Comparative Analysis on the Sounds Acoustic Property of Gryllus bimaculatus

Abstract: The structure,power spectrum and temporal parameters of the calling sound,courting sound and wrestle sound (different sex ratio) of Gryllus bimaculatus were studied with acoustic analysis techniques of computer.The results show:1) Pulse length (PL),inter pulse interval (IPI),pulse number of each pulse group (PN),and sounds pulse are almost the same in the calling sound,courting sound and wrestle sound.These features show the species recognition of factor.Among them,IPI is the most important.2) Other features,such as rhythm,sound length,sou nd intermission have a close contact with the social and individual activity of Gryllus bimaculatus.From calling sound to courting sound,the syllable num bers of each rhythm is gradually increasing from one syllable,two syllables to many syllables.But sound intermission is decreasing.In the different sex rate,t he number of males clearly affects the sound feature.When male increase,the rhy thm and sound length increase,but sound intermission decrease.Different rate of female have no law.3) Power spectrum and temporal parameters of the sound has a corresponding relation.Various pulse energy of sounds,including calling sound,courting sound and wrestle sound assemble in one energy range.
