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 sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Objective laboratory measurements will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa

Individual binaural Hearing abilities
Primary Outcome measurement is to measure the speech understanding in noise \[SNR in dB\] for the beam former principles A, B and C
Time frame: 2 weeks
Speechunderstanding for different beam form principles
Secondary Outcome measurement is to measure individual binaural Hearing abilities with psycho acoustical test principles (Binaural inter aural Level difference \[SNR in dB\] and Binaural Masking Level Difference \[SNR in dB\] and speech test \[Oldenburger Satztest in noise \[SNR in dB\]. Thereby, the correlation between psycho acoustical test results and speech test results will be analyzed.
Time frame: 2 weeks
