This research will investigate sound source localization by fishes to ascertain how fish integrate the various sound cues available to them to behave appropriately in complex acoustic environments. Evidence suggests that the capacity for sound source localization is common to mammals, amphibians, birds and reptiles, but surprisingly it is not known whether fishes locate sound sources in the same manner. Therefore, sound source localization by fishes remains an important topic in biology and in the hearing sciences. This study will test the major assumptions of several related theories, including the leading theory of sound source localization by fishes. The plainfin midshipman fish (Porichthys notatus), in which females locate males by sounds that the males produce, will be used as a general model to investigate how fishes localize underwater sound sources. Two hypotheses will be tested: 1) fish orient to the direction of acoustic particle motion to localize sound sources (a major assumption of several, related theories including the leading theory of sound source localization), and 2) both particle motion and sound pressure detection (via the swimbladder) are necessary for sound source localization, but neither alone is sufficient. As an integral part of this research program, both graduate and undergraduate students will receive training and mentoring. In addition, annual public lectures regarding this research will be presented at the University of California Bodega Marine Laboratory.

这项研究将调查鱼类的声音来源定位，以确定鱼如何整合可用的各种声音提示，以在复杂的声学环境中适当地表现。 有证据表明，声源定位的能力对于哺乳动物，两栖动物，鸟类和爬行动物是共同的，但令人惊讶的是，尚不清楚鱼类是否以相同的方式定位声源。 因此，鱼类的声音来源定位仍然是生物学和听力科学中的重要主题。 这项研究将测试几种相关理论的主要假设，包括鱼类的主要声音源定位理论。 Plainfin Midshipman Fish（Porichthys Notatus），其中女性通过雄性产生的声音定位男性，将用作研究鱼类如何定位水下水下声音来源的通用模型。 将测试两个假设：1）FISH向局部声源的声学粒子运动方向的方向（主要假设几种相关理论，包括声音源定位的主要理论），2）粒子运动和声音压力检测（通过游泳源）是声音源定位所必需的，但既足够了。 作为该研究计划不可或缺的一部分，研究生和本科生都将接受培训和指导。 此外，有关这项研究的年度公开演讲将在加利福尼亚大学bodega海洋实验室介绍。
