This stud was carried out to evaluate health effects of noise using THI(Todai Health Index) from July 15 to August 30, 2001, 696 industrial workers whose health was managed by korea industrial Health Association were selected as subject of this study. The results were as follows ;
1. Study subjects, 696 workers, were divided into three groups, non-exposure group, 85-99dB group and 100dB≤group. the group who was exposed to high noise level(100dB(A)≤) showed the higher complain level than the other two groups who were exposed to less than 100dB(A).
2. Workers exposed to more than 100dB(A) displayed significantly different complaint level in aggressiveness scale, digestive scale and nervousness scale.
3. Depending on complaint level by all characteristics and noise level, workers exposed to more than 100dB(A) showed higher level in high aged workers, female, those who worked for a long time, heavy drinker, and heavy smoker and sitting workers.
Form the results, we suggest that industrial hygienists have to formulate a comprehensive health management system for high level noise exposure workers included good life style, mental health, and noise deafness protection measures in order to technically control the health of noise exposure workers.
