A method of removing noise and an electronic device thereof are provided. The electronic device includes a speaker, a first sensor configured to output a first signal by obtaining noise around the electronic device, a second sensor configured to output a second signal by detecting vibrations around the electronic device, and a controller configured to determine whether the second signal satisfies a condition of not exceeding a certain threshold value, and output an acoustic signal to be output through the speaker based on the first signal according to a result of the determination.

Disclosed are a self-adaptive adjustment method of active noise cancellation (ANC) parameter, a device and a computer-readable storage medium. The method includes: obtaining frequency points of noise reduction headphone with energy loss and energy loss values of each frequency point, and determining a quantity of the frequency points with the energy loss values are greater than a first energy loss threshold; determining whether a sum of the energy loss values is greater than a second energy loss threshold, and determining whether the quantity of frequency points is greater than a preset frequency point quantity threshold.

A system and method for arranging sound zones in a room including a listener's position and a speaker's position with a multiplicity of loudspeakers disposed in the room and a multiplicity of microphones disposed in the room. The method includes establishing, in connection with the multiplicity of loudspeakers, a first sound zone around the listener's position and a second sound zone around the speaker's position, and determining, in connection with the multiplicity of microphones, parameters of sound conditions present in the first sound zone. The method further includes generating in the first sound zone, in connection with the multiplicity of loudspeakers, and based on the determined sound conditions in the first sound zone, speech masking sound that is configured to reduce common speech intelligibility in the second sound zone.
