    摘要(中) 台灣目前的工作環境裡,勞工因為工作而造成職業傷害的情況已相當嚴重,而其中又以營建業的勞工佔多數。由機械產生的工業噪音直接的危害作業勞工的健康,導致聽力上的受損。勞工安全衛生設施規則第300條規定:勞工每天工作八小時量平均;均能噪音量不得超過90分貝,而本研究主要在探討預拌混凝土廠與砂石場勞工噪音暴露的危害程度,是否有超過法規所規定,以及利用頻譜分析儀了解勞工在操作室所受到各頻率的噪音分貝值。為了暸解預拌混凝土廠與砂石場工作人員聽力損失危害程度,本研究透過(NIDCD) 美國國家耳聾與溝通障礙研究院所制定的勞工聽力是否有受損問卷調查表,針對現場操作人員進行問卷訪談調查,再由實地測量結果與問卷調查進行交叉分析。並且經由中部一間預拌混凝土廠中內設有遠端控制進行量測,探討是否能有效將低分貝量,並提出噪音防護建議,以供行政措施及衛生教育之參考。
      噪音環測結果顯示,預拌混凝土廠及砂石場八個小時均能噪音量為88.7±2.2分貝及75.5±1.8分貝。雖然噪音量皆符合法規規定,但在低頻噪音部份卻是國內沒有深入做探討之處,惟經由問卷調查結果顯示勞工已經有聽力受損的情況,表示現階段法規值尚有探討之必要。
      在本研究經過遠端控制系統量測結果顯示,噪音量確實能有降低在15分貝以下,並且在各國法規值中低頻部份也能有效降低,而勞工個人防護具稽核結果也顯示勞工在安全教育訓練方面的不足。在國內越來越重視勞工安全的情況下,為了減少勞工聽力上的損失以及避免勞工暴露在噪音源下,可從遠端控制以及規劃工作動線、教育訓練、個人防音護具配戴稽核等行政管理進行改善。
    摘要(英) At present, it is very serious in Taiwan working environments that labors have occupational injuries caused by their jobs. Among them, those labors working in the construction industry are in the majority. The industry noise resulted from machines will directly endanger the health of working labors, causing hearing losses. According to the Article 300 of the Rules of Labor Safety and Health Facilities, the time weighted average for the working time of a labor is eight hours per day and the equivalent noise level shall not be more than 90 decibels. This research is designed to study if the damage of noise exposures for the labors in ready-mixed concrete plants and gravel processing plants exceeds the limit regulated by laws and to take use of the spectrum analyzer to understand the level of various frequency noises for a labor working in the operation room. In order to understand the hearing loss level of those workers in ready-mixed concrete plants and gravel processing plants, this research adopts the questionnaire about the hearing loss of labors drawn up by the National Institute on Deafness and Other Communication Disorders (NIDCD) to make an interview with operating workers on site. And, this research then makes a cross analysis of on-site measurement results and questionnaires. With the remote-control measurement set in a ready-mixed concrete plant in Central Taiwan, this research can study if it is possible to lower the noise level efficiently and provide a suggestion for protections against noises as a reference resource of administrative measures and health educations.
    The result of environmental test on noises shows that the equivalent noise level of ready-mixed concrete plants and gravel processing plants for eight hours is 88.7±2.2 decibels and 75.5±1.8 decibels respectively. Although their noise levels are in conformity with the laws & regulations, there is not any further study on low-frequency noises in Taiwan. Only with the questionnaire, the result reveals that some labors have hearings losses already, showing that it is still necessary to study the existing level regulated by laws.
    With the measurement by a remote-control system, the result shows that the noise level can be exactly reduced to 15 decibels below and the low-frequency noise level regulated by laws in each country is also able to be reduced efficiently. And the result of inspections & examinations for personal labor protection equipments also shows that it is insufficient for the labors in the safety educations and trainings. In domestic, the labor safety is taken more and more seriously. In order to reduce the hearing loss of labors and to prevent labors from exposing to the noise source, we can improve such administrative managements as remote control, move line planning, educational training and personal protection equipment examination.
