To provide communication equipment which dispenses with a microphone dedicated to input peripheral noise.

The communication equipment includes a microphone (1) capable of acquiring an audio signal and a noise signal, a speaker (5) capable of reproducing the audio signal and communication means (8, 9) capable of transmitting/receiving audio signals, wherein it is judged whether a signal acquired by the microphone (1) is an audio signal or a noise signal and when the signal is judged as a noise signal, a phase of the relevant noise signal is inverted, The relevant inverted noise signal and an audio signal acquired from a communicating party by the communication means (8, 9) are synthesized and a noise-reduced audio signal is controlled so as to be output from the speaker (5).
