Onset time refers to the onset time of profound deafness (early: deafness begun in childhood, but after the development of spoken language (thus postlingually); congenital and progressive: the subject had a hearing loss at birth, but was hearing-aid fitted when 10-years old as the hearing-loss worsened).
