Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hearing Aid with beam form principle_A
Device: Hearing Aid beam former principle\_A (simulation of real ear condition). Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.
Bolero B90-SP
Behind the ear Hearing device fitted with an individual ear mold to compensate a Hearing loss
Hearing Aid with beam form principle_B
Device: Hearing Aid beam former principle\_B. Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.
Bolero B90-SP
Behind the ear Hearing device fitted with an individual ear mold to compensate a Hearing loss
Hearing Aid with beam form principle_C
Device: Hearing Aid beam former principle\_C. Each participant will be fitted with the 3 different beam former (directionality change) principles on the same hearing aid, saved to 3 manual programs. Beam former principle is a sound processing algorithm to focus to a target source in a noisy situation to improve the speech intelligibility and comfort. The experimental conditions vary in their parametrization to result in different degrees of beam forming and good speech quality.
