鸟类的声音是在各种噪音条件下产生的。因此，随着噪音条件的变化，改变信号的幅度可能对鸟类有益。我们通过记录雄性和雌性斑胸草雀（Taeniopygia guttata）的情况来测试这一点，因为它们受到不同级别的白噪声的影响。男女都会随着噪音水平的增加而增加发声的幅度水平。人类也获得了类似的结果（“伦巴第效应”）。研究结果根据鸟鸣声和诚实信号的“活跃空间”进行了讨论。 (C) 1998 年动物行为研究协会。
Bird vocalizations are produced under various noise conditions. It could therefore benefit birds to alter the amplitude of their signals as noise conditions change. We tested this by recording male and female zebra finches, Taeniopygia guttata, as they were subjected to various levels of white noise. Both sexes increased amplitude levels of vocalization in response to increased levels of noise. Similar results were obtained with humans (the 'Lombard effect'). The results are discussed in terms of the 'active space' of bird song and honest signalling. (C) 1998 The Association for the Study of Animal Behaviour.
