摘要：
A sound modification system and a method of managing sound in a vehicle. The system includes an active noise reduction (ANR) controller, an engine sound enhancement (ESE) controller and a sound modification controller. When the vehicle is in a steady state driving condition, the sound modification controller activates the ANR controller and deactivates the ESE controller. In contrast, when the vehicle is in a non-steady state driving condition, the sound modification controller activates the ESE controller and deactivates the ANR controller. Preferably, when the vehicle switches between the steady state and non-steady state driving conditions, the sound modification controller activates and deactivates the ANR and ESE controllers at a rate that is not noticeable to a human. In summary, the system utilizes the ANR and ESE controllers to achieve an optimal passenger cabin experience for the driver during any driving condition.
