Abstract: A sound-receiving device includes a housing, a connecting cavity, a sound-receiving assembly, and a signal processing circuit. An outer surface of the housing is provided with a first sound-receiving hole and a second sound-receiving hole. The connecting cavity is provided in an internal space of the housing. The connecting cavity includes a connecting channel. A first hole and a second hole are respectively provided at two ends of the connecting channel. The first hole is connected to the first sound-receiving hole, and the second hole is connected to the second sound-receiving hole. The sound-receiving assembly includes a first sound-receiving diaphragm and a second sound-receiving diaphragm. The sound-receiving assembly is disposed between the first hole and the first sound-receiving hole. The signal processing circuit is electrically connected to the sound-receiving assembly. The signal processing circuit generates an output result according to the first sound and the second sound.

Abstract: An audio processing method includes the following steps: receiving audio information; capturing a square wave signal, a white signal, and a speech signal of the audio information; calculating a loudness value of the audio information; calculating a first sound quality value and a second sound quality value of the audio information by using the square wave signal, the white signal, and the speech signal of the audio information; calculating a sound quality level of the audio information by using a first calculation formula, the first calculation formula being the loudness value*[1+(B*the first sound quality value+C*the second sound quality value)], where B and C are respectively values greater than 0 and less than 0.1; and displaying a value of the sound quality level of the audio information.
