dBAlert is clipped onto clothing with the microphone facing outwards. If the localised noise exceeds the selected trigger level the hyper-bright warning LED will begin to flash and the vibrating alert will pulse for 15 seconds. Once the noise in the area falls below the threshold for more than 30 seconds, the LED is extinguished and a few short pulses from the vibrate alert will be emitted.
