Patent ID: 8108217

Claim:
A noise adaptive mobile communication device comprising: a microphone to collect noise from a peripheral environment; a sensor which senses the collected noise; a frequency-component detecting unit which detects a frequency component of the sensed collected noise; a sound generating unit to generate a noise-adaptive sound from the detected frequency component; a call-sound synthesizing unit to synthesize received call sound with the noise-adaptive sound; an operation control unit to control the call-sound synthesizing unit to operate at a predetermined time, to receive positional information of the mobile communication device by using a position tracing service, to identify a peripheral environment in which noise is generated, and to output a sample frequency component corresponding to the identified peripheral environment to the sound generating unit; and a frequency database to store sample frequency components corresponding to noise patterns of peripheral environments, wherein the sound generating unit receives the sample frequency component which is determined from among the sample frequency components stored in the frequency database, to generate the noise-adaptive sound from the received sample frequency component.
