Hearing aid including wind noise reduction

A hearing aid configured to:

• obtain a first signal comprising first time-frequency values;
• obtain a second signal comprising second time-frequency values;
• determine a third signal comprising third time-frequency by performing first beamforming based on the first signal and the second signal;
• recurringly, determine a first wind noise level based on one or more of:
• the first signal, the second signal, and the third signal;
• determine whether the first wind noise level satisfies a first criterion;
• if the first wind noise level satisfies a first criterion, determine a fourth signal comprising fourth time-frequency values by multiplexing based on the third signal and one or more of the first signal and the second signal,
• if the first wind noise level does not satisfy the first criterion, determine the fourth signal by static selection from one of the third signal, the first signal, and the second signal.
