**Abstract**

The aim of the study is to present a brief overview of energy policy instrument for monitoring and evaluating holy places and their habitants with the aid of acoustic filters for sensors and transducers. A monitoring protocol for policy instrument is presented for noise protection and security from power systems. Methods of information and data collection are briefly elaborated. The power systems are classified as per source signals of solar power, electric power, light power, sound power, heat power, fluid power and fire power. The acoustic filters as per source of noise signals from power systems are defined. The filters are differentiated as per source signal of unwanted frequencies from solar power, electric power, light power, sound power, heat power, fluid power and fire power. Some examples of acoustic filters are mentioned as per source of noise signal. A slide rule for noise measurement is illustrated along with its noise grades and flag colors under limiting conditions. Some noise filtering results from various power systems of an outdoor duct are also tabulated. An overview of noise systems integration with command and control center is described. A brief discussion on management of holy places and their habitants through monitoring and evaluation is also mentioned.
