About the study
People with hearing loss experience extra effort when listening, which can lead to severe psychological barriers to communication and social participation. Listening effort can lead to fatigue, mental strain, burnout, medical sick leave, and the need for increased time to recover from regular daily activities. This proposal aims to understand effort changes on a moment-to-moment basis during listening, how long the effort lasts, and how the planning and execution of effort is impacted by the experience of using a cochlear implant.
