An interventional study of several virtual 3-D complex audio environments in Ability, Spatial, sponsored by Sonova AG. Completed at 1 site in Switzerland. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2018-12-06.
Sponsored by Sonova AG · Not applicable, Interventional, and Other
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.

Exclusion Criteria:
normal hearing participants with and without hearing aids
Procedure: several virtual 3-D complex audio environments
The focus is a comparison of four virtual 3-D complex audio environments with regard to the sensitivity of hearing aid algorithms.
Head movements measured with head tracker
The participant starts the acoustic stimulus, tries to identify the direction of the stimulus as precise as possible and validates the final position. This is interpreted as reaction time with regard to spatial quality in seconds \[s\].
Time frame: 6 weeks
