Abstract: | This paper presents psychological and physical experiments carried out by using a vibrometer as an acoustical calibration apparatus. This study has shown the relationship between the vibratory sensibility and the electric signal generated in a living body. The threshold curve for square wave vibration is lower by 12.3 dB than that for sine wave vibration near 30 Hz. The stimulus level is taken as the horizontal axis, and potential variation and strengh evaluation are plotted on the vertical axis, the former has a nearly rectiliner relation with the latter. |
