Neural network howling suppression method and system for digital hearing aid and storage medium

The invention provides a neural network howling suppression method for a digital hearing aid, and the method sequentially comprises the following steps: a preprocessing step: receiving a voice signal,carrying out the sampling and framing of the voice signal, and transmitting the voice signal to a howling detection module; A howling detection step: receiving the voice frame by a howling detectionmodule, detecting whether the voice frame is the howling frame by the howling detection module, if the voice frame is not the howling frame, enabling the voice signal to directly pass through, and continuing the subsequent processing; If the frame is the howling frame, entering a buffer inhibition module; And a buffer suppression step: suppressing the howling frame by a buffer suppression module.The method has the beneficial effects that 1, howling frames can be tracked and suppressed in real time, the suppression effect is better, and the algorithm operation complexity is not high; 2, the neural network is adopted for
