My father died before passage of the Americans with Disabilities Act, landmark legislation passed in 1990 that requires public facilities, including work places, to provide reasonable accommodations for people with disabilities. Like most people of his generation and many today, my father did not discuss the problems that his hearing loss caused for him. It was a burden that he kept to himself and, consequently, one that I did not understand until I was faced with it myself in my mid-30s, the age when my own hearing changed so dramatically.
