Estimation of Frequency Differential Limen to Modulated Vibratory Stimuli

Abstract

The purpose of this research is to clarify characteristics of the frequency differential limen to modulated vibratory stimuli. In this study, each frequency differential limen to 15 kinds of standard stimuli is determined by psychophysical measurement. In the measurement, comparison stimuli were introduced in all four directions of the standard stimulus, and the approximation model is generated based on the measured frequency differential limen.
As a result, it was confirmed that the frequency differential limen increases with an increase in the frequency. In addition, the estimation of a frequency differential limen to an arbitrary standard stimulus in the frequency area was attempted for the approximation model.
