Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hearing Aid without NR and BF
Hearing Aid without Noise Reduction (NR) or beam forming (BF) enabled serves as reference condition.
Hearing Aid without NR and BF
Each participant will be fitted with the Noise Reduction (NR) and Beamforming (BF) disabled. Disabled means that no sound processing algorithm that removes noise from the speech signal is active.
Hearing Aid with NR
Hearing Aid with Noise Reduction (NR) enabled.
Hearing Aid with NR
Each participant will be fitted with the Noise Reduction (NR)(Sound Changing) program on the same hearing aid. Noise Reduction principle is a sound processing algorithm to remove noise from a speech signal to improve the speech intelligibility and comfort. The Noise Reduction is working spatially independent.
Hearing Aid with BF
Hearing Aid with beam forming (BF) enabled.
Hearing Aid with BF
Each participant will be fitted with a beam forming program on the same hearing aid. Beam forming (BF) principle is a sound processing algorithm to remove noise from certain directions to improve the speech intelligibility and comfort.
