In-seat sound suppression
A vehicle system includes a non-transitory computer-readable storage medium having instructions stored thereon. The instructions, upon execution by one or more processors, cause the one or more processors to store a plurality of passenger profiles regarding passengers of a 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 a 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. Each of the plurality of passenger profiles includes the pre-stored physical characteristic of a respective passenger associated therewith.
1. A vehicle system comprising:
a non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by 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 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;
acquire passenger identifying data regarding an identity of 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 identity of the present passenger; and
control 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 vehicle system 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 vehicle system of claim 2 , wherein the frequency is less than 1,000 Hz.
4. The vehicle system of claim 1 , further comprising the vehicle, the vehicle including a headliner, the seat, and the speaker.
5. The vehicle system of claim 4 , wherein the speaker is positioned within the seat.
6. The vehicle system of claim 5 , 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.
7. The vehicle system of claim 6 , 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.
8. The vehicle system of claim 4 , wherein the speaker is positioned within the headliner.
9. The vehicle system of claim 8 , 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.
10. The vehicle system of claim 9 , 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.
11. The vehicle system of claim 1 , further comprising a biometric sensor configured to be positioned within the vehicle to acquire the passenger identifying data.
12. The vehicle system of claim 1 , wherein the passenger identifying data is acquired based on an input received via a user input device of the vehicle.
13. The vehicle system of claim 1 , further comprising a microphone configured to be positioned within the vehicle, wherein the microphone is configured to acquire sound data, and wherein the instructions, when executed by the one or more processors, cause the one or more processors to perform error tracking and dynamically adjust the noise suppression zone based on the sound data.
14. The vehicle system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:
acquire movement data regarding movement of the present passenger within the vehicle; and
dynamically adjust the noise suppression zone based on the movement data.
15. A vehicle system comprising:
a non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by one or more processors, cause the one or more processors to:
acquire passenger identifying data regarding an identity of a passenger present within a seat of a vehicle;
identify a passenger profile associated with the passenger based on the the identity of the passenger, the passenger profile including a pre-stored physical characteristic of the passenger associated therewith; and
control 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.
16. The vehicle system of claim 15 , wherein the passenger identifying data is acquired from a sensor configured to be positioned within the vehicle.
17. The vehicle system of claim 15 , wherein the passenger identifying data is acquired based on an input received via a user input device of the vehicle.
18. The vehicle system of claim 15 , 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.
19. A vehicle system comprising:
a non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by 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 biometric data of the passenger;
acquire first passenger data regarding the passenger from a first source based on the biometric data;
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 second source regarding movement of the passenger within the seat; and
dynamically adjust the noise suppression zone based on the second passenger data.
20. The vehicle system 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.
