In previous studies, we measured swallowing sounds using acceleration sensors attached to the neck, and performed time-frequency analysis on the swallowing sounds obtained. We also quantitatively assessed swallowing function by finding the envelope of the swallowing sound signals via cubic spline interpolation and calculating a parameter, Swallowing Function Parameter (SFP), that indicates the subject's swallowing function. In this report, after examining methods for measuring swallowing sounds surely, we investigated the effects of water jelly at different temperatures on swallowing function. As a result, we came to be able to measure swallowing sounds surely in both men and women. In addition, from the results of the texture test and the measurement of the swallowing sound of the water jelly, it was found that the SFP value decreased most at 20°C.
