Abstract
In example implementations described herein, there are systems and methods for performing predictive maintenance which can include collecting vibration data related to an operation of a first machine during a first time period, computing sound data related to the operation of the first machine during the first time period based on the collected vibration data, and predicting, based on the computed sound data, at least one value associated with a maintenance of the first machine. In some aspects, the systems and methods may further include measuring an acoustic transfer function relating the vibration data related to the operation of the first machine to one or more of the sound pressure data or the particle velocity data.
