Abstract
A vehicle system includes a controller that is configured to (a) store a plurality of passenger profiles regarding passengers of a vehicle where each of the plurality of passenger profiles include pre-stored characteristics of a respective passenger associated therewith, (b) acquire passenger identifying data regarding a present passenger in the vehicle, (c) identify a respective passenger profile associated with the present passenger from the plurality of passenger profiles based on the passenger identifying data, and (d) control a speaker positioned within the vehicle based at least in part on the respective passenger profile to emit noise-canceling sound waves to generate a noise suppression zone to suppress sound waves perceived by the present passenger.
Claims20
A vehicle system comprising:
- one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- store a plurality of passenger profiles regarding passengers of a vehicle, each of the plurality of passenger profiles including pre-stored physical characteristics of a respective passenger associated therewith, the pre-stored physical characteristics including at least one of a height of the respective passenger or a typical head position of the respective passenger within a seat of the vehicle;
- acquire passenger identifying data regarding a present passenger in the vehicle;
- identify a respective passenger profile associated with the present passenger from the plurality of passenger profiles based on the passenger identifying data;
- and
- control a speaker positioned within the vehicle based at least in part on the pre-stored physical characteristics included with the respective passenger profile to emit noise-canceling sound waves to generate a noise suppression zone to suppress sound waves perceived by the present passenger.
A vehicle system comprising:
- a first speaker;
- a second speaker;
- a first processing circuit configured to:
- receive an indication that a first passenger is sitting in a first seat of a vehicle;
- acquire a first passenger profile associated with the first passenger, the first passenger profile including pre-stored physical characteristics of the first passenger;
- and
- control the first speaker based at least in part on the pre-stored physical characteristics to emit first noise-canceling sound waves to generate a first noise suppression zone that projects toward the first passenger to suppress one or more sound waves perceived by the first passenger;
- and
- a second processing circuit configured to:
- receive an indication that a second passenger is sitting in a second seat of the vehicle;
- and
- control the second speaker, independent of the first processing circuit, to emit second noise-canceling sound waves to generate a second noise suppression zone that projects toward the second passenger to suppress one or more sound waves perceived by the second passenger.
A vehicle system comprising:
- one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- receive an indication that a passenger is sitting in a seat of a vehicle;
- acquire first passenger data regarding the passenger from the one or more memory devices;
- acquire sound data from a microphone within the vehicle;
- control one or more speakers within the vehicle based at least in part on the sound data and the first passenger data to emit noise-canceling sound waves to generate a noise suppression zone that projects toward the passenger to suppress one or more sound waves perceived by the passenger;
- acquire second passenger data from a sensor regarding movement of the passenger within the seat;
- and
- dynamically adjust the noise suppression zone based on the second passenger data.
