Professionals in the field of hearing;

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.
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."
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”
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.
