Glass break detector |
摘要 |
The glass break detector uses sampling techniques and statistical analysis of the acoustic signal to determine whether a random type signal typical of a glass break event has been detected. A host of experiments are analysed and the collective results investigated to minimize the effect of one time non-typical occurrences in the signal. The statistical results are preferably used in combination with other techniques for identifying glass break events.
