Details and patient eligibility

About

A methodical evaluation of novel measurement and fitting methods for individualizing CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. The aim of the study is to investigate and asses strength and weaknesses of these novel measurement and fitting methods in terms of optimizing hearing performance and experience and/or usability of the hearing aids and accessories. Both laboratory measurements as well as evaluations in real life environments will be carried out. This will be a controlled and randomised active comparator clinical evaluation which will be conducted mono-centric at Sonova AG Headquarter based in Stäfa.
