Hearing Aid without NR
Hearing Aid without Noise Reduction (NR) serves as reference condition.
Hearing Aid without 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.
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_A
NR\_A: Noise Reduction principle A
Hearing Aid with NR_A
Each participant will be fitted with the 4 different Noise Reduction (Sound Changing) principles on the same hearing aid, saved to 4 manual programs.

Hearing Aid with NR_B
NR\_B: Noise Reduction principle B.
Hearing Aid with NR_B
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 vary in their parametrization to result in different degrees of noise suppression and good speech quality.
Hearing Aid with NR_C
NR\_C: Noise Reduction principle C.
Hearing Aid with NR_C
