A: No. It depends on the Deaf person's hearing level, and other factors. Some people who are severely or profoundly deaf like to wear aids to give them more environmental awareness, even though they may not be able to participate in a spoken conversation. Others who are equally deaf don’t wear aids at all, since they don’t derive much benefit from them, don’t feel comfortable, or simply don’t want to bother with them. Deaf people can function quite nicely without aids. It’s a matter of personal preference.
