Although the adverse effects of occupationally associated noise on hearing have been well documented, review of the recent literature revealed few studies which have carefully measured the role of non-occupational loud sound in sensorineural hearing loss. This thesis will measure the strength of association of sensorineural deafness and avocational noise by calculating the odds ratio in a case-comparison design. The prevalence of avocational loud noise activities of a group of 200 cases diagnosed as having sensorineural deafness at retirement from the United States Air Force will be compared with the prevalence of avocational loud noise activities of a group with the prevalence of avocational loud noise activities of a group of non-deaf Air Force retirees who hace been matched for age, service occupation, family history of hearing loss, personal history of hearing loss and known causes of otic dysfunction. Limitations of the study and anticipated results are discussed.
