Interventions

  • Hearing Aid with standard noise reduction (NR_1) — DEVICE
    Each participant will be fitted with the 3 different noise reduction (sound changing) principles on the same hearing aid, saved to 3 manual programs (ensures exact same hearing loss compensation for each intervention). Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. The active comparator condition is the state of the art Noise Reduction principle to mimic the natural directivity of the outer ear.
  • Hearing Aid with NR_2 — DEVICE
    Each participant will be fitted with the 3 different noise reduction (sound changing) principles on the same hearing aid, saved to 3 manual programs (ensures exact same hearing loss compensation for each intervention). Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of noise suppression and good speech quality.
  • Hearing Aid with NR_3 — DEVICE
    Each participant will be fitted with the 3 different noise reduction (sound changing) principles on the same hearing aid, saved to 3 manual programs (ensures exact same hearing loss compensation for each intervention). Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of noise suppression and good speech quality.

Study Details

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 novel sound changing principles in terms of hearing performance 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.
