What defines deafness in the context of hearing impairments?

Deafness in the context of hearing impairments is defined as a loss that does not benefit from amplification. This means that individuals classified as deaf cannot achieve functional hearing levels through the use of hearing aids or other amplifying devices. In most cases, this level of hearing impairment can significantly affect communication, learning, and social interaction, necessitating alternative forms of communication and support.

The distinction of not benefiting from amplification is crucial, as it identifies the degree of hearing loss and shapes the strategies used for education and support. This definition acknowledges that while some individuals may have hearing loss that can be improved with technology, those who are deaf as defined here typically require different forms of communication support, such as sign language.

Other definitions, such as temporary hearing loss or those that can be medically treated, do not align with the understanding of deafness as they imply a potential for recovery or improvement. Similarly, an impairment that allows for some sound reception does not fit the definition of deafness, since it implies that some hearing abilities are present, which would categorize the individual differently.
