Abstract: A system and method for selectively controlling an electrical component is claimed. The system contains an audio detector, such as a microphone, that receives sound energy and converts the sound energy into a corresponding electrical signal. The content of the sound energy is irrelevant. Rather, it is the volume of the sound energy that is to be represented by the electrical signal. To produce an electrical signal that corresponds to noise volume, the amplitude of the electrical signal is amplified. The amplified signal is then rectified and filtered, thereby producing a D/C electrical signal that is representative of the volume of the sound energy detected. The D/C electrical signal is used to selectively regulate a current flow controller. The current flow controller controls the flow of current to the electronic component.
