Aim of research. The analysis of the tones processing speed of at their bi- and monaural presentation by the parameters of latent periods of auricular cognitive evoked potentials in musician and non-musicians. Methods. The method of registration of cognitive evoked potentials of auricular modality was used. Results of research. Musicians have shorter latent periods of the components N2 and Р3 of cognitive evoked potentials at bi- and monaural presentation of tones. At left-side presentation of tones there were not revealed any differences between musicians and non-musicians as to the latent periods N2, P3, N3. There were not revealed any differences between musicians and non-musicians as to the inter-peak interval N2-P3; the interval N2-N3 is longer in musicians in the right hemisphere at binaural presentation of tones. The amplitude of the component Р3 did not differ between groups. Conclusions. At binaural and right-side presentation of tones, musicians process them faster than non-musicians, because the process of stimulus recognition starts earlier in musicians. At the left-side presentation of tones, the differences in their processing speed in musician and non-musicians are not revealed
