许多动物使用声学通信作为一种手段，将重要的生物信息，如它们的位置，发送给潜在的接收者。然而，众所周知，人为噪声会影响某些物种产生或接收信号的能力，这可能会影响它们的繁殖成功。在这项研究中，我们研究了人为噪声对野外蟋蟀寻找配偶行为的影响。为了实现这一点，在不同的声学条件下，对雌性田野蟋蟀进行了趋声试验，并评估了它们检测和移动到同种雄性叫声的能力。交通噪音的存在降低了雌性接近雄性呼叫的可能性，也减少了雌性在做出决定之前处理呼叫刺激的时间。然而，白噪声的存在并没有降低接近呼叫者的可能性，这表明人为噪声的平均幅度单独在这场冲突中并不重要，但刺激或其他特征的频率和波动可能是重要的。这项研究支持这样一种假设，即人为噪声确实影响了声伴侣位置信号的可检测性，从而扰乱了配偶寻找行为。
Many animals use acoustic communication as a means of sending important biological information, such as their location, to potential receivers. However, anthropogenic noise is known to affect the ability of some species to either produce or receive signals, which may influence their reproductive success. In this study, we investigate the effect of anthropogenic noise on the mate-searching behaviors of the field cricket Gryllus bimaculatus. To accomplish this, phonotaxis trials were conducted with female field crickets under different acoustic conditions, and their ability to detect and move towards conspecific male calls was assessed. The presence of traffic noise reduced the likelihood that the female would approach the male calls and also reduced the time that the female spent attending to the calling stimulus before making her decision. However, the presence of white noise did not reduce the likelihood of approaching the calling speaker, indicating that the average amplitude of anthropogenic noise is, alone, not important in this conflict, but frequency and fluctuations in the stimulus or other characteristics might be. This study supports the hypothesis that anthropogenic noise does indeed influence the detectability of acoustic mate location signals, thus disrupting mate searching behavior.
