频率（DELTA-F）和强度（DELTA-I）差异阈值直接比较蒙古沙鼠（长爪沙鼠），旧大陆非洲猴（Cercopithecus mitis，Cercocebus albigena），和人类。方法采用重复的背景AX辨别程序，并对动物进行阳性（食物）强化。对于DELTA-I，物种之间存在微小的数量差异。在1 kHz、70 dB SPL下，沙土鼠的DL平均值为2.82 dB，猴子为2.29 dB，人类为0.75 dB。对于DELTA-F，物种之间存在较大差异。在1 kHz、60 dB SPL下，沙鼠的频率DL最高，平均为108 Hz。猴子的DL较低，平均为32.6 Hz，与最近报道的其他旧世界猴子的DL相似（Prosen et al.，1990年）。人类的DL，平均2.27赫兹，明显低于猴子或沙鼠。这些结果表明，动物提供了比DELTA-F更好的人类DELTA-I模型。
Frequency (DELTA-F) and intensity (DELTA-I) difference limens were directly compared in Mongolian gerbils (Meriones unguiculatus), Old World African Monkeys (Cercopithecus mitis, Cercocebus albigena), and humans. Methods employed a repeating, background AX discrimination procedure, and positive (food) reinforcement for animals. For DELTA-I, there were small quantitative differences between the species. At 1 kHz, 70 dB SPL, DLs averaged 2.82 dB for gerbils, 2.29 dB for monkeys, and 0.75 dB for humans. For DELTA-F, there were larger differences between the species. At 1 kHz, 60 dB SPL, frequency DLs were highest for gerbils, averaging 108 Hz. DLs were lower for monkeys, averaging 32.6 Hz, similar to recently reported DLs for other Old World monkeys (Prosen et al., 1990). Human DLs, averaging 2.27 Hz, were markedly lower than those of either monkeys or gerbils. These results suggest that animals provide better models of human DELTA-I than DELTA-F.
