A methodical evaluation of sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and asses strength and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Objective laboratory measurements as well as subjective ratings will be carried out. This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
