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 having a processor and memory, coupled to the vibration sensor and configured to generate a noise score from the raw signal, the noise score being insufficient to reproduce a content of the raw signal.
1. A noise detector, comprising:
a vibration sensor configured to derive a raw signal from noise proximate said noise detector, wherein said raw signal has properties that include voltage, current, power, and time; and
a noise score generator having a processor and memory, coupled to said vibration sensor and configured to generate a noise score based on said voltage, said current, said power, and said time, said noise score being insufficient to reproduce a content of said raw signal.
2. The noise detector as recited in claim 1 wherein said vibration sensor is a microphone.
3. The noise detector as recited in claim 1 wherein said noise score is a number and is further based on a frequency content from said raw signal.
4. The noise detector as recited in claim 1 wherein said processor is further configured to generate a time stamp and an identifying number corresponding to said noise detector.
5. The noise detector as recited in claim 1 further comprising a transceiver coupled to said noise score generator and configured to transmit said noise score to a network.
6. The noise detector as recited in claim 1 further comprising a power source coupled to said noise score generator.
7. A method of detecting noise, comprising:
deriving a raw signal having physical properties from noise proximate a noise detector, wherein said physical properties include voltage, current, power, and time; and
generating a noise score based on at least two of said physical properties, said noise score being insufficient to reproduce a content of said raw signal.
8. The method as recited in claim 7 wherein said raw signal is an acoustic signal.
9. The method as recited in claim 7 wherein said generating comprises basing said noise score on at least two of:
an amplitude of a noise event captured in said raw signal,
a frequency content of said noise event, and
a period of time of said noise event.
10. The method as recited in claim 7 further comprising generating a time stamp and an identifying number corresponding to a noise detector carrying out said deriving and said generating.
11. The method as recited in claim 7 further comprising transmitting said noise score to a network.
12. The method as recited in claim 7 further comprising providing power to said noise score generator with a power source contained in a noise detector carrying out said deriving and said generating.
13. An analysis/alert engine, comprising:
a noise score receiver couplable to a network and configured to receive therefrom at least one noise score from a noise detector, wherein said noise detector derives a raw signal having multiple properties from noise proximate said noise detector and generates said noise score from said multiple properties;
a noise score evaluator having a processor, a memory and a host database, associated with said noise score receiver and configured to evaluate said at least one noise score to determine if said at least one noise score should cause an alert to be generated and a destination alert device for said alert; and
an alert transmitter, associated with said noise score evaluator and configured to transmit an alert to said destination alert device.
14. The analysis/alert engine as recited in claim 13 wherein said host database includes at least one threshold corresponding to said noise detector.
15. The analysis/alert engine as recited in claim 13 wherein said noise score evaluator further has a noise signature database including at least one noise signature configured to allow said noise score evaluator to characterize said at least one noise score.
16. The analysis/alert engine as recited in claim 13 wherein said noise score receiver is further configured to receive a time stamp and an identifying number corresponding to said noise detector, employ said time stamp to evaluate said at least one noise score and employ said identifying number to identify said destination alert device.
17. The analysis/alert engine as recited in claim 13 wherein said evaluating comprises comparing multiple of said at least one noise score using time stamps associated therewith.
18. The analysis/alert engine as recited in claim 13 wherein said destination alert device is determined based on a comparison of said noise score to different thresholds.
