The Research of EEG Analysis Methods Based on Sounds of Different Frequency

摘要

In this study, we carry out a research of EEG analysis base on sounds of different frequency. Experiment schemes are designed to obtain the EEG data. Wavelet transform decomposes the EEGs into signals of different frequency. Modulus maximum is applied to detect the extrude spots and power spectrum is used to show the power distribution of EEG with frequency. Through studying, analyzing and comparing EEG data based on different frequency sounds, the characters of brain are drawn, the relationship between sound and brain is analyzed using research results. The results of the experiments are valuable to actual life, such as navigation for the blind based on different frequency sounds.
