PURPOSE: A sound wave communication system and a method thereof are provided to minimize errors for detecting information within a sound source of audio content due to masking effect. CONSTITUTION: A transmission unit(100) generates a modulation audio signal which amplitude size is controlled based on a masking threshold value. The transmission unit determines sound variation of the audio signal. The transmission unit re-controls amplitude of a signal band. A reception unit(200) receives an output audio signal. The reception unit outputs information data of the output audio signal. |
