Provided are a vehicle sound control system and a method for the same. The vehicle sound control system according to one embodiment of the present invention comprises: a frequency transform part which transforms a sound signal of the time domain input from a sound source of a vehicle to the frequency domain; an equalizer calculation part which makes frequency characteristics according to driving noises at every traveling speed of the vehicle into a database to store and calculates gain for every frequency according to the driving noises; an equalizing control part which boosts a magnitude of voice frequency bandwidth corresponding to voice according to the driving noises by making reference to information calculated in the equalizer calculation part; and a frequency inversion part which inverts the frequency boosted in the equalizing control part to a time domain signal through the short-time Fourier transform (STFT) for output.

    차량 음향 제어 시스템 및 그 방법이 개시된다. 본 발명의 실시 예에 따른 차량 음향 제어 시스템은, 차량의 음향 소스에서 타임 도메인으로 입력되는 음향 신호를 주파수 도메인으로 변환하는 주파수 변환부, 차량의 주행 속도 별 주행 잡음에 따른 주파수 특성을 데이터베이스화하여 저장하고 상기 주행 잡음에 따른 주파수별 게인을 계산하는 이퀄라이저 계산부, 상기 이퀄라이저 계산부에서 계산된 정보를 참조하여 음성에 해당되는 음성 주파수 대역의 크기를 상기 주행 잡음에 따라 부스팅하는 이퀄라이징 제어부 및 상기 이퀄라이징 제어부에서 부스팅 처리된 주파수를 단시간 푸리에 변환(STFT)을 통해 타임 도메인 신호로 변환하여 출력하는 주파수 역변환부를 포함한다.
