Impact and impulsive noise sources in American industry are discussed. Definitions and criteria for impact/impulsive noise are presented. Industrial sources (machines and processes) of impact/impulsive noise are listed. Censuses of six major categories of machine sources of impact/impulsive noise, categorized by the Standard Industrial Codes, and the corresponding censuses of workers having both direct and occasional exposure are described. The machine categories and their codes tabulated include: furniture and fixtures, primary metals, fabricated metal products, machinery (excluding electrical equipment), transportation equipment, and instruments. Exposure patterns resulting from impact/impulsive noise are discussed. The results of field observations of impact/impulsive noise exposure are tabulated. A tape library of impact/impulsive noise signals is described. The methodology, recording environment, and results of preliminary analysis of noise signals in the tape library are discussed. Appendices include an impact/impulsive noise bibliography that is based on an extensive survey of the literature, National Technical Information Service and EPA search word lists, and a glossary of noise source terms.
