Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hearing Aid without NR enabled.
Hearing Aid without Noise Reduction (NR) enabled serves as reference condition.
Hearing Aid without NR enabled
Each participant will be fitted with noise reduction disabled. Disabled means that no sound processing algorithm that removes noise from the speech signal is active.
Hearing Aid with NR(1)
Hearing Aid with Noise Reduction I (NR) enabled.
Hearing Aid with NR(1)
Each participant will be fitted with the noise reduction program on the same hearing aid. The principle of the noise reduction algorithm is to remove noise from a speech signal with the aim of improving the speech intelligibility and comfort.
Hearing Aid with NR(2)
Hearing Aid with Noise Reduction II (NR) enabled.
Hearing Aid with NR(2)
Each participant will be fitted with a second noise reduction program on the same hearing aid. The parameterization of this NR algorithm differs from that in NR(1).
