When a sound wave in a room is generated, its energy would be indicated by the power of a green or red light. High energy would power the red light and a low energy would power the green light. Sound energy was measured through a sound receiving module (Adafruit Electret Microphone Amplifier - MAX4466, Exhibit 5.E) which gave an average decibel over 1 minute. In turn, the decibel would be converted to a measurement of energy (Joules) through manipulation of equations that involved the use of physic concepts and definite integrals supported through the Fundamental Theorem of Calculus. In conclusion to the results, energy in a room produced by sound waves was shown to be measurable through calculus methods and henceforth, with hardware and software engineering, triggered an indication which is useful for the protection of people within a vicinity.
