outside of the clinic. Improving the monitoring of both aspects may lead to improvements in
monitoring and personalising the fitting to optimise hearing outcomes for persons with a
cochlear implant.
