2 Deafness and Hearing Loss What is deafness? What do you think it means to be deaf? Write a 1-2 sentence definition

3 Definitions of Deafness Webster’s dictionary defines deaf as totally or partially unable to hear Professionals in the field of hearing; audiologists, ear, nose, and throat physicians, or hearing aid dispensers, normally address the term deaf or deafness to mean someone who is not able to hear and understand speech no matter how loud it is.

4 Definitions of Deafness The Individuals with Disabilities Education Act (IDEA) defines deafness as "a hearing impairment that is so severe that the child is impaired in processing linguistic information through hearing, with or without amplification."

5 Definitions of Deafness From Office of Special Education: “Deafness is a hearing impairment which is so severe that the child's hearing, with amplified sound, is nonfunctional for the purposes of educational performance”

6 Definitions of Deafness This is a disability that is multi-dimensional Depending on the author of the definition and their perspective (educational, medical, audiological, etc), the definition will differ.
