摘要
An electroencephalogram measurement apparatus includes: an electroencephalogram measurement section for measuring an electroencephalogram of a user by using a plurality of electrodes; an electro-acoustic transducer for presenting an acoustic signal to the user, the electro-acoustic transducer being in a vicinity of at least one electrode among the plurality of electrodes while the electroencephalogram measurement section is worn by the user; an amplitude envelope extraction section for extracting an amplitude envelope of the acoustic signal presented by the electro-acoustic transducer; a frequency analysis section for applying a frequency analysis to the amplitude envelope extracted by the amplitude envelope extraction section; and a noise estimation section for estimating an electrical noise which is mixed at the at least one electrode by using a previously provided set of transform rules and the extracted amplitude envelope.
