Abstract

Acoustic signals coming from the human head during mental activity are experimentally studied. Acoustic signals that differ from the signals during relaxation are revealed. Calculation of the multiplication table in the mind is used as mental activity. It is shown that the differences are due to a variation in the breathing pattern. It is also shown that the most informative signals related to respiration are observed from the crown region (at a point close to Cz used in encephalography) and the signals related to pulse activity are observed from the temple region (at point T3).

Keywords
