测定了4种动物的行为学听像图，1种家兔（Oryctolagus cuniculus）和3种野生啮齿动物（Sigmodon hispidus棉鼠、家鼠、小家鼠和袋鼠鼠）。4种动物的听力差异较大，低频听力范围在50 ~ 2300hz（袋鼠大鼠）的5个半音阶以上，高频听力范围在49 ~ 90khz（家兔）的范围内。将每个听力图的特征与同一目、同一群的其他动物的听力图进行比较，为2种关系的有效性提供证据。在大多数陆地哺乳动物中，间隔距离与高频听力能力呈强烈的负相关，而良好的高频听力与良好的低频听力显然是不相容的。棉鼠和野生小鼠具有识别频率的能力，即使是在非常高的频率。他们感知高频和低频声音的方式可能没有区别。袋鼠鼠在定位简短声音的能力上并不罕见。显然，这些动物在获得不寻常的低频灵敏度时并没有损害这种能力。
Behavioral audiograms were determined for 4 spp. of Glires: 1 lagomorph (domestic rabbit, Oryctolagus cuniculus) and 3 feral rodents (cotton rat, Sigmodon hispidus; house mouse, Mus musculus; and kangaroo rat, Dipodomys merriami). Considerable variation in hearing ability was found among the 4 species with low-frequency hearing limits ranging over 5 1/2 octaves from 50 (kangaroo rat) to 2300 Hz (feral mouse) and high-frequency hearing limits ranging from 49 (rabbit) to 90 kHz (feral mouse). The characteristics of each audiogram were compared with the audiograms of other animals of the same Order, Cohort and providing evidence for the validity of 2 relationships. Interuteral distance was strongly and inversely correlated with high-frequency hearing ability and good high-frequency hearing was apparently incompatible with good low-frequency hearing in most, if not all, land mammals. cotton rats and feral mice possessed the ability to perform frequency discriminations even at very high frequencies. There was probably no difference in the way in which they perceive high- and low-frequency sounds. Kangaroo rats were not unusual in their ability to localize brief sounds. These animals apparently have not compromised this ability in their acquisition of their unusual low-frequency sensitivity.
