Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hearing Aid standard NR_1
Hearing Aid with standard Noise Reduction (NR) serves as reference condition.
Hearing Aid with standard Noise Reduction (NR_1)
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.
Hearing Aid with NR_2
NR\_2: Noise Reduction principle 2
Hearing Aid with NR_2
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.
Hearing Aid with NR_3
NR\_3: Noise Reduction principle 3
Hearing Aid with NR_3
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.
Hearing Aid with NR_4
NR\_4: Noise Reduction principle 4
Hearing Aid with NR_4
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.
