The invention provides a noise reduction method and device for a Bluetooth vehicle-mounted hands-free system, a vehicle and a storage medium. The method comprises the following steps: monitoring the state of the Bluetooth vehicle-mounted hands-free system; if it is monitored that the state of the Bluetooth vehicle-mounted hand-free system is converted from the non-call state to the call state, whether the current working mode of the vehicle air conditioner is an outer circulation mode or not is judged; and if not, the working mode of the air conditioner is switched into the outer circulation mode. The external circulation mode can be used when the state of the Bluetooth vehicle-mounted hand-free system is in a conversation state, so that the air flow resistance is enhanced based on the long air channel of the external circulation mode, the air volume of the air outlet is small, and the noise in the conversation in the vehicle is reduced.
本发明提供一种蓝牙车载免提系统的降噪方法、装置、车辆及存储介质。该方法包括:监测蓝牙车载免提系统的状态;若监测到蓝牙车载免提系统的状态由未通话转换为通话,则判断车辆空调当前工作模式是否为外循环模式;若否,则将空调的工作模式切换为外循环模式。本发明能够通过在蓝牙车载免提系统的状态为通话时使用外循环模式,进而基于外循环模式的较长风道,增强气流受到的阻力,使出风口的风量偏小,从而降低车内通话时的噪音。
