Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application

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

Design Details

  • Primary Purpose: TREATMENT
  • Allocation: RANDOMIZED
  • Interventional Model: CROSSOVER
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
ACTIVE_COMPARATOR: Hearing Aid with beam form principle_A
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.
Behind the ear Hearing device fitted with an individual ear mold to compensate a Hearing loss
EXPERIMENTAL: Hearing Aid with beam form principle_B
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.

EXPERIMENTAL: Hearing Aid with beam form principle_C
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Individual binaural Hearing abilities
Time Frame: 2 weeks
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Speechunderstanding for different beam form principles
Time Frame: 2 weeks
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.
