NCT03699735

Brief Summary

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

Conditions

Outcome Measures

Primary Outcomes (1)

  • 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

    2 weeks

Secondary Outcomes (1)

  • Speechunderstanding for different beam form principles

    2 weeks

Study Arms (3)

Hearing Aid with beam form principle_A

ACTIVE COMPARATOR

Device: Hearing Aid beam former principle\_A (simulation of real ear condition). Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.

Device: Bolero B90-SP

Hearing Aid with beam form principle_B

EXPERIMENTAL

Device: Hearing Aid beam former principle\_B. Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.

Device: Bolero B90-SP

Hearing Aid with beam form principle_C

EXPERIMENTAL

Device: Hearing Aid beam former principle\_C. Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.
