The intuitive design of the Sound Detector makes it easy for users to measure sound levels and helps users determine the attenuation of hearing protection that may be required.
The integrating feature computes the average sound pressure level for more accurate assessment of the intermittent sound levels. When preset levels have been reached, LED indicators flash green, yellow and/or red to give a visual indicator of potentially hazardous noise levels.
The Sound Detector is a compact, lightweight sound level meter designed for measurement of workplace noise levels.
