摘要


鞭炮的噪音十分巨大,乃無庸置疑之事實。本研究測量6種鞭炮,分別在2m,4m與6m的距離爆炸時所產生的噪音量,發現鞭炮的噪音竟達130 dBA,有可能造成永久性的聽力喪失。文中並報告2名因鞭炮造成聽性外傷的實例,其聽力喪失均屬不可逆。鑑於鞭炮對於聽器的危害,實有必要立法禁止燃放。

Six kinds of commercially available firecrackers were squibbed at a distance of 2,4,and 6 meters, respectively, for measuring noise level by a sound level meter (Rion NA-24). As a result, noise level varying from 107 dBA to scale-out (greater than 130 dBA) was obtained in each of the firecrackers. Once noise level exceeds 130 dBA, permanent hearing loss is thus unavoidable, as presented in 2 clinical patients. Besides hearing loss, firecrackers can also cause burn, eye injury, and respiratory problem. It is therefore recommended that firecrackers should be prohibited from squibbing.
