Study of noise and hearing in the papermaking industry.
NIOSH 1983 Mar; :1-110
The National Institute for Occupational Safety and Health, Division of Biomedical and Behavioral Sciences (NIOSH, DBBS) surveyed a total of six paper mills in the southwest Ohio area. The survey consisted of the administration of hearing tests and questionnaires to volunteer employees as well as noise dosimetry on selected jobs within the paper industry. A total of 1,485 valid audiograms and 158 separate dosimeter samples on 21 different jobs were obtained. the audiograms and questionnaires were subjected to NIOSH's screening criteria to rule out hearing losses due to factors other than quantifiable exposures to occupational noise. Following the screening procedure a total of 158 males and 79 females remained in the sample. The dosimeter samples were separated into two groups. One group was of jobs whose mean noise levels were between 84 and 89 db(a) and the other group was of jobs whose mean noise levels were between 89 and 94 db(A). These two groups were compared to a group of employees who had either no or minimal exposure to occupational noise.
