Objectives: The purpose of the study is to investigate the relationship between noise awareness, hearing ability, and dental hygieneperformance in dental hygienists. Methods: The subjects were 234 dental hygienists in Seoul, Gyeonggi-do, and Incheon. The questionnaire consisted of 3 questionsof general characteristics of the subjects, 1 question of noise awareness, 3 questions of hearing ability, 5 questions of dental hygieneperformance, 1 question of noise reduction necessity, and 2 questions of noise control. Noise awareness, dental hygiene performance,and noise reduction necessity were measured by Likert 5 scale. Cronbach’s alpha was 0.825 in dental hygiene performance reliability. Results: There was a significant difference in noise recognition by age(p<0.01) and working career(p<0.05). Those who pumped upthe higher TV volume accounted for 31.6% and 3.0% had hearing impairment in the regular health checkup. 3.4% of the respondentscomplained of hearing loss, ear fluid, and equilibrium problem diagnosed by the doctors. The relationship between the type ofworkplace environment and task performance showed a significant difference. Those who work in the dental hospitals had highscore of 3.43, while those who work in dental clinics had 3.20(p<0.05). The increased level of noise recognition affected the taskperformance and it is necessary to reduce the noise level. More try must be focused on the noise exposure prevention. Conclusions: In order to reduce the problems due to noise and improve their quality of life, it is necessary to change the noiserecognition in the work place.
