Abstract
Workers at drill sites are among the millions of employees in the United States regularly exposed to high levels of noise on the job. Many of these persons regard noise as a nuisance rather than an occupational hazard. NIOSH-PRL chose an administrative approach to address this issue and has developed an invisible ink training exercise called Drill Rig Incident. The goal of the exercise is to inform workers about noise, hearing loss, and hearing protection. The training exercise begins with background information and a problem. The problem is systematically resolved as information is revealed in a series of 11 questions, each with several choices of answers. Responses to each choice are printed within brackets using special ink. Trainees choose their response and draw a special ink developing pen between corresponding brackets on an answer sheet. Words appear that provide feedback about whether or not the answers they selected are correct. The effectiveness of the training exercise was evaluated using a split-group, pretest-posttest experiment and a self-reporting measure. Subjects were randomly assigned to either a pretest or a posttest group. They were tested before or after the intervention to determine if the objectives of the instruction were achieved. Results indicated that subjects scored significantly higher in the posttest. An eight-item, Likert-scale, self-reporting measure was used to determine validity and utility of the exercise. Over 73% of the subjects indicated that they "learned something new from the exercise," and nearly 90% said they "will use some of the ideas presented to protect their hearing." The utility of the exercise was high, as almost 90% of the subjects reported that "the way the material was presented is a good way for me to learn."
