Road noise is reduced without locally storing noise spectrum patterns for determination or without detecting the present position of a vehicle from the device. An in-vehicle hands-free device causes a cellular phone to detect the present position of the vehicle and transmit the position to a server. The server determines a noise spectrum pattern corresponding to the road surface on which the vehicle is presently running. The noise spectrum pattern is based on the present position of the vehicle received from the in-vehicle hands-free device and road information. The server transmits the noise spectrum pattern to the in-vehicle hands-free device whereupon a noise canceling signal is superimposed on a received signal. The noise canceling signal is based on an inverted noise spectrum pattern that is obtained by inverting the phase of the noise spectrum pattern. The resulting composite signal is output from a speaker.
