A methodical evaluation of novel 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 assess strengths and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at the University Hospital of Zürich.

The focus is a comparison of hearing instrument algorithms on the auditory distance perception
University Hospital Zurich
Zurich, Switzerland
Success rate of the distance discrimination
Participants are asked whether an audio stimulus is closer or further at the end of the stimulus than at its beginning. The success rate is measured as a function of the test conditions.
