The invention provides a noise reduction method and device, a vehicle and the like. Position information indicating the position of the head or ear of the user is acquired by a camera or the like. In accordance with the position information, the position of the speaker is controlled such that the speaker as an anti-noise source moves so as to approach the head or ear of the user, but there is a distance from the position of the head or ear, the distance being a target distance within a certain range. In this state, the loudspeaker emits anti-noise for noise reduction. As the loudspeaker emits anti-noise near the ear, a good noise reduction effect can be obtained.
本申请提供一种降噪方法、装置、车辆等。通过摄像头等获取位置信息,该位置信息指示用户头部或耳部的位置。根据该位置信息,控制扬声器的位置,使得作为抗噪声源的扬声器移动从而靠近用户头部或耳部,但与头部或耳部的位置存在间隔,该间隔处于一定范围内目标间隔。在此状态下,使扬声器发出抗噪声,进行降噪。由于扬声器在耳部的附近发出抗噪声,因而能够获得良好的降噪效果。
