Abstract

The application relates to the field of hearing aids, in particular to an anti-interference shielding method and system of a hearing aid, a control module, which is used for controlling the operation of multiple modules of the hearing aid, processing collected sound signals, and enabling a wearer to hear surrounding sound, wherein the control module is connected with a sound collecting module, an anti-interference module, a power module, a key, a state prompting module, a sound amplifying module, a sound output module, a storage module and a Bluetooth module. The application detects wind noise by arranging a detection module, switches multiple sound channels to a single microphone working mode when the wind noise exceeds a predetermined value, and automatically carries out noise reduction and repair processing according to the collected sound type if the wind noise does not exceed the predetermined value, so as to ensure the integrity of the received sound signals and facilitate the use of the wearer.
