Abstract:
1. A hearing aid comprising: a sound acquisition unit configured to acquire an external acoustic signal; a hearing aid processing unit configured to switch between a plurality of algorithms to perform hearing aid processing on the acquired acoustic signal; and an output unit configured to output the acoustic signal on which the hearing aid processing has been performed, said hearing aid comprising: a wind noise detection unit configured to detect wind noise that is mixed in the acquired acoustic signal during the acquisition; and a time variation detection unit configured to detect a time variation of the detected wind noise, wherein said time variation detection unit includes: a pulse detection unit configured to detect a pulse-like variation of the wind noise, as a variation of the wind noise; and a repetition detection unit configured to detect whether or not the detected pulse-like variation repeats with time, and said hearing aid processing unit is configured to switch between the plurality of algorithms to perform the hearing aid processing on the acquired acoustic signal, on the basis of the detected time variation of the wind noise.
