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.

Communication device and output sidetone adjustment method thereof

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&#x2264;|X&#x2212;Y|&#x2264;100; outputting the right channel second sound signal and the left channel second sound signal.

Sound adjustment method and sound adjustment device

A method for eliminating sound is disclosed. The method is applied to an electronic device capable of connecting with a sound playback device and includes a microphone. The method includes the following steps of: receiving a first input sound via the microphone to acquire a first input sound signal; recording the first input sound signal and transmitting the first input sound signal to the sound playback device; receiving a second input sound from the sound playback device to acquire a second input sound signal, wherein the second input sound is generated by the sound playback device according to the first input sound signal; determining a difference in generation times between the first input sound signal and the second input sound signal; and filtering the second input sound signal according to the difference in generation times and the first input sound signal.

Method for eliminating sound and electronic device performing the same

A sound playback device and a method for masking interference sound through a noise masking signal thereof are disclosed. The method comprises the steps of: playing an audio signal as a noise masking signal; receiving an ambient sound; analyzing whether the ambient sound has an interference sound in N different frequency bands; if so, finding at least one interference sound frequency band and a time period, and the interference sound conforms to the condition that an instant sound entropy value is greater than a dynamic sound average entropy value, wherein the instant sound entropy value is the calculated sound entropy value in a current sampling time; the dynamic sound average entropy value is an average entropy value of the sum of the previous instant sound entropy values; and increasing an energy of the noise masking signal in the interference sound frequency band and the time period.
