Abstract: The present disclosure provides a computer-implemented method for sound masking. The method includes identifying one class among a plurality of classes based on frequency characteristics of a voice of a first occupant in a vehicle, obtaining reference voice data corresponding to the identified class, generating a personalized masking sound for the first occupant by synthesizing the reference voice data with white noise, and controlling an output of the personalized masking sound.

Abstract: A method for controlling a sound control device in a vehicle includes obtaining at least one of a reference signal obtained from a sensor or an error signal obtained from a sound signal of a microphone, estimating a road surface environment corresponding to a road surface on which the vehicle is traveling based on the reference signal, and adjusting a gain for generating a noise control signal having a magnitude within a preset range based on at least one of the road surface environment or the error signal.

Abstract: A mobile terminal and controlling method thereof are disclosed, which facilitates a terminal to be used in further consideration of user's convenience. According to at least one of embodiments of the present invention, while a first function is being executed in a mobile terminal, if a second function different from the first function is executed, a first function icon having execution progress status information of the first function at a timing point of stopping the execution of the first function can be generated. If the first function is re-executed by selecting the first function icon later, it is advantageous in that the first function can be executed in a manner of being continuous with an execution progress status at the execution stop timing point.

Abstract: A mobile terminal and controlling method thereof are disclosed, by which a terminal user is facilitated to use a specific function of a mobile terminal in a locked state to prevent an incorrect touch input to a touchscreen provided to the mobile terminal. The present invention includes entering a terminal locked state, displaying a standby image on a touchscreen by image blurring, releasing the locked state if a prescribed touch gesture is performed on the touchscreen, and displaying the standby image by image deblurring.
