中文摘要 | 噪音會造成聽力的損失,因此,對暴露在噪音環境之下的人員,必須提供耳塞 或耳罩等防護具,以保設聽力的健康。根據測試,耳罩可以比耳塞衰滅掉更高的音量,但 實際上,受到耳罩保護的人聽力不一定比戴耳塞的人好,也就是說實際上的防護效果,可 能耳塞較好,完全視佩戴防設具的方法與時機正確於否。本研究的目的,即以測量使用不 同防護具人員的聽力,來比較使用不同防護具後的防護效果。 研究對象為某靶場的受訓學員共161人,研究到最後僅有61人為合格對象。其中,分 配到耳塞組的有30人、耳塞加耳罩組有5人,無防護組有26人,研究過程中使用純音聽力 計共測量三次聽力。 結果發現,從開始受訓到結訓;不論那一組,三次的聽力檢查結果,都沒有顯示聽力 發生障礙。但打靶後的聽力,較打靶前為差;無防護組的聽力也較有防護的二組為差。故 射擊時,應配戴適當的防護具,以維設聽力健康。 |
英文摘要 | People exposure to noise environment is a cause of hearing loss. It is good for hearing health to use hearing protectors. The aim of the study was to understand the efficiency of hearing protectors. The conscripts were assigned to earplugs (30 persons) and earplugs combined with 'earmuff groups (5 persons), the other participated conscripts did not use any ear protectors (26 persons). The audiometric survey combined with questionnaires was conducted twice by the subjects. Among the subjects, hearing handicap was not found. The hearing threshold of subjects with protectors were lower than those without using ear protectors. There is no difference on hearing threshold between the two groups of protectors. According to the study results, it is efficacious for protection of hearing loss by using earplugs and earplugs combined with earmuff. The simplest and cheapest way is earplugs. |
