摘　　要：目的通过扬声器给声，记录正常听力的成人和婴儿的听性稳态反应结果，探讨其应用价值。方法采用AUDIX测试系统，扬声器给声，分别记录睡眠状态下听力正常的成人（18例，年龄20～22岁，平均21．6岁）和婴儿（11例，月龄5～11个月，平均9．5月）的听性稳态反应阈值。结果正常成人组0．5、1、2、4kHz4个频率的反应阈值分别为73．67±3．12、69．72±4．88、68．74±4．45、71．32±3．35dBSPL；正常婴儿组4个频率的反应阈值分别为77．65±2．36、71．12±3．24、71．80±3．28、72．78±4．12dBSPL。两组各个对应频率的测试结果差异无统计学意义（P〉0．05）。结论成人或者婴儿均可以通过扬声器给声来记录听性稳态反应。Objective To recorde the auditory steady--state responses of normal hearing peoples and young babies in sound field and to discuss the value. Methods Using loud speaker stimuli, a group of normal hearing adutls and infants were tested. The response thresholds of auditory steady--state responses were recorded. Results For normal adults,the thresholds of ASSR at four frequencies were 73.67±3. 12,69.72±4.88,68. 74±4. 345, 71. 32±3.35 dB SPI. respectively, while for normal infacts, these results were 77.65±2.36,71. 12±3.24,71.80± 3.28,72.7±84.12 dB SPL. The difference of the ASSR thresholds between normal adults and infants has no statislics significance. Oonclusion ASSR could be recorded for normal adults and infants in sound field.
