Abstract
A method and a device for information processing are provided. A plurality of sound signals are collected via a plurality of microphones. Next, a combined sound signal for each of at least one pair of the plurality of sound signals is generated by processing circuitry of the information processing device. Each combined sound signal is a combination of a respective pair of the plurality of sound signals. Further, an amplitude difference between the sound signals of each of the at least one pair of the plurality of sound signals is calculated by the processing circuitry. The amplitude difference between the sound signals of each of the at least one pair of the plurality of sound signals is compared with a preset threshold value. A notification message is accordingly generated when the amplitude difference between the sound signals of one or more of the at least one pair of the plurality of sound signals is greater than or equal to the preset threshold value based on the comparison. Subsequently, the notification message is output by the processing circuitry for presentation to a user.
