Changing resonator geometry to boost sound power decouples size and song frequency in a small insect

摘要

Memorable feature of warm summer nights is the sound of scores of crickets singing all together. Male crickets put on this impressive auditory display to attract mates. Song provides an acoustic beacon that females can home in on. It also enables other sophisticated functions such as species recognition and the evaluation of mate fitness. Its frequency is generally accepted to be important for species recognition; nonetheless, there is subtle variation in the spectral quality of songs sung by males within a species.
