Abstract: Provided are a beamforming method and a beamforming system. The beamforming method may comprise the steps of: receiving a first sound signal and a second sound signal by respectively using a first microphone and a second microphone spaced apart from the first microphone by a pre-determined distance; obtaining a Fourier transform result for each of the first sound signal and the second sound signal; obtaining a phase difference between the first sound signal and the second sound signal from the Fourier transform result; performing an arithmetic operation by inputting the phase difference to a beamforming model by using a neural network; performing element multiplication on an operation result of the neural processor and the Fourier transform result for the first sound signal; and outputting a result of the element multiplication.
