In this study, the general characteristics, and theories of cochlear concerning with hearing are examined. Also the digital method is studied in order to analyze with microcomputer on the model equation of basiliar membrane in the cochlear derived from 3-dimensional rectangular block model which is studied by Boer. The method is illustrated for the amplitude characteristics of basiliar momtrane wave velocity. The results obtained are as follows; 1. In the magnitude characteristics, the velocity gradually increases from the stapes, shows the maximum magnitude, and then rapidly decreases to the Helicotrema. 2. The characteristics of 3-dimensional model is located between 1-and 2- dimensional models in the velocity characteristics coefficients, magnitude characteristics, and the pattern of 2-dimensional model shoves the different features from the 1-dimensional and 3-dimensional rectangular block model. 3. In the 3-dimensional rectangular block model, the characteristics of the waveform and the maximum resonant point are same whether Z(X) is linear or nonlinear.
