Abstract
A method includes sensing sound pressure at a specified location, and a controller automatically adjusting a position of one or more fans among a plurality of fans to reduce the sound pressure sensed at the specified location. The position of the one or more fans may, for example, be adjusted using an actuator to change the distance from the fan and the specified location, which may be a location of a user. Optionally, the method may further include the controller automatically adjusting a speed of one or more fans among the plurality of fans to reduce the sound pressure sensed at the specified location. The position and speed of one or more fans may be adjusted to provide destructive interference at the specified location.
