IN-SEAT SOUND SUPPRESSION

1 . A method comprising:

storing a plurality of passenger profiles regarding passengers of a vehicle, each of the plurality of passenger profiles including a pre-stored physical characteristic of a respective passenger associated therewith, the pre-stored physical characteristic 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;

acquiring passenger identifying data regarding an identity of a present passenger in the vehicle;

identifying a respective passenger profile associated with the present passenger from the plurality of passenger profiles based on the identity of the present passenger; and

controlling a speaker positioned within the vehicle based at least in part on the pre-stored physical characteristic 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.

2 . The method of claim 1 , wherein the noise suppression zone is configured to suppress one or more sounds waves having a frequency less than 2,000 Hz.

3 . The method of claim 2 , wherein the frequency is less than 1,000 Hz.

4 . The method of claim 1 , wherein the speaker is positioned within a seat of the vehicle.

5 . The method of claim 4 , wherein the speaker includes a first speaker positioned along a centerline of the seat, a second speaker laterally offset from the centerline to a first side of the first speaker, and a third speaker laterally offset from the centerline to an opposing second side of the first speaker.

6 . The method of claim 5 , wherein the first speaker is configured to emit the noise-canceling sound waves at a lower frequency than the second speaker and the third speaker.

7 . The method of claim 1 , wherein the speaker is positioned within a headliner of the vehicle.

8 . The method of claim 7 , wherein the speaker includes a first speaker positioned in the headliner directly above the seat, a second speaker positioned in the headliner and laterally offset from the first speaker to a first side of the first speaker, and a third speaker positioned in the headliner and laterally offset from the first speaker to an opposing second side of the first speaker.

9 . The method of claim 8 , wherein the first speaker is configured to emit the noise-canceling sound waves at a lower frequency than the second speaker and the third speaker.

10 . The method of claim 1 , wherein the passenger identifying data is acquired using a biometric sensor positioned within the vehicle.

11 . The method of claim 1 , wherein the passenger identifying data is acquired based on an input received via a user input device of the vehicle.

12 . The method of claim 1 , further comprising performing error tracking and dynamically adjusting the noise suppression zone based on sound data acquired using a microphone positioned within the vehicle.

13 . The method of claim 1 , further comprising dynamically adjusting the noise suppression zone based on movement of the present passenger.

14 . A method comprising:

acquiring passenger identifying data regarding an identity of a passenger present within a seat of a vehicle;

identifying a passenger profile associated with the passenger based on the identity of the passenger, the passenger profile including a pre-stored physical characteristic of the passenger associated therewith; and

controlling a speaker positioned within the vehicle based at least in part on the pre-stored physical characteristic included with the passenger profile to emit noise-canceling sound waves to generate a noise suppression zone to suppress sound waves perceived by the passenger.

15 . The method of claim 14 , wherein the passenger identifying data is acquired using a biometric sensor positioned within the vehicle.

16 . The method of claim 14 , wherein the passenger identifying data is acquired based on an input received via a user input device of the vehicle.

17 . The method of claim 14 , wherein the pre-stored physical characteristic includes at least one of a height of the respective passenger or a typical head position of the respective passenger within the seat of the vehicle.

18 . The method of claim 14 , further comprising dynamically adjusting the noise suppression zone based on movement of the passenger.

19 . A method comprising:

receiving an indication that a passenger is sitting in a seat of a vehicle;

acquiring biometric data of the passenger;

acquiring first passenger data regarding the passenger from a first source based on the biometric data;

acquiring sound data from a microphone within the vehicle;

controlling 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;

acquiring second passenger data from a second source regarding movement of the passenger within the seat; and

dynamically adjusting the noise suppression zone based on the second passenger data.

20 . The method of claim 19 , wherein at least one of:

the first source is a database and the second source is a sensor; or

the indication is received from at least one of the sensor or a user input device.
