Mechanical tuning curves were recorded at several radial locations on the Reissner's membrane, over a wide range of frequencies, and sound pressure levels. The position coordinates of each location were also recorded. The shape of the tuning curves changed dramatically with the radial location. Near the outer edge of the cochlea the response was broadly tuned, with a maxima near 300 Hz, while near the inner edge the response showed at least three maxima and minima. Responses were also measured at the reticular lamina. The shapes of the frequency responses at the Reissner's membrane are quite different from those measured at the reticular lamina below it.
在广泛的频率和声压水平范围内，在瑞氏膜的几个径向位置记录了机械调谐曲线。还记录了每个位置的坐标。调谐曲线的形状随径向位置显著变化。在耳蜗外边缘附近，响应调谐较宽，在300Hz附近有一个最大值，而在内边缘附近，响应至少有三个最大值和最小值。还在网状板处测量了响应。瑞氏膜处的频率响应形状与下方网状板处测量的形状有很大不同。
