The invention relates to a sound control apparatus of a vehicle and a control method thereof. A sound control apparatus installed in a vehicle and a control method include measuring a driving signal input to a speaker, in which the driving signal is generated in response to an input signal including at least one of a noise control signal and an audio signal, a state of a voice coil of the speaker including at least one of a displacement and a temperature of the voice coil is estimated based on the driving signal and a model of the speaker, and the input signal is adjusted based on the state of the voice coil. 本公开涉及车辆的声音控制装置及其控制方法。一种安装在车辆中的声音控制装置和控制方法，包括测量输入至扬声器的驱动信号，其中，响应于包括噪声控制信号和音频信号中的至少一个的输入信号来生成驱动信号，基于驱动信号和扬声器的模型来估计包括音圈的位移和温度中的至少一个的扬声器的音圈的状态，并且基于音圈的状态来调整输入信号。
