A microphone apparatus using two microphones has a circuit for processing output signals of the two microphones so as to obtain non-directional characteristics in a low frequency region and uni-directional characteristics in a high frequency region. When this microphone apparatus is incorporated in an appliance containing an acoustic noise source and vibration source therein, acoustic noise, vibration noise and wind noise are reduced to prevent a reduction of the S/N ratio when picking up the sound, so that the recording of an excellent quality sound can be realized.
