The invention provides an in-vehicle noise control method, device and equipment and a readable storage medium, and the method comprises the steps: carrying out the Fourier transform of a time domain signal collected by an in-vehicle microphone when the time domain signal collected by the in-vehicle microphone is not interfered by a loudspeaker, obtaining a frequency domain signal, and determining the frequency domain signal of in-vehicle background noise; superposing the frequency domain signal of the in-vehicle background noise and the frequency domain signal of the host voice, and performing weighting processing and energy superposition on the same frequency on the superposed frequency domain signal to generate a frequency domain signal of a synthetic voice; inverse Fourier transform is carried out on the frequency domain signal of the synthetic voice to obtain a time domain signal, and the time domain signal of the synthetic voice generates a sound wave signal of the synthetic voice through a loudspeaker and outputs the sound wave signal of the synthetic voice. According to the invention, passengers in the vehicle can hear important information such as Bluetooth voice, prompt tone, media voice and the like more clearly.

    本发明提供一种车内噪声控制方法、装置、设备及可读存储介质,包括:当车内麦克风采集的时域信号不受扬声器干扰时,将所述车内麦克风采集的时域信号进行傅里叶变换得到频域信号,确定车内背景噪声的频域信号;将所述车内背景噪声的频域信号和主机语音的频域信号叠加,对叠加得到的频域信号进行加权处理以及相同频率上的能量叠加,生成合成语音的频域信号;将所述合成语音的频域信号进行傅里叶逆变换得到时域信号,将所述合成语音的时域信号通过扬声器生成合成语音的声波信号并输出。通过本发明,可以使车内乘客更加清晰的听到蓝牙语音、提示音、媒体语音等重要信息。
