Abstract
A method for disguising the environment and thus the location in which a telephone is being used includes acquiring a disguised environmental sound from a storage device in response to a selection of a user, controlling a voice acquiring device to acquire voice of the user and actual undisguised environmental noise during a call. An environmental noise signal is removed and replaced by an environment-disguising sound signal. An ultrasonic signal can be generated and synthesized with the transmitted voice signal to indicate mis-use of a communication device notwithstanding the environment-disguising noises.
