ProblemThe hearing impaired have a difficult time

communicating with individuals that do not know sign language.

These difficulties can cause a hearing impaired individual to limit their activities in order to avoid frustrations and embarrassment.

Ten million Americans are hard of hearing and one million are functionally deaf. (Mitchell 2005)
