The WKB approximation was used in calculations of the pure-tone response of a two-dimensional inviscid model of the human cochlea and a three-dimensional inviscid model of the guinea pig cochlea. The common experimental procedure of opening the scala tympani was simulated. Basilar membrane displacement was unaffected at and beyond the peak, but was slightly lower pre-peak. The peak location shifted to a significant extent apically only when the fluid level in the scala tympani was lowered to less than 1/10 of normal depth.
WKB近似法被用于计算人类耳蜗的二维无粘模型和豚鼠耳蜗的三维无粘模型的纯音响应。模拟了打开鼓阶的常见实验过程。在峰值处及峰值之后,基底膜位移未受影响,但在峰值之前略低。仅当鼓阶中的液位降低到正常深度的1/10以下时,峰值位置才会在顶端显著移动。
