The invention relates to a vehicle-based prompt tone generation method, device and equipment and a storage medium. The method comprises the steps of obtaining preset sound source data, external white noise source data and internal white noise source data of a vehicle; the external white noise source data represents white noise which is collected outside the vehicle and emitted by an external loudspeaker within a preset frequency band range; the in-vehicle white noise source data represents white noise which is collected in the vehicle and emitted by a loudspeaker outside the vehicle within a preset frequency band range; determining a transmission loss frequency band according to the white noise source outside the vehicle and the white noise source inside the vehicle; the transmission loss frequency band represents the frequency band with loudness loss when the white noise is transmitted from the outside of the vehicle to the inside of the vehicle; and generating a prompt tone according to the preset sound source and the transmission loss frequency band. On the basis of the preset sound source, the warning tone is obtained in combination with the isolation condition of the white noise, and noise pollution of the warning tone to people in the vehicle is reduced.

    本发明涉及一种基于车辆的提示音生成方法、装置、设备及存储介质,包括:获取车辆的预设音源数据、车外白噪音源数据和车内白噪音源数据;车外白噪音源数据表征在车辆外采集到的车外扬声器发出的预设频段范围内的白噪声;车内白噪音源数据表征在车辆内采集到的车外扬声器发出的预设频段范围内的白噪声;根据车外白噪音源和车内白噪音源,确定传递损失频段;传递损失频段表征白噪声从车外传递到车内时存在响度损失的频段;根据预设音源和传递损失频段,生成提示音。以预设音源为基础,结合白噪声的隔离情况,得到提示音,减少提示音对车内人员的噪音污染。
