In order to determine unambiguously the bearing of a sound source, a fish must be able to resolve acoustic pressure and the components of the acoustic displacement vector from the signals detected by the otolithic organs. A new hypothesis for the processing of acoustical information by bony fish is presented. It is demonstrated that much of the processing required to do this may be implicit in the structure of the ear and its associated neural innervation. Possible algorithms are presented that the central nervous system might use to further process the derived information to localize a sound source and discriminate frequency and range. The hypothesis is shown to be consistent with much of what is known of the morphology and physiology of the auditory system of bony fishes.
为了明确地确定声源的方位，鱼类必须能够从耳石器官检测到的信号中分辨出声压和声位移矢量的各个分量。本文提出了一种关于硬骨鱼声学信息处理的新假说。结果表明，完成此项任务所需的大部分处理过程可能隐含在耳朵及其相关神经支配的结构中。文中还提出了一些可能的算法，中枢神经系统可能会利用这些算法进一步处理所获得的信息，以定位声源并辨别频率和距离。该假说与目前已知的硬骨鱼听觉系统的形态学和生理学的许多方面是一致的。
