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: 400–1000 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).
