    摘要: An example noise and vibration measurement system and method, which is configured to operate with an active road noise control system, includes obtaining electrical energy from an ambient energy source; supplying an acceleration sensor with electrical energy from the energy harvester; generating with the acceleration sensor a sense signal representative of at least one of accelerations, motions and vibrations that act on the acceleration sensor; supplying a signal processor with electrical energy from the energy harvester, the signal processor having a normal mode of operation with a first energy consumption and an energy saving mode of operation with a second energy consumption that is lower than the first energy consumption; and processing the sense signal to provide a processed sense signal. The system and method further comprises supplying a signal transmitter with electrical energy from the energy harvester, the signal transmitter having a normal mode of operation with a third energy consumption and an energy saving mode of operation with a fourth energy consumption that is lower than the third energy consumption; wirelessly broadcasting the sense signal via the signal transmitter; evaluating the electrical energy obtained from the ambient energy source; and controlling at least one of the signal processor and/or signal transmitter to operate in the energy saving mode when the electrical energy from the harvester is below a predetermined energy level and to otherwise operate in the normal mode.

    摘要: An exemplary engine noise control includes directly picking up engine noise from an engine of a vehicle at a pick-up position to generate a sense signal representative of the engine noise, and active noise control filtering to generate a filtered sense signal from the sense signal. The control further includes converting the filtered sense signal from the active noise control filtering into anti-noise and radiating the anti-noise to a listening position in an interior of the vehicle. The filtered sense signal is configured so that the anti-noise reduces the engine noise at the listening position.
