Abstract
Systems and methods to cancel noise in a vehicle are disclosed. A first speaker is positioned forward of a steering wheel of a vehicle. The first speaker generates a first signal configured to acoustically cancel noise produced by operation of the vehicle. A second speaker is positioned forward of the steering wheel. The second speaker generates a second signal to acoustically cancel the noise produced by the operation of the vehicle. The first and the second speakers are capable of generating the first and the second signals independently of one another.
Claims20
An apparatus, comprising:
- a first speaker positioned forward of a steering wheel of a vehicle, the first speaker generating a first signal configured to acoustically cancel noise produced by operation of the vehicle;
- and
- a second speaker positioned forward of the steering wheel, the second speaker generating a second signal to acoustically cancel the noise produced by the operation of the vehicle.
An apparatus, comprising:
- a speaker positioned forward of a steering wheel of a vehicle, the speaker configured, in response to a control signal, to generate a noise cancelling signal to acoustically cancel noise produced by operation of the vehicle;
- a plurality of microphones, each of the plurality of microphones configured to convert sensed sound into one of a plurality of input signals;
- and
- a controller in communication with the speaker and the plurality of microphones, the controller configured to receive the plurality of input signals and to execute an active noise cancellation algorithm to generate the control signal.
A method of cancelling noise in a vehicle, the method comprising:
- positioning a first speaker forward of a steering wheel of a vehicle, the first speaker generating a first signal to acoustically cancel noise produced by operation of the vehicle;
- and
- positioning a second speaker forward of the steering wheel, the second speaker generating a second signal to acoustically cancel the noise produced by the operation of the vehicle.
