The invention relates to a method and system for adjusting the position and volume of a cabin sound field, a vehicle and a storage medium. The method comprises the following steps that noise in different directions outside the vehicle is collected in a preset period; acquiring an equilibrium parameter range of a cabin sound field and a cabin volume range; sound field equalization parameter values are calculated according to noise in different directions outside the vehicle and the equalization parameter range of the cabin sound field, and audio signals output by a cabin sound box are adjusted based on the sound field equalization parameter values, namely, adjustment of the sound field position is achieved; the volume value of the cabin sound box is calculated according to the noise in different directions outside the vehicle and the cabin volume range, and the volume output by the cabin sound box is adjusted based on the volume value of the cabin sound box, so that the volume is adjusted. According to the invention, the sound field position and the volume of the cabin can be automatically adjusted according to the volume and the position of the noise outside the vehicle, so that a driver and passengers can enjoy better sound experience.
本发明涉及一种调节座舱声场位置和音量的方法、系统、车辆及存储介质,包括以下步骤:以预设周期采集车外不同方向的噪音;获取座舱声场的均衡参数范围和座舱音量范围;根据车外不同方向的噪音以及座舱声场的均衡参数范围计算声场均衡参数值,并基于声场均衡参数值调节座舱音箱输出的音频信号,即实现声场位置的调节;根据车外不同方向的噪音以及座舱音量范围计算座舱音箱的音量值,并基于座舱音箱的音量值调节座舱音箱输出的音量,即实现音量大小的调节。本发明能够根据车外噪音的大小和位置自动调节座舱声场位置和音量的大小,以使驾驶员和乘客享受更好的音响体验。
