| Research Abstract |
I carried out frequency analysis for a deglutition sound to occur in the case of deglutition. The condition let you swallow cold water based on technique of MWST used many as screening of the deglutition optionally. I identified a deglutition sound at the time of the pharynx exercise from a deglutition sound and a screen of Video Capture which I described the pharynx in a supersonic wave video diagnosis device and identified an exercise range, and were busy in Powerlab. I calculated mean frequency using fast Fourier transform for a deglutition sound. It was 41.2+-5.2Hz, and the person of aspiration recognized the characteristic indicating a low band in 15.2+-3.2Hz, the normal people in the people of aspiration. As for the aspiration due to the cerebrovascular disorder, 11.8+-4.7Hz and disease properties were observed by 24.2+-2.8Hz, the spinocerebellar degeneration in that.
