<p><P>PROBLEM TO BE SOLVED: To provide an audible sound, applied to a person to artificially induce Fmθand a method of artificially generating the audible sound. <P>SOLUTION: In this audible sound for inducing Fmθ, very low frequency as much as frequency of about 20 Hz or less is superimposed on the low frequency of an audible region. According to this generation method of audible sound for inducing Fmθ, the low frequency of the audible region is amplitude-modulated with very low frequency as much as frequency of about 20 Hz or less, and an electric signal including modulated wave formed by superimposing a very low frequency on the obtained low frequency is electroacoustic transduced. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
