Pups aged 1 to 10 days, of deaf and hearing mouse strains, were monitored with an ultrasound detector while submitted to standard conditions of cold, isolation, and retrieving. The number of detections varied with the age of the pups and with the type of treatment (as established previously) but not with the genotype of the pups. Thus, occurrence and changes with age in ultrasound emission do not seem to be greatly influenced by their effects upon adult behavior.
对1至10日龄的聋鼠和听力正常小鼠品系的幼崽，在使其处于寒冷、隔离和找回的标准条件下时，用超声波探测器进行监测。探测次数随幼崽年龄和处理类型（如先前确定的）而变化，但不随幼崽的基因型而变化。因此，超声波发射的出现及其随年龄的变化似乎并未受到其对成年行为影响的很大影响。
