PROBLEM TO BE SOLVED: To provide a wind detector which detects wind accurately.SOLUTION: A wind detector 1 includes: at least two microphones 11, 12; a spectrum analysis section 22 which acquires frequency characteristics representing sound pressure of each frequency band, from a signal of sound detected by the microphones; a sound pressure/dispersion comparison section 23 which compares the acquired frequency characteristics (sound pressure/dispersion) of the two microphones 11, 12; and a wind determination section 24. The wind determination section 24 determines that the sound detected by the two microphones 11, 12 is wind noise when a sound pressure difference between the two microphones 11, 12 is detected over a predetermined frequency band, as a result of the sound pressure/dispersion comparison section 23. |
