PROBLEM TO BE SOLVED: To provide a transmission method of an arbitrary signal using a sound hardly affecting the atmosphere (quality) of the original sound even if an arbitrary signal within an audible frequency range is added to the sound such as music or the like.SOLUTION: A separable sound having an essential portion (essential sound) b2 that subjectively contributes to recognition of one sound and an accompanying portion that incidentally contributes to recognition of one sound in a separable manner on a temporal axis are found from a plurality of sounds constituting the sound or inserted into the plurality of sounds constituting the sound. The accompanying portion of the separable sound to be found or to be inserted is changed to signal patterns b1-1 and b1-2 of the arbitrary signal, and the arbitrary signals b1-1 and b1-2 are transmitted by the changed sound. The accompanying portion means the sound or the like generated when oscillation energy is delivered to a resonator (resonant body). The essential portion means the sound or the like played by the resonator (resonant body) having received oscillation energy according to its own resonance (resonance) mode. |
