摘要

Excessive noise is a global occupational health hazard with considerable social and physiological impact,including noise-induced hearing loss (NIHL) (Nelson et al., 2005). Noise is one of the most commonoccupational hazards in American workplaces. This study was performed in the Occupational Safety andErgonomics Program’s Biomechanics Laboratory at Auburn University. The main purpose of this studywas to compare the noise levels made by different air nozzles actually used by a bakery facility to nozzleswhose manufacturers purported that they produce significantly less noise. Noise levels were determinedusing a sound level meter, which was positioned at ear level at distances of 5 and 10 feet. At the factory, airpressure (~100 psi) was used to push product downstream and to speed product cooling. The nozzles usedwere simple pipes or traditional air nozzles with side venting, but not of a “low noise” design. Two nozzlesused by the factory were compared to three quieter nozzles. Nozzles were tested for both noise level andfor air pressure (pushing force).
