摘要
本文报道了在隔声室和不同声环境下对３０名１８～４０岁健康教职工和学生（男∶女＝１∶１）听阈测试。结果提示：声环境强度与听阈升高值呈线性关系。通过回归方程可计算不同声环境下各频率听阈测试校正值。
0 healthy adults from 18 to 40 years old (male vs.female is 1∶1)were tested by audiometer in the sound attenuated room and sound environment separately.The results showed that with the increase in environmental noise levels, the auditory threshold rised,the linear relations between the noise levels and rised values of the auditory thresholds determined by various frequencies were also found and some linear regression equations were given ,by which the approximate value of workers'auditory threshold could be acquired in the field without sound attenuated room.
