Abstract: PROBLEM TO BE SOLVED: To provide an acoustic signal transfer method by which multiple information items can be combined with limited acoustic channel band signals and transferred.SOLUTION: In a modulation processing part 55 of an AM modulation part 43, down sampling is performed on an acoustic signal of LFEch, AM modulation is executed by a carrier signal CS inputted from a carrier generation part 56, and a modulated signal is outputted to adders 51 and 52.

The carrier generation part 56 outputs a signal in a frequency band that is ordinarily hard to hear for human ears as the carrier signal CS. Thus, even if equipment at a transfer destination is non-adaptable to demodulation and reproduces added acoustic signals as they are, the acoustic signals can be heard as sounds with no sense of incompatibility.SELECTED DRAWING: Figure 3
