As an adequate physiological method can be non-linear stochastic RR-intervals (NSC), which makes it possible to estimate the stochastic features of system processes ensure the perception of information, including musical works. This method was used in an experimental model of structure while listening to music they different directions. Every musical direction (classical, spiritual, rock and house music) was listening for 5 minutes in a closed dynamic headphones Philips (power 500 MW with a frequency range of
15-22000 Hz) and was accompanied by a simultaneous rr-interval registration. Cardiointervals were processed on-line and presented in a digital form (Software package by Uritskii V.M., Muzalevskya N.I.).
Mean values of RR-intervals (inter-beat intervals), mean square deviation of cardiointervals (MSD RR – estimation of rhythm variability), LF/HF ratio (measure of the activity of the sympathoadrenal and

126 parasympathetic centers of the autonomic nervous system), So - spectral power at the lowest frequency of the power spectrum obtained by fast Fourier transform were recorded. So is associated with an activation of cortical fields. Fractal ß index is an indicator of the degree of system organization of the cortical control of the heart rhythm. The lower the value of the fractal index is, the higher chaotization of homeostasis in higher levels of the heart rhythm control system is. The optimization of the cardiac rhythm control system is observed in the range of the fractal index from -0.8 to -1.0.
Registration-r-interval variation was carried out 5 times in 5 minutes: first registration is operationally rest, four next-while listening to the abovementioned musical works. Analysis of the frequency of the spectral characteristics of music for listening requirements, using SteinbergWaveLab and Adobeaudition 0.6 5.5.
Music listening requirements: classical work Symphony No. 40 by W.a. Mozart, part 1; hard rock

A total of 206 subjects were observed: 50 boys and 54 girls aged 7-8 years; 48 boys and 54 girls aged 14-16 years. All subjects had 1 and 2 group health.
We have founded that both children 7-8 years, and teenagers 14-16 years the perception of music of different areas was accompanied by changes only by the cortical functional activity mechanisms of regulation, i.e. parameters such as So and β, links with age of subjects, psychological characteristics, musical preferences, as well as music education show failed.
Frequency spectral analysis of pieces of music, as the stimulating signal revealed a fundamental difference in their spectra and perceived volume. A comparative analysis of the dynamic performance requirements for listening to music showed the similarity between rock and house music such as spectral power and the perceived loudness of the sound; with the highest values of this parameters in combination with the highest values perceived volume accounted for low and high frequency ranges. The spiritual chant is characterized by minimum mean square amplitudes of virtually all frequency ranges, combined with the highest values of the perceived volume of medium-and high-frequency ranges. The distinctive feature of the classical musical works by W.a. Mozart turned similarity values, as the mean square amplitudes and perceived volume in all four frequency bands.
All investigated the dynamic characteristics of tapped music have founded correlations exclusively with functional activity and quality of integration of functional linkages at the level of cortical mechanisms of regulation, but not with values r-r-interval measurement and variability of pulse. Optimization of functional activity of cortical mechanisms of regulation was determined by the frequency spectral characteristics requirements for listening to music, but the young men and boys-upon presentation of rock and house music, girls-music by Mozart and spiritual chants.

Одной из актуальных в современной науке проблем является исследование психофизиологических особенностей восприятия музыки, а также ее воздействия на системные психофизиологические процессы обеспечения деятельности и поведения человека. Принято считать, что музыка является неслучайным продуктом эволюции человека как биологического вида. Представляя собой, по сути своей, отражение процессов, протекающих как в головном мозги в организме в целом, таки во внешней среде музыка обладает способностью оказывать в разной степени адекватное и эффективное воздействие на текущее функциональное состояние, поведение и деятельность человека. Практически неисследованными являются вопросы дифференцированного восприятия музыки мужчинами и женщинами, не изучены психофизиологические механизмы этого дифференцированного восприятия музыки различных направлений. С учетом того, что подавляющее большинство композиторов – мужчины, данное направление экспериментальной работы представляет особый интерес. Известно, что музыка как сложная нелинейная система акустической природы может быть подвергнута анализу и построению спектра мощности. В связи с этим отдельного внимания заслуживают и частотно-спектральные характеристики предъявляемой для прослушивания музыки и обнаружения ее связи с психофизиологическими особенностями восприятия.
