Abstract
A system includes a microphone, a controller, and a speaker. The microphone is configured to detect noise generated by a functional hardware component due to user interaction with the component. The controller is configured to identify the component from the noise and obtain a noise cancelling signal pre-associated with identification of the component. The speaker is configured to output a noise cancelling sound based on the noise cancelling signal whereby the noise is attenuated.
Claims15
A method comprising:
- detecting noise generated by a functional hardware component in a vehicle during user interaction with the component;
- identifying the component from the noise by comparing the noise with pre-stored sound samplings associated with identification of functional hardware components;
- obtaining a noise cancelling signal pre-associated with the component by comparing identification of the component with identification of functional hardware components associated with pre-stored noise cancelling signals;
- outputting a noise cancelling sound based on the noise cancelling signal.

A system comprising:
- a microphone to detect noise generated by a functional hardware component in a vehicle during user interaction with the component;
- a library having identification of functional hardware components and associated pre-stored noise cancellation signals;
- a controller to identify the component from the noise and obtain the pre-stored noise cancelling signal associated with identification of the component;
- and
- a speaker to output a noise cancelling sound based on the pre-stored noise cancelling signal.

A vehicle comprising:
- a functional hardware component within an interior cabin of the vehicle;
- a microphone configured to detect noise generated by the component during user interaction with the component;
- a first library having pre-stored sound samplings associated with identification of functional hardware components;
- a second library having identification of functional hardware components associated with pre-stored noise cancellation signals;
- a controller configured to identify the component from the noise by comparing the noise with the pre-stored sound samplings associated with identification of functional hardware components of the first library and obtain from the second library the pre-stored noise cancelling signal pre-associated with identification of the component by comparing the identification of the component with identification of functional hardware components associated with the pre-stored noise cancelling signals;
- and
- a speaker configured to output a noise cancelling sound based on the noise cancelling signal whereby the noise is attenuated.
