Abstract
A hearing aid device with functions of anti-noise and 3D sound recognition is disclosed. The hearing aid device comprises N microphones, at least one A/D converter, a modular electronic device, a D/A converter, and a loudspeaker. According to the present invention, the modular electronic device is configured for generating N second audio signals based on N first audio signals and a HRTF signal, and then summing up the N second audio signals to a reference signal. Moreover, the modular electronic device is further configured for generating a first output signal after applying an ANC process to the reference signal, converting the reference signal to a second output signal, and then generating an output signal based on the first output signal and the second output signal. Consequently, the loudspeaker broadcasts a sound according to the output signal.
