| The paper summarises the results of experiments carried out to investigate the effect of a narrow-band noise in the range 4-8 Hz and of the acoustic pressure SPL = 110 dB(HP) on the alpha waves in the EEG signal. The test group included 23 males aged 21-33. It is found out that white noise in the infrasound range 4-8Hz leads to changes of amplitudes of the spectral power density of alpha waves. The tests reveal a statistically significant reduction of the alpha wave amplitude during the infrasound exposure and an amplitude increase when the exposure is over. |
