This system works by first amplifying an audio input signal and determining a baseline. A detecting unit within the system then detects audio levels at, above or below the baseline level and signals a visual output device allowing a user to view this information. In one embodiment, multiple audio detection systems can be used together or combined into a single instrument to determine if irregularities in white noise levels are occurring in a particular place or direction. In another embodiment, the audio detection system can comprise a white noise generator. | 2012-03-22 |
