Abstract
A noise and vibration measurement arrangement, system, and method are disclosed. The arrangement is configured to operate with an active road noise control system. The arrangement includes an energy harvester, an acceleration sensor, a signal processor, and a signal transmitter. The energy harvester obtains electrical energy from an ambient energy source. The acceleration sensor is configured to generate a sense signal. The signal processor is configured to provide a processed sense signal. The signal processor includes a normal mode of operation and an energy saving mode of operation. The signal transmitter includes a normal mode of operation and an energy saving mode. The energy controller evaluates the electrical energy from the energy harvester to operate in the energy saving mode when the electrical energy is below a predetermined energy level and to operate in the normal mode when the electrical energy is above the predetermined energy level.
