1. An adaptive sound control system of an active sound design (ASD) system, comprising:
a state input unit configured to receive an operation state of an infotainment device of a vehicle;
an audio input unit configured to receive an audio signal generated within the vehicle in response to the received operation state being a preset active controllable state;
a signal conversion unit configured to convert the received audio signal into image data;
a network performance unit configured to input the converted image data to a learning-processed classification network configured to classify the image data and output whether the image data is noise data caused by a noise generated by driving of the vehicle or voice data caused by a passenger's voice;
a driving input unit configured to receive driving information of the vehicle in response to the network performance unit outputting that the image data is the noise data; and
an active control unit configured to:
calculate, based on the driving information and the audio signal, first noise level information of the received audio signal;
compare the calculated first noise level information with second noise level information preset by the ASD system; and
control a sound output from the ASD system based on a result of comparing the first and second noise level information.
