 | | In this study, we played synthetic song that varies in pulse length and carrier frequency to individual females in the laboratory, both alone and in the presence of mute males. |
 | | The presence of mute males significantly increased their overall responsiveness, but the relative effectiveness of the songs did not change, eliminating male reaction to song as a possible confounding factor in the results. |
 | | Left is song from a real male, right are examples of synthetic songs used in playback experiments (top has a short pulse length and high carrier frequency, middle has medium pulse length and carrier frequency, bottom has long pulse length and low carrier frequency). |
