    摘要： An apparatus and method for wireless communication using an acoustic signal in a system including a first device including a loudspeaker and a second device including a microphone. The first device generates wireless communication information, converts the wireless communication information to an acoustic signal, and transmits the acoustic signal to the second device using the loudspeaker. The second device receives the acoustic signal using the microphone, extracts the wireless communication information from the acoustic signal, generates an acknowledgment signal according to the extracted wireless communication information, and transmits the acknowledgment signal to the first device on a wireless communication channel.

    摘要： An acoustic communication method and device are provided that filter an audio signal to attenuate a high frequency section of the audio signal. A residual signal is generated that corresponds to a difference between the audio signal and the filtered signal. A psychoacoustic mask is generated for the audio signal based on a predetermined psychoacoustic model. A psychoacoustic spectrum mask is generated by combining the residual signal with the psychoacoustic mask, an acoustic communication signal is generating by modulating digital data according to the acoustic signal spectrum mask, the acoustic communication signal is combined with the filtered signal, and radiating, by a speaker, the combined acoustic communication signal and the filtered signal in a form of sound waves.
