Abstract: In a method for determining vibrations generated by a device, first vibration measurements are received from a first accelerometer coupled to the device, the first vibration measurements comprising a first device vibration contribution and a first environmental vibration contribution, wherein the device is located within an environment comprising a plurality of devices capable of generating vibrations. Second vibration measurements are received from a second accelerometer located within the environment and not connected to the device, the second vibration measurements comprising a second device vibration contribution and a second environmental vibration contribution. The first vibration measurements and the second vibration measurements are compared. Based on the comparing, the first device vibration contribution is estimated. An operational condition of the device is determined based on the estimating, wherein the operational condition is indicative of device performance that may be impacted by device vibration contributions.
