DEVICE AND METHOD FOR ACOUSTIC COMMUNICATION |
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. |
