Availability: Institute of Noise Control Engineering Iowa State University, 210 Marston Hall Abstract: This paper summarizes a student term project that was conducted as a part of a two quarter sequence acoustics course, which is one of the projects sponsored by the National Institute for Occupational Safety and Health (NIOSH). The construction tools selected are, an electric impact wrench and a jig saw, specifically DeWalt DW290 and DW321. Various studies have shown that almost 60% of workers suffer significant noise induced hearing loss (NIHL) as a result of work related noise. Power tools have been shown to be a major contributor to construction noise. Studies have also shown general noise exposure from portable power tools to range from 85dBA to 110 dB. Unlike the EC nations or Japan, the United States does not have specific legislation that mandates manufacturers to minimize NIHL risk and to declare noise level information, thus the noise level of a tool is not given the high priority which it deserves.
