Abstract: A communication device and an output sidetone adjustment method thereof are disclosed. The method includes the steps of: receiving a far-end sound; receiving a near-end sound to form a sidetone and obtaining an average input volume of the near-end sound; detecting ambient noise of the near-end sound; analyzing an average noise volume and a noise frequency band of the ambient noise to determine whether the average noise volume of the ambient noise is higher than the average input volume; if yes, adjusting the volume of the sidetone in a specific frequency band by increasing it by a first gain value to form an adjusted sidetone, wherein the specific frequency band and the noise frequency band of the ambient noise belong to the same frequency band or different frequency bands; and outputting the adjusted sidetone and the far-end sound.

Abstract: A sound adjustment method is disclosed. The sound adjustment method includes the following the steps: receiving a sound adjustment command; receiving a right channel sound signal and a left channel sound signal; selecting a corresponding adjustment mode according to the sound adjustment command and processing the right channel sound signal and the left channel sound signal based on the adjustment mode to generate a right channel first sound signal and a left channel first sound signal, wherein different adjustment modes have different intensity adjustment levels; shifting the frequency of the right channel first sound signal by X Hz to generate a right channel second sound signal and shifting the frequency of the left channel first sound signal by Y Hz to generate a left channel second sound signal, wherein 0.5≤|X−Y|≤100; outputting the right channel second sound signal and the left channel second sound signal.
