Female phonotaxis in two-choice trials

Females given the possibility to approach either the left or right speaker simultaneously broadcasting different song models. Different chirp periods (CP) were presented simultaneously from different directions. Furthermore, identical song models were presented with a time lag of 70 ms and 140 ms. Data are summarized in figure 7本实验允许雌性个体趋近分别同步播放不同鸣声模型（song models）的左侧与右侧扬声器。实验中，不同啭鸣周期（chirp periods, CP）从不同方向同步呈现。此外，还以70毫秒与140毫秒的时间差播放相同的鸣声模型。相关数据已在图7中汇总。
