Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application - 2019_20

Hearing Aid with standard Noise Reduction (NR) Each participant will be fitted with the 4 different Noise Reduction (Sound Changing) principles on the same hearing aid, saved to 4 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.

Each participant will be fitted with the 4 different Noise Reduction (Sound Changing) principles on the same hearing aid, saved to 4 manual programs. 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 (novel NR principle) vary in their parametrization to result in different degrees of noise suppression and good speech quality.

Each participant will be fitted with the 4 different Noise Reduction (Sound Changing) principles on the same hearing aid, saved to 4 manual programs. Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. This experimental condition combines standard NR and novel NR principle to result in different degrees of noise suppression and good speech quality.
