Exploration of the Functional Effect of Modified Gain Precalculation on Soft Speech Intelligibility
Sponsor: Sebastian Griepentrog
Summary
An exploratory investigation of gain precalculation principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These gain precalculation principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and assess strength and weaknesses of these gain precalculation principles in terms of speech intelligibility to determine their application in hearing instruments (Phase of development). Objective laboratory measurements as well as subjective ratings will be carried out. This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.

Conditions
Interventions
Competitor device, hearing aid with standard gain precalculation principle
Each participant will be fitted with two different pairs of hearing aids with different gain precalculation principles. Gain precalculation applies the amplification of sound signals in the hearing aid. The active comparator condition is the state of the art hearing aid gain precalculation from a competitor device.
Hearing aid with gain precalculation principle 1
Each participant will be fitted with two different pairs of hearing aids with different gain precalculation principles. Gain precalculation applies the amplification of sound signals in the hearing aid. The experimental conditions vary in their parametrization to result in different degrees of added amplification.
Hearing aid with gain precalculation principle 2
Each participant will be fitted with two different pairs of hearing aids with different gain precalculation principles. Gain precalculation applies the amplification of sound signals in the hearing aid. The experimental conditions vary in their parametrization to result in different degrees of added amplification.
