This chapter provides background information for researchers who wish to become familiar with some basic medical and audiological aspects of hearing loss and the technology of hearing aids. It introduces (1) the disciplines involved in research on hearing loss, (2) the medical categories of hearing loss and their various effects on communication, (3) the different degrees of hearing loss as defined by different national and international organizations, (4) statistics on the preva- lence of hearing loss worldwide, (5) some technological aspects of hearing instruments, (6) sta- tistics on non-usage of hearing instruments worldwide, and (7) barriers to using hearing aids. Since hearing loss is a worldwide pervasive phenomenon which is likely to increase even further in the future, the authors point out that an understanding of the non-use of hearing aids is crucial.
