作者应用500Hz 短纯音对32名足月新生儿和10名5～8岁的正常儿童研究40Hz 稳态反应(SSR)。新生儿和儿童的40Hz SSR 阈值分别是50和30dBnHL。P_1和 N_1波的潜伏期均随年龄增长而显著缩短,但振幅却明显增大,未观察到潜伏期和振幅有显著的性别差异。而且随着年龄的增长,40HzSSR 变得更加稳定,测试-重复测试的重复性改善,_1-N_1波的出现率也增加了。在3个月至6岁的小儿,由于 Pa-ABR 和Pb～Pa 的间期不同,被认为是40HzSSR 来源的
The authors applied a 500 Hz short pure tone study of 40 Hz steady-state response (SSR) to 32 full-term newborns and 10 normal children aged 5 to 8 years. The 40 Hz SSR thresholds for newborns and children are 50 and 30 dBnHL, respectively. The latency of P_1 and N_1 waves decreased significantly with age, but the amplitudes increased significantly. No significant gender differences in latency and amplitude were observed. And with age, the 40 HzSSR became more stable, the repeatability of the test - repeated tests improved, and the incidence of _1-N_1 waves also increased. In children between 3 months and 6 years of age, 40-SSR-derived sources are considered due to the difference in Pa-ABR and Pb-Pa intervals
