Hearing Aid with standard noise reduction (NR_1)
"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
"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
"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."
