Method for magnetic resonance imaging, MRI, comprising obtaining an image acquisition sequence comprising RF pulses and magnetic field gradients configured to encode spatial information in a part of an object; obtaining an acoustic noise cancelling signal corresponding to the obtained image acquisition sequence at a first position; generating the image acquisition sequence; wherein the magnetic fields gradients are generated by gradient coils configured for three orthogonal directions respectively; and converting, by an acoustic transducer, simultaneously with the image acquisition sequence, the predetermined noise cancelling signal to an acoustic noise cancelling signal at the first position. The noise cancelling signal is obtained based on an acoustic transfer function and the magnetic field gradients of the image acquisition sequence, wherein the acoustic transfer function is obtained by training a neural network on a plurality of generic image acquisition sequences followed by transfer learning with calibration image acquisition sequences obtained during a calibration state before the generating of the image acquisition sequence.
