1. A method for reducing audible noise within an interior of a vehicle comprising:
- collecting live data regarding the audible noise levels for a plurality of frequencies using a microphone;
selecting a particular frequency for review from the plurality of frequencies;
determining if the collected audible noise level for the particular frequency selected for review from the plurality frequencies exceeds a preset maximum level;
adjusting a speed of a rotational component to reduce the noise level for the particular frequency.

6. A method for reducing audible noise within an interior of a vehicle comprising:
-
collecting noise levels for a plurality of frequencies using a microphone; determining if the noise level for a particular frequency selected from the plurality frequencies exceeds a preset maximum level; increasing a speed of a rotational component to move a noise frequency profile within other noise frequencies to reduce the noise audible to occupants of the vehicle for the particular frequency.

7. A method for reducing audible noise within an interior of a vehicle comprising:
-
collecting data related to audible noise levels within a frequency range using a microphone; determining if at least one audible noise level within said frequency range exceeds a preset maximum level; determining if any rotational components are operating; determining if a current operational state of any operating rotational components contributes to the at least one audible noise level within said frequency range; adjusting the operational state of the rotational component to reduce the at least one noise level with said frequency range. - View Dependent Claims (8, 9, 10)

11. A method for reducing audible noise within an interior of a vehicle comprising:
-
collecting data related to audible noise levels within a frequency range using a microphone; determining if at least one audible noise level within said frequency range exceeds a preset maximum level; determining if any rotational components are operating; determining if a current operational state of any operating rotational components contributes to the at least one audible noise level within said frequency range; adjusting the operational state of the rotational component to reduce the at least one noise level with said frequency range; and wherein said step of adjusting the operational state of the rotational component includes the step of increasing a rotational speed of the rotational component.

12. A method for reducing audible noise within the interior of a vehicle comprising:
-
collecting noise levels for a plurality of frequencies using a microphone; determining if said collected noise exceeds a preset maximum noise level in response to a change in vehicle status relating to a change in an open and closed status of a window; and adjusting a speed of a rotational component to reduce audible noise levels when said collected noise is determined to exceed the preset maximum noise level. - View Dependent Claims (13, 14)
