A vehicle sound synthesis system is provided with a loudspeaker, a microphone and a controller. The loudspeaker is adapted to project sound indicative of synthesized engine noise (SEN) within a cabinof a vehicle in response to receiving an adjusted SEN signal. The microphone is disposed in the cabin and adapted to provide a microphone signal having a SEN component and a noise component. The controller is programmed to receive the microphone signal, adjust a SEN signal based on the microphone signal, and provide the adjusted SEN signal to the loudspeaker. 一种车辆声音合成系统设置有扬声器、麦克风和控制器。所述扬声器适于响应于接收到经调节的SEN信号而在车辆的车厢内投射指示合成发动机噪声(SEN)的声音。所述麦克风设置在所述车厢中并且适于提供具有SEN分量和噪声分量的麦克风信号。所述控制器被编程为接收所述麦克风信号、基于所述麦克风信号调节SEN信号并且将所述经调节的SEN信号提供给所述扬声器。
