In a standing wave tank responses of fish to sound stimuli used to investigate the hearing capacity of fish may perhaps be affected by unintended stimulation of the lateral line. Uniform oscillatory water flow patterns do not stimulate the lateral line. Departures from uniformity were derived from measurements to acoustic pressure and particle velocity at 5-cm spacings around the center in our standing wave tank containing six transducers suspended along three axes that are perpendicular to one another. These measurements are compared with the results of a model in which negligible influence of the tank wall and an incompressible water column in the tank are assumed. Deviations of computed values from measured values of sound pressure and the principal velocity components are less than 5 dB. The model underestimates velocity components perpendicular to the principal component. However, the model does appear a reliable aid for estimating the spatial function of sound pressure and velocity from the values of p and v measured at the tank center. Upper limits for the relative velocities between the fish body and the water can only approach threshold values for the lateral line stimulation under worst conditions (i.e., a velocity node at the tank center) in this setup.
在驻波水槽中，用于研究鱼类听力能力的鱼类对声音刺激的反应可能会受到侧线意外刺激的影响。均匀的振荡水流模式不会刺激侧线。在我们的驻波水槽中，沿着相互垂直的三个轴悬挂着六个换能器，通过在水槽中心周围以5厘米的间距测量声压和粒子速度，得出了与均匀性的偏差。将这些测量结果与一个模型的结果进行比较，该模型假设水槽壁和水槽中不可压缩水柱的影响可忽略不计。声压和主要速度分量的计算值与测量值的偏差小于5分贝。该模型低估了垂直于主要分量的速度分量。然而，该模型似乎确实是一种可靠的辅助工具，可根据在水槽中心测量的p和v值来估计声压和速度的空间函数。在这种设置下，鱼体与水之间的相对速度上限仅在最坏条件下（即水槽中心的速度节点）接近侧线刺激的阈值。
