Deafness

The word deaf is used in a different way in different contexts, and there is some controversy over its meaning and implications. In scientific and medical terms, deafness normally refers to a physical condition characterized by lack of sensitivity to sound. Notated as deaf with a lowercase d, this refers to the audiological experience of someone who is partly or wholly lacking hearing In legal terms, deafness is defined by degree of hearing loss. These degrees include profound or total deafness (90 dB - 120 dB or more of hearing loss), severe (60 dB - 90 dB), moderate (30 dB - 60 dB), and mild deafness(10 dB - 30 dB of hearing loss). Both severe and moderate deafness can be referred to as partial deafness or as hard of hearing, while mild deafness is usually called hard of hearing.
Within the Deaf community, the term "Deaf" is often capitalized when written, and it refers to a tight-knit cultural group of people whose primary language is signed, and who practice social & cultural norms which are different from those of the surrounding hearing community. This community does not mechanically include all those who are clinically or legally deaf, nor does it exclude every hearing person. According to Baker & Padden, it includes any person or persons who "identifies him/herself as a member of the Deaf community, and other members accept that person as a part of the community"
