S.T.L. Visual Noise Detection Unit

The S.T.L. Visual Noise Detection unit is designed to detect very sensitive sounds and convert them to light via four LEDs.  Use it in conjunction with a digital recorder and video camera to verify your EVP's are real. It can also be placed by itself in an area and act as a visual conformation of sounds being detected.
