A seat including a sound cancellation system is described. An example vehicle bench seat has a first backrest, a first speaker, a second backrest, a second speaker, a center portion, and a seat base. A first speaker is disposed within the first backrest and a second speaker is disposed within the second backrest. Each of the first speaker and the second speaker emits a primary sound wave and an infrasound wave. The infrasonic wave of the first speaker is 180 degrees out of phase with the main sound wave of the first speaker, and the infrasonic wave of the second speaker is 180 degrees out of phase with the main sound wave of the second speaker. The central portion includes a channel that directs the infrasonic waves emitted by the first and second speakers into the vehicle cabin to cancel unwanted primary sound waves.
