The Hearing Loss Prevention Team of NIOSH was invited to be the technical advisor in a study of an advanced hearing protector at a facility of a major auto manufacturer. The study consisted of four visits over the course of one year. Subjects were assigned to one of three groups: Group A received the new hearing protector, Group B was counseled in the proper wear of their current hearing protector, and Group C was not counseled. At the first visit all groups filled out a hearing health questionnaire, a comfort survey (based on Parks and Casali), an attitudes and beliefs survey (based on Stephenson) and appropriate consent forms. They also received a puretone audiogram and a Fit Test. Except for the audiogram and hearing health questionnaire, the same information was collected during the subsequent visits at one month and 6 months. The previous information plus audiograms were collected at 12 months.
