Abstract:
A device for sound wave communication, including: a hardware correction table for setting a correction frequency band; a sound wave transmission unit for generating data frequencies at a predetermined base decibel level, generating separate reception filter frequencies at the base decibel level for receiving data carried by a sound wave transmitted from the nearest location when sound waves are received, and generating the correction reference frequency at the base decibel level for correcting hardware transmission; and a sound wave reception unit for receiving a sound wave signal transmitted from the sound wave transmission unit, extracting decibel levels at each of the data frequencies to form an array of decibel levels, correcting the array by shifting the array by a correction value extracted using the hardware correction table, and reconstructing data.
