Assessing Listening Effort at Different Signal-to-noise Ratios in Bone-anchored Users

Bone-anchored hearing systems (BAHS) use the body's natural ability to transfer sound through bone conduction. The sound processor picks up sound and converts it into vibrations that are transferred through the skull bone to the inner ear (cochlea). Thus, for patients with conductive or mixed hearing losses, patients with lasting hearing loss following a middle ear disease or malformations (such as microtia), the vibrations are bypassing the conductive problem in the ear canal or middle ear. The intervention in this study is audiologically fitting one/two bone-anchored sound processors (Ponto 4) to patients that are already implanted with abutments.
