Click polarity inversion effects upon the human brainstem auditory evoked potential.

Parameters of the brainstem auditory evoked potentials (BAEPs) to high-intensity clicks of initial rarefaction (R) and condensation (C) phases differed. The amplitudes of Waves I, II and IV were greater with R clicks, while that of Wave V was greater with C clicks. The peak-latencies of Waves I and VI were shorter with R clicks and those of the remaining components tend to shorten with C clicks. At low stimulus intensities the preserved BAEP components (Waves III, V and VI) did not change noticeably with click phase inversion.

Frequency composition of brain-stem auditory evoked potentials.

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).
