Abstract
Attitude change was studied in an Industrial Hearing Conservation Program. Persuasive communications were presented to a group of 117 bottling workers in a Brewery in the Midwest. These took the form of management directives, educational presentations and individual audiometric testing. All workers were observed for a period of two weeks following the audiometric test and those wearing hearing protection, both before and after the test were compared to those not wearing protection, on the basis of age, years of experience and degree of impairment. The individual persuasive communication in the setting of the test was found to be a significant factor in increasing compliance behavior to the rule making hearing protection mandatory in the workplace.
