Northwestern University is the source for this information.

Summary: Hearing loss caused by aging, noise, and certain cancer medications is irreversible because scientists haven’t been able to reprogram existing cells to develop into the outer and inner ear sensory cells, which are necessary for hearing. However, scientists have recently uncovered a single master gene that divides ear hair cells into outer and inner cells, removing a major roadblock to the formation of these cells for hearing restoration.
