对雄性蟋蟀（Gryllus bimaculatus）的实地研究表明，雄性蟋蟀会形成叫声聚集。在群体内，雄性似乎在它们的洞穴周围保持着一个专属的雌性吸引区；因此，鸣叫可以作为一种攻击性信号，向邻近的雄性发出保持距离的信号。呼唤的歌声随着距离而衰减。此外，由于低频成分的损失以及啁啾和脉冲之间的间隔由于混响而减少，呼叫随着距离的增加而降低。回放实验表明，可预测的叫声退化特性可能是一种寻找距离的机制，可以维持观察到的雄性间距。鸣叫的强度、啁啾和脉冲的重复率与雄性的体型呈正相关。虽然由于不可预测的衰减和不规则的幅度波动，呼叫强度参数中包含的信息可能被证明是不可靠的，但啁啾和脉冲的重复率不受距离退化的影响。在强度可控的回放实验中，雌性更倾向于听从体型较大的雄性的叫声。
Field studies of calling male field crickets,Gryllus bimaculatus, showed that males formed calling aggregations. Within aggregations males appeared to maintain an exclusive female-attraction zone about their burrows; calling song may thus serve as an aggressive signal to neighbouring males to maintain spacing. Calling song attenuates with distance. Furthermore, calls became degraded with distance by the loss of low frequency components and a reduction in the interval between chirps and pulses due to reverberation. Playback experiments suggested that the predictable degrading properties of the call may serve as a distance-finding mechanism maintaining observed male spacing. The intensity of calls and the repetition rate of chirps and pulses was positively correlated with male size. While information contained within the intensity parameter of calls may prove unreliable due to unpredictable attenuation and irregular amplitude fluctuations, the repetition rate of chirps and pulses was not affected by distance degradation. Playback experiments in which intensity was controlled suggested that females orientate preferentially to the calls of large males.
