Users' Perspectives on Closest to Natural Hearing

Hannah McPierzie is an international disability advocate, speaker, and consultant who joins us in the studio to discuss Neurofibromatosis Type 2 (NF2), its far-reaching consequences, and the complex decisions individuals and families may face following diagnosis. Drawing on both her professional and lived experience, Hannah shares her journey with NF2, including the progression of hearing loss, her experience with auditory brainstem implants (ABIs), and the process of navigating a dual sensory loss. She offers valuable insights into self-advocacy, communication accessibility, and what it means to identify as deaf-blind.
