description 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 a
