Evaluation and Optimization of Hearing Devices in 3-D Complex Audio Environments Study 3
Evaluation and Optimization of Hearing Devices in 3-D Complex Audio Environments Study 3
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.
Participants fulfilling any of the following inclusion criteria are eligible for the study:
Normal hearing participants
• Adult persons with audiometric normal hearing thresholds
Hearing impaired participants
The presence of any one of the following exclusion criteria will lead to exclusion of the participant:
