某型导弹发射时脉冲噪声对射手听觉器官危险性的评价

THE RISK ASSESSMENT OF AUDITORY DAMAGE FOR THE OPERATORS PRODUCED BY IMPULSE NOISE FIRED FROM CERTAIN MODEL MISSILE

研究监测了某型导弹发射时脉冲噪声参数，检查了暴露于脉冲噪声豚鼠的听觉损伤，并以ＧＪＢ１２－８４脉冲噪声损伤危险标准及豚鼠听觉损伤为依据评价了该导弹发射时对射手的听觉危险度。结果显示，发射不超过４次，听觉不会损伤。

In the study,the parameters of impulse noise by certain model of missile fired were measured, and the auditory damage in guinea pigs were examined after impulse noise exposure. According to the formula of GJB 12-84 criterion and degrees of the auditory damage in guinea pigs, the auditory risk produced by missile for the operators was assessed. It is believed that the auditory damage will not occur within four rounds of impulses. To ensure safety,it′s suggested for the operators to wear an ear defender
