Analysis Of Alpha And Beta EEG Signal Pattern In Trypophobia Condition With Wavelet Method

A phobia is a human fear of things that are very trivial for people. One phobia, Trypophobia, is the fear of visual small holes. The effect of the trypophobia effect can we see its brain waves with a device called EEG or called Electroencephalograph, so we can understand who really improved Trypophobia or not. In this final project a system was developed to classify the condition of someone who is not afraid, and the condition of someone who is afraid of Trypophobia is based on alpha signal analysis and EEG beta. Artificial Neural Networks (ANN) are used for classifying conditions. For the extra features of the data Discrete Wavelete Transform (DWT) is used so that system performance can be improved and reduce the EEG dataset dimensions. The test results show that the best performance is obtained in beta signals which have the highest characteristic parameter accuracy are Maksimum, Standard Deviation and Variance with an accuracy value of 100%, with a calculation time of 0.027 and 0.037 seconds. While for alpha signals obtained with Variance and Interquartile Range parameters of 96.42% with a time of 0.03 and 0.032 seconds. Although the accuracy is the same, but the average is resolved based on the neurons, beta is higher than alpha, so it can told that beta signals more than sensitive to such as Trypophobia and AF7 channels good in catching EEG signals of Trypophobia stimulated condition.
