Abstract
Apparatus and method are provided for reducing acoustical noise when cooling a device, such as a lamp system. The apparatus includes at least a set of a first synthetic jet and a second synthetic jet. The first and second synthetic jets are responsive to respective actuating signals having a phase difference (e.g., 180°) between one another chosen to reduce acoustic noise produced by the first and second synthetic jets when cooling the device.
