Summary: | A method for controlling a sound control apparatus in a vehicle includes: obtaining at least one of a reference signal obtained from a sensor and 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 travels based on the reference signal; and adjusting a gain for generating a noise control signal having an amplitude within a preset range based on at least one of the road environment or the error signal.
一种用于控制车辆中的声音控制装置的方法包括:获得从传感器获得的参考信号和从麦克风的声音信号获得的误差信号中的至少一个信号;基于参考信号估计与车辆在其上行驶的路面相对应的路面环境;以及基于路面环境或者误差信号中的至少一个来调整用于生成幅度在预设范围内的噪声控制信号的增益。 |
