Abstract
An active noise cancellation system () for controlling engine noise propagation through a vehicle induction system () is customizable to achieve a desired engine noise profile. A controller () of the active noise cancellation system drives a speaker () to generate a noise cancellation sound in a manner consistent with an individual's indicated preference for a specific type of available engine noise profile. By customizing how the speaker is driven, the system customizes the resulting engine noise heard in the passenger compartment. In one example, the system is customizable using a hand held communication device () such as a cell phone, a personal digital assistant or a so-called palm top computer. In another example, a resident communication bus on the vehicle is accessed through a user communication interface () supported on the vehicle.
