Abstract
A sensor is provided in a machine having a continuously variable transmission, for example, and the amount of force exerted by the machine against a load is sensed. Based on the sensed power, an appropriate audio signal is generated which simulates the sounds an operator would expect to hear when such force is applied with a machine having a conventional geared transmission. The sounds can include engine noises, as well as sounds associated with the flow of oil or other hydraulic fluids. In addition, the sounds can be generated from digitally pre-recorded audible data, or can be output based on calculated audible data. User controls are also provided to adjust the volume and frequency or pitch of the generated sounds.
