Abstract
This application relates to the field of audio noise reduction, and provides a method and system for noise reduction in aircraft simulator sounds, a device, and a medium. The method includes: acquiring sound data from an aircraft simulator sound system; classifying the sound data to obtain classified audio data; performing Short-Time Fourier Transform (STFT) processing on the classified audio data to obtain spectral frames; performing noise reduction processing on the spectral frames by using a neural network, to obtain processed spectral frames, where the neural network includes a recurrent neural network and a Deep Q-network (DQN); and performing inverse STFT on the processed spectral frames to obtain denoised audio. This application can achieve low-cost and efficient noise reduction for sounds.
