Abstract
An apparatus for improving the sound of a vehicle according to one embodiment of the present invention, may comprise: a window open/closed detection sensor for detecting the open/closed state of a window of the vehicle; a car door open/closed detection sensor for detecting the open/closed state of a car door of the vehicle; a speed sensor for measuring the speed of the vehicle; a microphone; a memory; and a processor for adjusting a coefficient of an adaptive filter used for an engine order cancellation (EOC) function, on the basis of the opened degree of the window and the speed, when the car door is closed, the window is open, and the magnitude of noise inputted to the microphone is less than or equal to a threshold magnitude.

An apparatus comprising:
- a first sensor configured to determine whether a window of a vehicle is open or closed;
- a second sensor configured to determine whether a door of the vehicle is open or closed;
- a third sensor configured to determine a speed of the vehicle;
- a microphone configured to detect sounds of the vehicle;
- a memory;
- and
- a processor configured to adjust a coefficient of an adaptive filter used in a function based at least in part on a determination that the window of the vehicle is open, the door of the vehicle is closed, and a volume of the sounds of the vehicle into the microphone is less than or equal to a threshold size, wherein the coefficient of the adaptive filter is adjusted based at least in part on a degree that the window of the vehicle is open and the speed of the vehicle.
A method for operating a sound improving apparatus for improving a sound of a vehicle, the method comprising:
- determining whether a window of the vehicle is open or closed and whether a door of the vehicle is open or closed;
- detect sounds of the Vehicle from a microphone;
- determine a speed of the vehicle;
- and
- adjusting a coefficient of an adaptive filter used in a function based at least in part on a determination that the window of the vehicle is open, the door of the vehicle is closed, and a volume of the sounds of the vehicle into the microphone is less than or equal to a threshold size, wherein the coefficient of the adaptive filter is adjusted based at least in part on a degree that the window of the vehicle is open and the speed of the vehicle.
