我们测定了两只短尾果蝠 (Carollia perspicillata) 的听力图，它们是来自中美洲和南美洲的 18 克叶口蝙蝠。为了进行测试，我们使用了带有果汁奖励的条件抑制/避免程序。在 60 dB SPL 强度下，C perspicillata 的听觉范围从 5.2 kHz 延伸到 150 kHz，在 25 kHz 处显示出 0 dB 的最佳灵敏度，在 71 kHz 处显示出次要灵敏度区域。虽然 C. perspicillata 是食果类动物，因此不依赖声纳来探测和追踪昆虫，但其听力图与食虫蝙蝠相似；同样，没有迹象表明其低强度回声定位呼叫具有异常敏感性。将行为听力图与之前发布的听力生理估计值进行比较。 (C) 2003 Elsevier Science B.V. 保留所有权利。
We determined the audiograms of two short-tailed fruit bats (Carollia perspicillata), 18-g phyllostomids from Central and South America. For testing, we used a conditioned suppression/avoidance procedure with a fruit juice reward. At an intensity of 60 dB SPL, the hearing of C perspicillata extends from 5.2 to 150 kHz, showing a best sensitivity of 0 dB at 25 kHz and a secondary region of sensitivity at 71 kHz. Although C. perspicillata is frugivorous, and therefore does not rely on sonar for detecting and pursuing insects, its audiogram is similar to that of insectivorous bats; similarly, there is no suggestion of unusual sensitivity associated with its low-intensity echolocation calls. The behavioral audiogram is compared to previously published physiological estimates of hearing. (C) 2003 Elsevier Science B.V. All rights reserved.
