The invention belongs to the technical field of audio processing, and discloses an earphone sidetone adjusting method, an earphone sidetone adjusting device and an earphone. The earphone sidetone adjusting method comprises the steps of: when a pre-set condition is detected, obtaining the average power of audio signals acquired by a first microphone of the earphone and the average power of audio signals acquired by a second microphone of the earphone within a first predetermined time; comparing the average power of the audio signals acquired by the first microphone with the average power of theaudio signals acquired by the second microphone, so that the difference degree of the two is obtained; according to the difference degree of the average power of the audio signals acquired by the first microphone and the average power of the audio signals acquired by the second microphone, determining a step length value to be adjusted; and, according to the step length value, determining the gain of sidetone, and adjusting the sidetone of the earphone according to the gain. By means of the method, the sidetone of the earphone can be adjusted in real time; and thus, a relatively real sidetoneeffect can be realized.
Description
technical field [0001] The invention belongs to the technical field of audio processing, and discloses an adjustment method, an adjustment device and an earphone for side tone of an earphone. Background technique [0002] Sidetone usually refers to that in the headset, after the sending signal is processed, part of it is fed back to the part of the signal that receives the phone itself. If a headset is used for a call, the original voice is converted into an electrical signal by the microphone, and then transmitted to the other party through the communication line, and then transmitted back to the receiver of the party, so that the speaker can hear his own voice, which is side tone . [0003] Sidetone plays a very important role in improving the authenticity of speech. However, at present, fixed gain is used to adjust sidetone, but environmental changes or different wearing habits will affect the effect of sidetone. Contents of the invention [0004] In view of this, th...
