The invention relates to a sound signal noise reduction method and a hearing aid. The method comprises the steps that based on a sound signal collected by a microphone, an environment scene corresponding to the sound signal is recognized, a first signal-to-noise ratio and a second signal-to-noise ratio matched with the environment scene are determined, the first signal-to-noise ratio is the signal-to-noise ratio when the maximum speech recognition rate is reached after hearing-aid of a user, and the second signal-to-noise ratio is the signal-to-noise ratio when the maximum speech recognition rate is reached after hearing-aid of the user. The second signal-to-noise ratio is a signal-to-noise ratio when the user reaches a speech recognition threshold after hearing aid, and performing noise reduction processing on the sound signal based on the first signal-to-noise ratio or the second signal-to-noise ratio. By adopting the method, personalized noise reduction can be carried out according to the noise tolerance degree of the user and the environmental condition, and the noise reduction effect is effectively improved.
