Abstract: A home appliance, a home appliance system, and a controlling method thereof are disclosed. The home appliance includes an input interface, a communication interface, a processor, and a motor, wherein the processor is configured to receive input of an instruction regarding whether to activate a noise control mode from a user through the input interface, receive notification information including at least one of a received call or a received message from a terminal device interlocked with the home appliance through the communication interface, and based on the noise control mode being in an inactivated state, ignore the notification information and maintain the driving speed of the motor.

Abstract: Provided is an electronic device. The electronic device includes a motor, a memory configured to store at least one of first frequency information associated with a sound that is generated when the motor is driven or second frequency information associated with a surrounding environment of the electronic device, and a processor configured to control the motor to be driven by avoiding a driving speed corresponding to the frequency information stored in the memory.

Abstract: Disclosed herein is a range hood having improved sound characteristics by improving a structure thereof. The range hood includes a case including an inlet through which air is introduced, and a fan module arranged inside the case to suck air through the inlet. The fan module includes a fan configured to move air by rotating, a motor configured to supply a driving force to rotate the fan, a fan frame provided to accommodate the fan and the motor therein, the fan frame including a fan inlet and a fan outlet, and a sound generating member provided to generate a sound of a predetermined frequency band when in contact with the air discharged through the fan outlet.

Abstract: A home appliance including a first microphone that is disposed on a surface of a housing, a second microphone that is disposed on an inside of the housing, and a processor configured to perform signal processing for first voice data that is acquired from the first microphone, and perform voice recognition using the signal-processed first voice data. The processor is further configured to generate noise data using second voice data that is acquired from the second microphone and perform signal processing for the first voice data using the generated noise data.

Abstract: A home appliance is provided. The home appliance includes a motor configured to execute a predetermined function of the home appliance, and a processor configured to determine an upper limit of noise of the home appliance based on ambient noise information of the home appliance and control a driving speed of the motor to have magnitude of noise of the home appliance equal to or less than the upper limit of the noise.

Abstract: A home appliance including a communication device configured to communicate with another home appliance, a microphone configured to receive a voice from a user, and a processor configured to perform signal processing on first voice data obtained from the microphone and perform voice recognition using the signal-processed first voice data. Wherein the processor generates noise data using second voice data received from the other home appliance and performs the signal processing on the first voice data using the generated noise data.
