Abstract
It has been demonstrated by digital filtration and power spectra analysis that main energies of different components of human brain-stem auditory evoked potentials are concentrated in the following frequency bands: 400--1 000 Hz for waves I and II, 100--900 Hz for wave III, and 100--500 Hz for waves IV--VI. The data obtained are compared with those published in Scand Audiol by Terkildsen et al. (1975) and Elberling (1976).
摘要
通过数字滤波和功率谱分析已证明，人脑脑干听觉诱发电位不同成分的主要能量集中在以下频段：波Ⅰ和波Ⅱ为400 - 1000Hz，波Ⅲ为100 - 900Hz，波Ⅳ至波Ⅵ为100 - 500Hz。将所获得的数据与Terkildsen等人（1975年）以及Elberling（1976年）发表在《斯堪的纳维亚听力学》上的数据进行了比较。
