About Hearing Loss Impairments in hearing can happen
in either frequency or intensity, or both. Hearing loss
severity is based on how well a person can hear the
frequencies or intensities most often associated with speech.
Severity can be described as mild, moderate, severe, or
profound. The term “deaf” is sometimes used to describe
someone who has an approximately 90 dB or greater hearing loss
or who cannot use hearing to process speech and language
information, even with the use of hearing aids. The term “hard
of hearing” is sometimes used to describe people who have a
less severe hearing loss than deafness.
