本文提出了一种计算传输线耳蜗模型数值解的有效方法，并将其应用于Verhulst等人的模型，通过采用变步长数值方法求解描述该模型的常微分方程组，扩展了模型的稳定区域，并且通过采用自适应方案来考虑每个数值步长内的系统状态的变化。所提出的方法导致提高模拟的数值精度和大量的计算节省，导致采用TL模型比目前可能的更广泛的模拟。(C)2014年美国声学学会
This paper presents an efficient method to compute the numerical solutions of transmission-line (TL) cochlear models, and its application on the model of Verhulst et al. The stability region of the model is extended by adopting a variable step numerical method to solve the system of ordinary differential equations that describes it, and by adopting an adaptive scheme to take in account variations in the system status within each numerical step. The presented method leads to improve simulations numerical accuracy and large computational savings, leading to employ TL models for more extensive simulations than currently possible.
