Hearing restoration refers to various methods and technologies aimed at improving or recovering hearing abilities in individuals with hearing loss. This can include the use of devices like hearing aids and cochlear implants, which amplify sound or directly stimulate the auditory nerve, respectively. In addition to devices, hearing restoration may involve medical treatments, such as surgery for certain conditions or therapies that help retrain the brain to process sound. Research is ongoing in areas like gene therapy and stem cell therapy, which hold potential for future advancements in restoring hearing function.
