최근 소음문제가 큰 사회문제로 대두되고 있으며, 작업장에서 사용하는 에어노즐로부터 발생하는 소음이 작업환경을 저해하고, 그 소음강도가 작업자로 하여금 직업성 난청을 유발할 수 있는 위험수위에 있는 실정이다. 에어노즐은 사업장에서 사용할 경우 한 개씩 사용하는 경우가 매우 적고, 대부분 여러 개가 그룹으로 형성되거나 생산라인에 맞도록 조합하여 사용하기 때문에 고소음으로 인한 큰 피해를 유발하게 된다.(중략)

최근에는 산업장 근로자나 노인에게 주로 발생되던 청력손실이 청소년에까지 점차 확대되면서 청소년의 청력뿐 아니라 청소년의 청력에 영향을 미치는 여러 환경 및 요인에 대한 관심이 고조되고 있다. 그 중 외국어 공부나 음악감상용으로 청소년들 사이에 생활필수품처럼 널리 이용되고 있는 휴대용 카세트가 청소년의 소음성 난청원으로 매우 위험하다는 연구결과가 제시되어 학부모, 교사, 전문가에 의해 청소년 청력상태에 대한 조사와 청력손실을 유발하는 위험요인에 대해 많은 연구가 실시되었다. 청소년기에 취미/오락활동, 가정내 기계 기구, 음악, 교통 등의 소음에 상시적으로 노출될 수 있다. 직업적으로 소음에 노출된 적이 없는 청소년에게서 소음성 난청이 발생할 수 있다는 연구결과가 나오고 있는데, 청소년의 소음성 난청은 큰 소리를 내는 장난감과 개인용 음향기기, 콘서트장, 밴드활동 등의 음악과 관련이 있으며 이외에 모터사이클, 모터 스포츠 등의 레저 활동과 관련이 있다. 이러한 소음은 작업장 소음에 의한 초기 청력손실처럼 3~6 kHz 역의 청력손실을 특징적으로 보여준다. 이 글에서는 주요 취미활동과 관련하여 MP3 등 개인용 음향기기와 헤드셋 착용 근로자의 소음 노출 수준과 이에 따른 청력영향을 살펴보고, 소음저감방법에 대해 알아보고자 한다.

Dental professionals are exposed to various occupational risks, among which the problem of hearing damage has been newly revealed. There have been some researches reporting that noise occurring in a dental office exceeds the Occupational Safety and Health Act (OSHA) Standards. Especially, the pediatric dentists are repeatedly exposed to an additional noise source called the crying sound of children in addition to all kinds of noises from dental instruments. Accordingly, this study intended to investigate the noise environment likely to affect pediatric dentists and to examine the possibility of resultant hearing damages. The level of noise was measured respectively, when various dental instruments (ultrasonic scaler, high-speed handpiece, low-speed handpiece) are operated, when children are crying, and when both occasions take place simultaneously (from the distance of 30 cm) with a portable noise meter. And the daily duration of pediatric dentists exposed to the noise environment was surveyed. The results were compared with the standard value of noise threshold of NIOSH, OSHA, and that of hearing damage of CRA News letter respectively. Considering the intensity and exposure time, the noise environment of pediatric dentists exceeds the allowable noise threshold values. Even only one exposure to crying child was likely to lead to permanent hearing damage. Comparatively, pediatric dentists have a higher risk for occupational hearing damages, and some active measures are thought highly desirable to minimize it.

The noise levels on board ship recognized at Europe in the early 1970s and the noise regulations on board ship began to put in a statutory form. After that, in 1982 "International Code on Noise Levels on Board Ships" adopted by IMO and it became standard to the newly built ship and remain so to this day. Especially, the ship engine room, which have huge main engine and various kinds of subsidiary machines, is under an extremely loud condition and so the worker who works in it is easy to lose his hearing. Recently, each nation regulates the allowable noise exposure time by law to protect the industrial employee from the occupational hardness of hearing. In our country, the allowable noise exposure time is regulated by the labor standard law but the international provisions regulated by IMO have been applied in case of the ship engine room. In this paper, the cabin's noise levels of cargo-passenger ships plies south-west coast line were investigated.

치과임상에 있어서 약제, 재료, 기구 및 기타 부대시설과 치료실 환경은 오랫동안에 걸쳐 현금에 와서 놀라운 발전을 이룩하였음에도 치과의사가 시술중 받게되는 위해의 가능서은 아직도 여러곳에 상존하고 있는 실정이다. 의사가 늘 갖고 또 자신이 느껴야 되는 책임감에서 오는 긴장, 기계에서 오는 소음이 미치는 신체적영향 특히 청력과 관계되는 점 및 각종약제의 부작용 및 중독증, 그리고 치료중 예기치 않게 발생될 수 있는 환자로 부터오는 각종 감염, 도한 치과의사의 특수한 치료자세로부터 생기는 습관적인 정형외과적 문제와 정신적 육체적으로 겪게되는 격무로부터 오는 전신피로등의 문제를 어쩔수 없이 또는 치과의사 자신의 부주의로 당하고 있는 실례가 많다. 저자는 이 점에 대하여 위해가 생기는 문제를 항목별로 기술하면서 문헌적 고찰과 말레이시아의 치과의사 164명으로부터 설문을 통하여 수집한 사실의 통계를 분류하여 정리하고 그 예방 및 개선의 방법을 제시하면서 이는 치과의사뿐 아니라 종사자 전원이 숙지하여야 할 사실로 강조하였으며 가장 이상적인 치료실내의 치과의사용 의자를 고안하고 그 구조에 대하여 설명 하였다.

Purpose: The research were conducted to identify the knowledge, attitude and the preventive behaviour of noise according to noise-induced hearing loss prevention education and to provide primary data for effective noise-induced hearing loss prevention education for noise-exposed workers. Method: 104 noise-exposed workers were included in this study. The instrument used in this study was knowledge, attitude and preventive behavior of noise tool by Lee & Lee(1996). The first data were collected before the noise education from August to September, 2002. During 6 months, the education was provided, and then the second data were collected from April to May, 2003. Data were analyzed by SPSS 10.0 win program for finding frequency, percentage, mean, standard deviation, t-test, and ANOVA. Results: The results of this study were as follows: There were statistically significant differences of knowledge and attitude of noise related education level, and adhesion quality of wearing ear protection equipment after noise education. Also, otitis media's history, received education of the personal protective devices for the hearing conservation was significant in the preventive behaviour of noise. Conclusion: In conclusion, the noise-induced hearing loss prevention education was effective in changing the knowledge, attitude and the prevention behaviour of noise. Therefore, the noise-induced hearing loss prevention education is strongly recommended for noise-exposed workers and it will be necessary repeated education for changing prevention behaviour of noise.

For the purpose of finding how aircraft noise annoyance response is affected by variables when noise survey is performed, the questionnaire survey is conducted around the Gimpo International Airport in Seoul, Republic of Korea. This residential area is exposed to the aircraft noise and road traffic noise, simultaneously. Research areas are classified according to three different aircraft noise exposure levels expressed in WECPNL, under 75, between 75 and 80, and above 80 WECPNL, on aircraft noise map. The 7-step numerical magnitude with verbal category scales is used to measure the annoyance level. This survey suggests that aircraft noise annoyance is not affected to an important extent by other noise sources(road traffic noise, community noise) and demographic variables(sex, age, education, occupation, dwelling type, length of residence).
