Abstract : This study evaluates 6 different night-vision goggles (NVGs) to determine if the devices meet the Level II aural-nondetectability standards of MIL-STD-1474E for a detection distance of 10 meters. These systems were tested while mounted on an Advanced Combat Helmet placed on the Knowles Electronic Manikin for Acoustic Research Auditory Test Fixture in an anechoic chamber at the US Army Research Laboratory. All NVG tests were conducted in the automatic gain control mode of operation for each system, and measurements were made at 4 locations around the devices. The results of the testing revealed that all systems passed the aural-nondetectability criteria of 10 m across the 3 tested lighting conditions.
