Abstract
An active noise cancellation system has a speaker which is utilized to generate sound to cancel engine noise, as is known. An operator horn switch communicates with a control for the active noise cancellation system. Upon receiving a request from the operator for a horn signal, the control for the active noise cancellation system generates a horn tone from the speaker associated with the active noise cancellation system. If cancellation is in progress, the cancellation is preferably paused during the period of time when the horn signal is being emitted.
