Abstract
A method of operating one or more valves of a camless internal combustion engine via electronically controlled valve actuators includes the steps of measuring noise related to valve operation, deriving a control signal based at least in part on the measured noise, and applying the valve control signal to one or more of the valve actuators to reduce the effects of noise attributable to valve operation.
