We used this experimental setup to measure acoustic coupling and PRCs for male snowy tree crickets. The cricket was housed in a small cage inside a larger anechoic chamber or sound attenuating booth. A speaker broadcasted the stimulus and a microphone recorded both the cricket’s song and the output of the speaker. The microphone output was filtered and digitized to a computer using a 16-bit A/D converter (TDT). The microphone output also served as input into a Schmitt trigger that provided the trigger to the D/A converter that broadcasts the stimulus. The trigger and the D/A outputs were also digitized to provide precise timing of the experimental events.
