简要总结
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 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). 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 Sonova AG Headquarter based in Stäfa

结局指标
主要结局
Sound quality ratings
时间窗: 4 weeks
The sound quality ratings will be assessed with the aid of a Multi-Stimulus Test. The data, serving as the primary outcome measure, are collected in the laboratory and will use a continuous rating scale. The scale ranges from 0 "very bad" to 100 "very good" in increments of 1.
次要结局
- Oldenburg sentence test in noise(4 weeks)
- Oldenburg sentence test & manual tracking task(4 weeks)
- Adaptive Categorial Listening Effort Scaling (ACALES)(2 weeks)
- Self-report form(One week)
