A sound control device and a method for controlling the sound control device in a vehicle. The method comprises obtaining an error signal indicating residual noise in the vehicle, and an audio signal; calculating magnitudes of low frequency components of the error signal; adjusting magnitudes of low frequency components of the audio signal according to the magnitudes of the low frequency components of the error signal; and outputting the adjusted audio signal through a speaker.

Sound control device of vehicle and method for controlling the same

A sound control device mounted in a vehicle and control method thereof includes obtaining whether an audio function is ON or OFF, and determining a maximum limit value for a displacement of a speaker due to a noise control signal according to whether the audio function is ON or OFF.

Sound control device and control method thereof

A sound control device in a vehicle and control method thereof may include obtaining energy per unit time of an audio signal corresponding to a preset low frequency band, calculating an allowable reference value based on a difference between a magnitude of energy per unit time of the audio signal and a magnitude of a preset maximum allowable input of a speaker, monitoring whether a magnitude of energy per unit time of a noise control signal for eliminating noise in the vehicle exceeds the allowable reference value, and adjusting a magnitude of the noise control signal when the magnitude of energy per unit time of the noise control signal exceeds the allowable reference value.
