Abstract (in Japanese) (See Japanese page) 
(in English) We have analyzed the sound of bell crickets in anechoic chamber using 768kHz/32bit high resolution
recording system including inaudible sound range. The results show that the sound has a distinctive signal waveform
on a scale of about 50 ms. This entire waveform is composed by connecting those base units which is changing
the amplitude and time span. The high-resolution acoustic measurement was able to analyze the sound pressure
waveform of the bell cricket and its acoustic characteristics in the frequency domain with high precision. Based
on the results of this analysis, we examined the application to individual identification using the support vector
