Evaluation of high sound level pressure on human error rate, by using ergonomic test of Two-hand coordination in textile industry in ghaem baft textile in 2012
Introduction: in textile industry noise has been a significant source of physical and psychological stress. Noise has broad effects on mental and physical health. Another interest aspect of no auditory effect is the effects of noise on performance, such as information processing, error rate, attention, and memory. In hand working due to the degradation of working memory and distraction of attention away from the task at hand, noise maybe affect performance. The aim of this study is to objectively demonstrate the effect of noise on, error rate, speed response and Performance in textile industry workers. Methods: this clinical study was conducted among 72 workers that have been selected based on stratification to match age and work experience of two noise sections (spanning and weaving) as case group and office workers as control group. Participant who had a history of arthritis or other muscle-related discomfort in the hands or shoulders and also participant with loss hearing were excluded from this study. For measurement work performance two hand coordination tests was used. Measurement by two hand coordination was performed in five times during shift work. The error rate was the main variable in this measurement.
