Protection of Domestic & industrial Electrical system by sensing Sound

There are different ways of detection of system disturbance and then protection of domestic and industrial electrical system. But most of them are relatively costly. Here I want to design a system which is less complex and economical than the remaining system. My total system can also served different purpose such as, power saving traffic light system, emergency lighting system, switch on- off system by making sound, thief detection for domestic areas and etc. Here I use sound and vibration sensor to serve the purpose. The total system is designed to improve the comfort level of an individual person. So a Complete System by Sensing Sound and Vibration for Detection of System Disturbance and Protection of Domestic and Industrial Electric System is designed here.
