The present invention relates to an adaptive volume control system for an Active Sound Design (ASD) system and a method thereof that can control the volume of a virtual engine sound/synthetic engine sound according to a vehicle speed. Since the level of noise (background white noise/background noise) inside a vehicle is different depending on other conditions (road noise, wind noise, etc.) even at the same vehicle speed, the ASD volume is actively controlled while considering the noise level inside the vehicle so that the driving sound quality can be maintained at a constant level. The adaptive volume control system of the ASD system comprises: a state input unit; an audio input unit; a signal conversion unit; a network execution unit; a driving input unit; and an active control unit.
본 발명은 차속에 따라 가상 엔진음/합성 엔진음의 음량을 조절 제어하는 ASD(Active Sound Design) 시스템에 있어서, 동일한 차속을 갖더라도 다른 조건(노면 소음, 풍절음 등)에 따라 차량 내 잡음(배경 잡음/배경 소음) 수준이 상이하기 때문에, 차량 내 잡음 수준까지 고려하여 ASD 음량을 능동 제어함으로써, 주행 음질을 일정하게 유지시킬 수 있는 ASD 시스템의 적응형 음량 제어 시스템 및 그 방법에 관한 것이다.
