Data in this chapter may be updated by a Medline search using the keywords: noise-induced hearing loss, diagnosis and management including prevention. Unfortunately, this produced a high yield but of relatively poor quality or narrow focus, thus most of the references have been hand-sourced from our personal collections on this subject. Also used are the references from the course ‘Medicolegal aspects of noise-induced hearing loss’ now run at the University of Southampton, and other references found during the course of our ongoing clinical and medicolegal practices.
