SPL Traffic Light

SPL Traffic Light lets you monitor SPL levels using colors, by allowing you to set 3 trigger levels at which the display will change colors. You can select from A, C, or Z (flat) weighting, or one of several octave bands. You can also select Fast, Slow, or one of a number of different Leq times. The Leq may be running or may be set to reset at the end of each time limit.

If you are looking for a more flexible SPL monitor, have a look at our Dual SPL Traffic Light, which provides for 2 independent SPL monitors, and also supports emailing notifications of overages.
