Abstract
A vehicle includes a passenger capsule, a seat, and a sound suppression system. The passenger capsule includes a headliner. The seat is positioned within the passenger capsule. The seat includes a headrest. The sound suppression system includes one or more speakers and a controller. The one or more speakers are at least one of (i) positioned within the headrest or (ii) positioned within the headliner. The controller is configured to control the one or more speakers to emit sound waves having at least one of a target frequency or a target amplitude to generate a noise suppression zone that projects outward from at least one of the headrest or the headliner toward a passenger sitting in the seat to suppress one or more low frequency sound waves perceived by the passenger.
