Abstract
Seats that include sound cancelation systems are described. An example vehicle bench seat has a first backrest, a first speaker, a second backrest, a second speaker, a central portion, and a seat base. The first speaker is disposed within the first backrest and the second speaker is disposed within the second backrest. Each of the first and second speakers emit primary sound waves and secondary sound waves. The secondary sound waves of the first speaker are 180 degrees out of phase with the primary sound waves of the first speaker and the secondary sound waves of the second speaker are 180 degrees out of phase with the primary sound waves of the second speaker. The central portion includes channels that direct the secondary sound waves emitted by the first and second speakers into the vehicle cabin to cancel undesired primary sound waves.
