A noise detector, a method of detecting noise and an analysis/alert engine. In one embodiment, the noise detector includes: (1) a vibration sensor configured to derive a raw signal from noise proximate the noise detector and (2) a noise score generator, coupled to the vibration sensor, and having a processor configured to generate a noise score based on electrical properties of the raw signal and an ambient sound level that uniquely corresponds to a location of the noise detector, the noise score being insufficient to reproduce a content of the raw signal.
