ABSTRACT:
A communication apparatus is disposed at a target place for use in monitoring of sounds. An input section collects various sounds generated at the target place. The collected sounds contain a first type of sound information which should be monitored and a second type of sound information which should not be monitored. The input section converts the collected sounds into a signal capable of conveying the sound information. A signal processing section processes the signal for creating ambiguous sound information by masking, trimming or modifying the second type of the sound information. A transmission section transmits the processed signal to a remote place, where the sounds are reproduced from the transmitted signal and the first type of the sound information is monitored, while the second type of the sound information is not monitored, since the second type of the sound information is altered to the ambiguous sound information.
